BAKU, Azerbaijan — For the third straight year, efforts to fight climate change haven’t lowered projections for how hot the world is likely to get — and recent developments in China and the United States are likely to slightly worsen the outlook, according to an analysis Thursday.

The analysis comes as countries come together for the 29th edition of the United Nations climate talks, hosted in Baku, Azerbaijan, where nations are trying to set new targets to cut emissions of heat-trapping gases and figure out how much rich nations will pay to help the world with that task.

But Earth remains on a path to be 2.7 degrees Celsius warmer than pre-industrial times, according to Climate Action Tracker, a group of scientists and analysts who study government policies and translate that into projections of warming.

If emissions are still rising and temperature projections are no longer dropping, people should wonder if the United Nations climate negotiations known as COP are doing any good, said Climate Analytics CEO Bill Hare.

“There’s an awful lot going on that’s positive here, but on the big picture of actually getting stuff done to reduce emissions … to me it feels broken,” Hare said.

Climate action is stifled by the biggest emitters

The world has already warmed 1.3 degrees Celsius above pre-industrial times. That’s near the 1.5-degree limit that countries agreed to at 2015 climate talks in Paris. Climate scientists say the atmospheric warming, mainly from human burning of fossil fuels, is causing ever more extreme and damaging weather including droughts, flooding and dangerous heat.

Climate Action Tracker does projections under several different scenarios, and in some cases, those are going up slightly.

One projected track based on what countries promise to do by 2030 is up to 2.6 degrees Celsius, a tenth of a degree warmer than before. And even the analysts’ most optimistic scenario, which assumes that countries all deliver on their promises and targets, is at 1.9 Celsius, also up a tenth of a degree from last year, said study lead author Sofia Gonzales-Zuniga of Climate Analytics, one of the main groups behind the tracker.

“This is driven highly by China,” Gonzales-Zuniga said. Even though China’s fast-rising emissions are starting to plateau, they are peaking higher than anticipated, she said.

Another upcoming factor not yet in the calculations is the U.S. elections. A Trump administration that rolls back the climate policies in the Inflation Reduction Act, and carries out the conservative blueprint Project 2025, would add 0.04 degree Celsius to warming projections, Gonzales-Zuniga said. That’s not much, but it could be more if other nations use it as an excuse to do less, she said. And a reduction in American financial aid could also reverberate even more in future temperature outlooks.

“For the U.S. it is going backwards,” said Hare. At least China has more of an optimistic future with a potential giant plunge in future emissions, he said.

“We should already be seeing (global) emissions going down” and they are not, Hare said. “In the face of all of the climate disasters we’ve observed, whether it’s the massive floods in Nepal that killed hundreds of people or whether it’s the floods in Valencia, Spain, that just killed hundreds of people. The political system, politicians are not reacting. And I think that’s something that people everywhere should be worried about.”

Experts say $1 trillion is needed in climate cash for developing nation

The major battle in Baku is over how much rich nations will help poor countries to decarbonize their energy systems, cope with future harms of climate change and pay for damage from warming’s extreme weather. The old goal of $100 billion a year in aid is expiring and Baku’s main focus is coming up with a new, bigger figure.

A special independent group of experts commissioned by United Nations Secretary-General Antonio Guterres issued its own estimate of costs and finances on Thursday, calling for a tripling of the old commitment.

“Advanced economies need to demonstrate a credible commitment” to helping poor nations, the report said.

A coalition of poor nations at the Baku talks are asking for $1.3 trillion in annual climate finance. The independent experts’ report said about $1 trillion a year is needed by developing nations from all outside sources, not just government grants.

The report detailed how expensive decarbonizing the world’s economy would be, how much it would cost and where the money could come from. Overall climate adaption spending for all countries is projected to reach $2.4 trillion a year.

“The transition to clean, low-carbon energy, building resilience to the impacts of climate change, coping with loss and damage, protecting nature and biodiversity, and ensuring a just transition, require a rapid step-up in investment in all countries,” said the report.

Washington — National Geographic scientists say they’ve discovered the world’s largest coral near the remote Solomon Islands in the Pacific Ocean — an undersea mass that is so big, it can be seen from space.

The man who found it, Manu San Felix, director of cinematography for National Geographic Society’s Pristine Seas, a program dedicated to marine conservation, says the giant organism measures 34 meters wide and 32 meters long and is “close to the size of a cathedral.”

“I see this as a living library that has the information of the conditions of the oceans for centuries,” he told reporters this week, underscoring it is a reminder of the need to better protect the ocean from global climate change.

Eric Brown, a Pristine Seas coral scientist, said the enormous coral species, Pavona clavus, is healthy and has “high reproductive potential,” making it essential to help other coral reef ecosystems recover from the damage of a warming ocean.

Corals “are very vulnerable ecosystems. So, it’s important for us to do whatever we can to protect these environments that are both small and mighty,” Brown said at a Tuesday press briefing to announce the find.

The announcement comes as world leaders gather for the United Nations climate conference, known as COP29, in Azerbaijan. Attendees are trying to agree on new mechanisms to finance a global energy transition to renewables and help nations like the Pacific Islands pay for the cost of adapting to rising oceans.

Pristine Seas is also encouraging nations to designate marine protected areas, or MPAs. The goal is to protect 30% of the world’s oceans by 2030.

Palau President Surangel Whipps Jr. is attending the summit. Palau has walled off 80% of its waters to development, while the nearby Pacific Island nation of Niue has designated 40% of its waters for protection.

“It cannot just be big countries. Small countries need to do their part,” he told VOA in an interview. “So, it’s all of us working together … protecting our oceans, because we know that healthy oceans are an important part of the ecosystem and important in regulating climate.”

Solomon Islands Prime Minister Jeremiah Manele agreed.

“Our survival depends on healthy coral reefs, so this exciting discovery underlines the importance of protecting and sustaining them for future generations,” he said in a press release.

But so far, the Solomon Islands has created a network of 79 designated ocean conservation areas — less than 1% of its exclusive economic zone. What’s more, its economy is largely dependent on forestry — the very industry that threatens the viability of coral through sedimentation.

“All that sediment is going onto a reef, and it’s smothering the reef, thereby preventing the corals from being able to feed, to grow, to reproduce,” Molly Timmers, Pristine Seas lead scientist on the Solomon Islands, said at the press briefing.

According to the Observatory of Economic Complexity, an online platform that seeks to visualize the distribution of international trade, the Solomons exported $308 million in rough wood in 2022, with $260 million of it going to China.

VOA asked Chief Dennis Marita, director of culture at the Ministry of Culture & Tourism, how the government can find a balance.

“Much of the logging activities are happening on the mainland” away from the coral, Marita said in an interview, but “there needs to be a serious awareness about the impacts of what’s happening in the logging industry to the marine environment.”

Marita sees this coral discovery as a way to attract researchers, biologists and tourists to bring in revenue to the small island nation of 740,000 people. Earlier this week, the Solomon Islands signed an agreement with China to provide visa-free travel between the two countries.

“Suddenly, people will start coming to the island, but then we need to be prepared for them, and also, we need to ensure that the coral is safeguarded,” Marita said.

Dr. Daniel Barshis of Old Dominion University’s Ecological Sciences Department in Norfolk, Virginia, said that idea has merit.

“I would imagine this discovery would draw tourists to the area, similar to how old-growth trees inspire folks to visit,” he told VOA via email.

“The fact that [corals] like this still exist is a reminder that coral reefs are still surviving and deserve us working as hard as we possibly can to save them from some of the worst-case scenarios if we don’t reverse course on greenhouse gas emissions as soon as possible,” said Barshis.

NEW YORK — The decline in U.S. drug overdose deaths appears to have continued this year, giving experts hope the nation is seeing sustained improvement in the persistent epidemic. 

There were about 97,000 overdose deaths in the 12-month period that ended June 30, according to provisional Centers for Disease Control and Prevention data released Wednesday. That’s down 14% from the estimated 113,000 for the previous 12-month period. 

“This is a pretty stunning and rapid reversal of drug overdose mortality numbers,” said Brandon Marshall, a Brown University researcher who studies overdose trends. 

Overdose death rates began steadily climbing in the 1990s because of opioid painkillers, followed by waves of deaths led by other opioids like heroin and — more recently — illicit fentanyl. Provisional data had indicated a slight decline for 2023, and the tally released Wednesday showed that the downward trend has kept going. 

Of course, there have been moments in the last several years when U.S. overdose deaths seemed to have plateaued or even started to go down, only to rise again, Marshall noted. 

“This seems to be substantial and sustained,” Marshall said. “I think there’s real reason for hope here.” 

Experts aren’t certain about the reasons for the decline, but they cite a combination of possible factors. 

One is COVID-19. In the worst days of the pandemic, addiction treatment was hard to get, and people were socially isolated — with no one around to help if they overdosed. 

“During the pandemic we saw such a meteoric rise in drug overdose deaths that it’s only natural we would see a decrease,” said Farida Ahmad of the CDC’s National Center for Health Statistics. 

Still, overdose deaths are well above what they were at the beginning of the COVID-19 pandemic. 

The recent numbers could represent the fruition of years of efforts to increase the availability of the overdose-reversing drug naloxone, and addiction treatments such as buprenorphine, said Erin Winstanley, a University of Pittsburgh professor who researches drug overdose trends. 

Marshall said such efforts likely are being aided by money from settlements of opioid-related lawsuits, brought by state, local and Native American governments against drugmakers, wholesalers and pharmacies. Settlement funds have been rolling out to small towns and big cities across the U.S., and some have started spending the money on naloxone and other measures. 

Some experts have wondered about changes in the drug supply. Xylazine, a sedative, has been increasingly detected in illegally manufactured fentanyl, and experts are sorting out exactly how it’s affecting overdoses. 

In the latest CDC data, overdose death reports are down in 45 states. Increases occurred in Alaska, Nevada, Oregon, Utah and Washington. 

The most dramatic decreases were seen in North Carolina and Ohio, but CDC officials voiced a note of caution. Some jurisdictions have had lags in getting death records to federal statisticians — particularly North Carolina, where death investigations have slowed because of understaffing at the state medical examiner’s office. The CDC made estimates to try to account for incomplete death records, but the decline in some places may ultimately turn out not to be as dramatic as initial numbers suggest. 

Another limitation of the provisional data is that it doesn’t detail what’s happening in different groups of people. Recent research noted the overdose deaths in Black and Native Americans have been growing disproportionately larger. 

“We really need more data from the CDC to learn whether these declines are being experienced in all racial ethnic subgroups,” Marshall said.

Harare, Zimbabwe — Zimbabwe has recorded new cases of cholera several months after declaring the end of an outbreak that killed more than 700 people over an 18-month period. 

On Wednesday, Zimbabwe confirmed a new outbreak of cholera has been recorded in the district of Kariba — on the border with Zambia — where 21 cases have been confirmed and one person died. 

Dr. Godfrey Muza, the Kariba district medical officer, said the government is working to contain the situation: 

“We have set up cholera equipment camp and also some oral rehydration points within the affected villages,” said Muza. “We are getting assistance from our local and regional partners like MSF [Medecins Sans Frontieres, also known as Doctors Without Borders] and UNICEF. And our teams are on the ground doing risk communication and community engagement activities on health promotion, hygiene promotion and assisting the community in terms of improving sanction.”  

In August, the Zimbabwe government declared that the 18-month long cholera outbreak was over. The outbreak  affected up to 35,000 people and claimed more than 700 lives.

Zimbabwe has dealt with cholera outbreaks in the past.  In 2008, an outbreak resulted in more than 98,000 cases and more than 4,000 reported deaths.  

Independent health experts such as Dr. Norman Matara of Zimbabwe Doctors for Human Rights said the government needs to address the conditions that enable the waterborne disease to spread. 

“In public health, we often say cholera is a disease of poverty which mainly affects people with inadequate access to safe water and basic sanitation,” said Matara. “In Zimbabwe, we have witnessed perennial cholera outbreaks in recent years and these outbreaks are being caused by a lack of safe drinking water supply and a broken-down sanitation system which leaves residents in densely populated communities surrounded by flowing sewer. This sewer will then contaminate alternative sources of water such as shower wells, streams, rivers and even boreholes resulting in people drinking or eating food contaminated with the cholera bacteria.” 

He said that those conditions have been chronic over the years in Zimbabwe, contributing to the repeated outbreaks. 

How does Zimbabwe get out of this cycle of recurring cholera outbreaks? 

“We need to make sure that our hospitals are well-supposed with the real addressing solutions and medicines so that people can be assisted,” said Matara. ” … Also, those high-risk communities, especially in towns and urban cities, we may give them the oral cholera vaccine so that they may be protected. In the long term, the government needs to invest more in proper sanitation facilities and infrastructure as well as making sure that people are provided with clean safe water for drinking and cooking.” 

Matara said he hopes the current outbreak is contained quickly and does not spread to other parts of Zimbabwe. 

But with raw sewage flowing in some streets of Harare, it might be a question of time.

BAKU, Azerbaijan — When more than two dozen world leaders deliver remarks at the United Nations’ annual climate conference on Wednesday, many have detailed their nations’ firsthand experience with the catastrophic weather that has come with climate change.

“Over the past year, catastrophic floods in Spain, Bosnia and Herzegovina as well as well as in southern Croatia have shown the devastating impact of rising temperatures,” said Croatia’s prime minister, Andrej Plenkovic. “The Mediterranean, one of the most vulnerable regions, calls for urgent action.”

The Greek prime minister said Europe and the world needs to be “more honest” about the trade-offs needed to keep global temperatures down.

“We need to ask hard questions about a path that goes very fast, at the expense of our competitiveness, and a path that goes some much slower, but allows our industry to adapt and to thrive,” he said. His nation this summer was hammered by successive heat waves after three years of below-average rainfall. In Greece, the misery included water shortages, dried-up lakes and the death of wild horses.

Other speakers on the list include Pakistan Prime Minister Shehbaz Sharif, whose nation has seen deadly flooding this year from monsoon rains that scientists say have become heavier with climate change. Just two years ago, more than 1,700 people died in widespread flooding. Pakistan has also suffered from dangerous heat, with thousands of people hospitalized with heatstroke this spring as temperatures soared to 47 degrees Celsius.

Also on the list of speakers Wednesday is Bahamas Prime Minister Philip Edward Davis. Like many other countries in the Global South, the Bahamas has piled up debt from warming-connected weather disasters it did little to cause, including Hurricanes Dorian in 2019 and Matthew in 2016. Leaders have been seeking help and money from the Global North and oil companies.

Early on Wednesday, ministers and officials from African nations called for initiatives to advance green development on the continent and strengthen resilience to extreme weather events — from floods to droughts — across the region.

Plenty of big names and powerful countries are noticeably absent from COP29 this year. That includes the 13 largest carbon dioxide-polluting countries — a group responsible for more than than 70% of the heat-trapping gases emitted last year — were missing. The world’s biggest polluters and strongest economies — China and the United States — didn’t send their No. 1s. Neither did India and Indonesia.

But U.K. Prime Minister Keir Starmer was there, and he announced an 81% emissions reduction target on 1990 levels by 2035, in line with the Paris Agreement goal to limit warming to 1.5 degrees Celsius above pre-industrial times. That’s up from the 78% the U.K. had already pledged.

The main focus of this year’s talks is climate finance — wealthier nations compensating poor countries for damages from climate change’s weather extremes, helping them pay to transition their economies away from fossil fuels and helping them with adaptation.

TORONTO, canada — A teenager is in critical condition in a British Columbia children’s hospital, sick with Canada’s first presumptive human case of avian influenza.

“This was a healthy teenager prior to this, so no underlying conditions,” said provincial health officer Bonnie Henry in a news conference on Tuesday. “It just reminds us that in young people this is a virus that can progress and cause quite severe illness, and the deterioration that I mentioned was quite rapid.”

British Columbia health officials said on Saturday the province had detected Canada’s first human case of H5 bird flu in a teenager.

Henry said the province is still identifying the exact strain but assumes the case is H5N1.

The World Health Organization says H5N1’s risk to humans is low because there is no evidence of human transmission, but the virus has been found in an increasing number of animals, including cattle in the United States.

Henry would not disclose the teen’s gender or age but said the patient had first developed symptoms on November 2 and was tested on November 8, when admitted to a hospital. Symptoms included conjunctivitis, fever and coughing.

As of Tuesday, the teen was hospitalized with acute respiratory distress syndrome, she said.

The teen had no farm exposure but had been exposed to dogs, cats and reptiles, Henry said. No infection source had been identified. “That is absolutely an ongoing investigation.”

More severe illness takes place when the virus binds to receptors deep in the lungs, she said.

Public health officials had identified and tested about three dozen contacts and had not found anyone infected with the virus.

There has been no evidence that the disease is easily spread between people. But if that were to happen, a pandemic could unfold, scientists have said.

Earlier in November, the U.S. Centers for Disease Control and Prevention asked that farm workers exposed to animals with bird flu be tested for the virus even if they did not have symptoms.

Bird flu has infected nearly 450 dairy farms in 15 U.S. states since March, and the CDC has identified 46 human cases of bird flu since April.

In Canada, British Columbia has identified at least 26 affected premises across the province, Henry said Tuesday, and numerous wild birds have tested positive.

Canada has had no cases reported in dairy cattle and no evidence of bird flu in samples of milk.

BAKU, Azerbaijan — World leaders are converging Tuesday at the United Nations annual climate conference in Baku, Azerbaijan although the big names and powerful countries are noticeably absent, unlike past climate talks which had the star power of a soccer World Cup.

But 2024’s climate talks are more like the International Chess Federation world championship, lacking recognizable names but big on nerd power and strategy. The top leaders of the 13 largest carbon dioxide-polluting countries will not appear. Their nations are responsible for more than 70% of 2023’s heat-trapping gases.

The world’s biggest polluters and strongest economies — China and the United States — aren’t sending their No. 1s. India and Indonesia’s heads of state are also not in attendance, meaning the four most populous nations with more than 42% of all the world’s population aren’t having leaders speak.

“It’s symptomatic of the lack of political will to act. There’s no sense of urgency,” said climate scientist Bill Hare, CEO of Climate Analytics. He said this explains “the absolute mess we’re finding ourselves in.”

Transition to clean energy

The world has witnessed the hottest day, months and year on record “and a master class in climate destruction,” United Nations Secretary-General Antonio Guterres told the world leaders who did show up.

But Guterres held out hope, saying, in a veiled reference to Donald Trump’s re-election in the United States, that the “clean energy revolution is here. No group, no business, no government can stop it.”

United Nations officials said in 2016, when Trump was first elected, there were 180 gigawatts of clean energy and 700,000 electric vehicles in the world. Now there are 600 gigawatts of clean energy and 14 million electric vehicles.

Host Azerbaijan President Ilham Aliyev kicked off two scheduled days of world leaders’ speeches by lambasting Armenia, western news media, climate activists and critics who highlighted his country’s rich oil and gas history and trade, calling them hypocritical since the United States is the world’s biggest oil producer. He said it was “not fair” to call Azerbaijan a “petrostate” because it produces less than 1% of the world’s oil and gas.

Oil and gas are “a gift of the God” just like the sun, wind and minerals, Aliyev said. “Countries should not be blamed for having them. And should not be blamed for bringing these resources to the market because the market needs them.”

As the host and president of the climate talks, called COP29, Aliyev said his country will push hard for a green transition away from fossil fuels, “but at the same time, we must be realistic.”

Lack of star power

Aliyev, United Kingdom’s Prime Minister Keir Starmer and Turkey’s President Recep Tayyip Erdogan are the headliners of around 50 leaders set to speak on Tuesday.

There’ll also be a strong showing from the leaders of some of the world’s most climate-vulnerable countries. Several small island nations presidents and over a dozen leaders from countries across Africa are set to speak over the two-day World Leaders’ Summit at COP29.

As a sense of how the bar for celebrity has lowered, on Tuesday morning photographers and video cameras ran alongside one leader walking through the halls of the meeting. It was the emergency management minister for host country Azerbaijan.

United Nations officials downplayed the lack of head of state star power, saying that every country is represented and active in the climate talks.

One logistical issue is that next week, the leaders of the most powerful countries have to be half a world away in Brazil for the G20 meetings. The United States recent election, Germany’s government collapse, natural disasters and personal illnesses also have kept some leaders away.

The major focus of the negotiations is climate finance, which is rich nations trying to help poor countries pay for transitioning their economies away from fossil fuels, coping with climate change’s upcoming harms and compensating for damages from weather extremes.

Nations are negotiating over huge amounts of money, anywhere from $100 billion a year to $1.3 trillion a year. That money “is not charity, it’s an investment,” Guterres said.

“Developing countries must not leave Baku empty-handed,” Guterres said. “A deal is a must.”

OTTAWA, Ontario — Canada has detected its first presumptive case of H5 bird flu in a person, a teenager in the western province of British Columbia, health officials said Saturday.

The teenager likely caught the virus from a bird or animal and was receiving care at a children’s hospital, the province said in a statement.

The province said it was investigating the source of exposure and identifying the teenager’s contacts. The risk to the public remains low, Canada’s Health Minister Mark Holland said in posting on X.

“This is a rare event,” British Columbia Health Officer Bonnie Henry said in a statement. “We are conducting a thorough investigation to fully understand the source of exposure here in B.C.”

H5 bird flu is widespread in wild birds worldwide and is causing outbreaks in poultry and U.S. dairy cows, with several recent human cases in U.S. dairy and poultry workers.

There has been no evidence of person-to-person spread so far. But if that were to happen, a pandemic could unfold, scientists have said.

Earlier in November, the U.S. Centers for Disease Control and Prevention asked for farm workers who have been exposed to animals with bird flu to be tested for the virus even if they do not have symptoms.

Bird flu has infected nearly 450 dairy farms in 15 U.S. states since March, and the CDC has identified 46 human cases of bird flu since April.

In Canada, British Columbia has identified at least 22 infected poultry farms since October, and numerous wild birds tested positive, according to the province.

Canada has had no cases reported in dairy cattle and no evidence of bird flu in samples of milk.

Most strokes could be prevented, according to new guidelines aimed at helping people and their doctors do just that. 

Stroke was the fourth-leading cause of death in the U.S. in 2023, according to the Centers for Disease Control and Prevention, and more than half a million Americans have a stroke every year. But up to 80% of strokes may be preventable with better nutrition, exercise and identification of risk factors. 

The first new guidelines on stroke prevention in 10 years from the American Stroke Association, a division of the American Heart Association, include recommendations for people and doctors that reflect a better understanding of who gets strokes and why, along with new drugs that can help reduce risk. 

The good news is that the best way to reduce your risk for stroke is also the best way to reduce your risk for a whole host of health problems — eat a healthy diet, move your body and don’t smoke. The bad news is that it’s not always so easy to sustain. 

Dr. Sean Duke, a stroke doctor at the University of Mississippi Medical Center, blames the forces in society that keep people sedentary and eating poorly, like cell phones and cheap, unhealthy food. “Our world is stacked against us,” he said. 

Here’s what to know about stroke and the new guidelines: 

What is a stroke? 

A stroke happens when blood flow to part of the brain is blocked or if a blood vessel in the brain bursts. That deprives the brain of oxygen which can cause brain damage that can lead to difficulty thinking, talking and walking, or even death. 

How eating healthy can reduce your risk for stroke 

Eating healthy can help control several factors that increase your risk for stroke, including high cholesterol, high blood sugar, and obesity, according to the heart association. 

The group recommends foods in the so-called Mediterranean diet such as fruits, vegetables, whole grains and olive oil, which can help keep cholesterol levels down. It suggests limiting red meat and other sources of saturated fat. Instead, get your protein from beans, nuts, poultry, fish and seafood. 

Limit highly processed foods and foods and drinks with a lot of added sugar. This can also reduce your calorie intake, which helps keep weight in check. 

Moving your body can help prevent strokes 

Getting up and walking around for at least 10 minutes a day can “drastically” reduce your risk, said Dr. Cheryl Bushnell, a neurologist at Wake Forest University School of Medicine who was part of the group that came up with the new guidelines. Among the many benefits: Regular exercise can help reduce blood pressure, a major risk factor for stroke. 

Of course, more is better: The heart association recommends at least 150 minutes of moderate aerobic or 75 minutes of vigorous activity — or some combination — per week. How you do it doesn’t matter so much, experts said: Go to the gym, take a walk or run in your neighborhood or use treadmills or stepper machines at home. 

New tools to reduce obesity, a risk factor for stroke 

Diet and exercise can help control weight, another important risk factor for strokes. But a new class of drugs that can drastically reduce weight have been approved by regulators, providing new tools to reduce stroke risk since guidelines were last updated. 

The guidelines now recommend that doctors consider prescribing these drugs, including those sold under the brand names Ozempic, Wegovy, Mounjaro and Zepbound, to people with obesity or diabetes. 

But while those drugs can help, people still need to eat well and get exercise, cautions Dr. Fadi Nahab, a stroke expert at Emory University Hospital. 

Guidelines help identify people who might be at higher risk 

The new guidelines for the first time recommend doctors screen patients for other factors that could increase stroke risk, including sex and gender and non-medical factors such as economic stability, access to health care, discrimination and racism. For example, the risk for having a first stroke is nearly twice as high for Black adults in the U.S. as it is for white adults, according to the CDC. 

“If somebody doesn’t have insurance or they can’t get to a doctor’s office because of transportation issues or they can’t get off work to get health care … these are all things that can impact the ability to prevent stroke,” Bushnell said. 

Doctors may be able to point to resources for low-cost health care or food, and can give ideas about how to be active without breaking the bank for a gym membership. 

The guidelines also now recommend doctors should screen for conditions that could increase a woman’s risk for stroke, such as high blood pressure during pregnancy or early menopause. 

How do I know if I’m having a stroke and what do I do? 

Three of the most common stroke symptoms include face weakness, arm weakness and difficulty speaking. And time is important, because brain damage can happen quickly and damage can be limited if a stroke is treated quickly. Stroke experts have coined an acronym to help you remember: FAST. F for face, A for arm, S for speech, and T for time. If you think you or a loved one could be having a stroke, call 911 right away.

GENEVA — Ahead of next week’s U.N. Climate Change Conference, or COP29, in Baku, Azerbaijan, health experts warn that the climate crisis is also a health crisis and say they must be addressed in tandem to save the planet for future generations.

“Human health and planetary health are intertwined,” U.N. Secretary-General Antonio Guterres said in a statement. “Countries must take meaningful action to protect their people, boost resources, cut emissions, phase out fossil fuels and make peace with nature.”

His call for action is buttressed by Tedros Adhanom Ghebreyesus, the WHO director-general, who calls COP29 “a crucial opportunity for global leaders to integrate health considerations into strategies for adapting to and mitigating climate change.”

In preparation for the climate summit, the World Health Organization, in collaboration with more than 100 organizations and 300 experts, has developed a plan of action to protect the health of all people, “particularly the estimated 3.6 billion people who live in areas which are most susceptible to climate change.”

“This document is a collective call from the health community to make sure that everybody understands the devastating impacts that climate change is having on our health” and to know what actions must be taken to prevent the worst from happening, Dr. Maria Neira, director of the WHO’s Environment Department, told journalists at a briefing Thursday.

“We must move away from fossil fuel subsidies,” she said, noting that “implementing fair carbon pricing and, of course, mobilizing the finance that is needed for climate and health action could save millions of lives every year.”

WHO data show the many ways in which climate change threatens human lives. Between 2030 and 2050, the WHO estimates that climate change will cause 250,000 additional deaths every year “from malnutrition, malaria, diarrhea and heat stress alone.”

Without preventive action, the WHO warns, temperature and precipitation changes will spread death and illness from vector-borne diseases, which currently stand at more than 700,000 a year. It says heat-related deaths among people over age 65 have risen by 70% in two decades and are likely to rise further as the planet heats up.

“If we were to meet the Paris Agreement goals, we would save somewhere in the region of a million lives a year from reduced air pollution alone,” said Dr. Diarmid Campbell-Lendrum, WHO team lead for climate change and health.

The 2016 Paris Agreement on climate change enjoins nations to keep greenhouse gas emissions from rising 1.5 degrees Celsius above preindustrial levels. The U.N. environment agency’s annual emissions gap report, however, finds the world is headed in the wrong direction, with temperatures likely to rise to 3.1 degrees Celsius above preindustrial levels by the end of the century if preventive action is not taken.

“At the moment, the world is currently massively subsidizing fossil fuel consumption,” Campbell-Lendrum said. “The costs of fossil fuel consumption are not only felt in the atmosphere, they are felt in people’s lungs, old people’s lungs, triggering heart attacks and so on, but also young people’s lungs, impairing their development, giving them asthma, hampering their life chances.

“If we were to invest those resources more wisely, then we would have both a healthier planet and also much healthier populations,” he said, adding that financing climate action “is a really good investment, in that you get a lot more back than you put in.”

“We will be able to save almost 2 million lives a year and bring in $4 in benefits for every $1 that you invest in climate action,” he said.

His colleague, Dr. Vanessa Kerry, WHO director-general special envoy for climate change health, agreed that the world cannot afford to ignore the warnings of the impact of climate change on health.

“Whether we choose to recognize it or not, climate change is here. Its impacts are accelerating, altering our ecosystems and communities and threatening our lives.

“Poor health destabilizes economies, widens inequalities and drives political unrest,” she said. “When people cannot access essential needs for their families and lives, it leads to political and social instability. We must address health as a fundamental part of our climate response to prevent these cascading effects.”

Kerry called on leaders gathering for COP29 to urgently “fast-track a just transition and increase funding for health systems” and for frontline health workers to protect the most vulnerable.

London — 2024 is likely to be the hottest year ever recorded, with global warming already exceeding the threshold of 1.5°C above pre-industrial levels, according to scientists, who released the latest data ahead of the COP29 climate summit due to start Monday in Azerbaijan. 

Carlo Buontempo, the director of the European Union’s Copernicus Earth observation program, which produced the data, said it was an important moment for humankind. 

“I call it psychological because it’s something that has been agreed not only among scientists, but between scientists and policymakers and society and nations to use as a reference point. … It is a benchmark with respect to that global discussion,” he told the Associated Press on Thursday. 

Paris Agreement 

Keeping global warming to within 1.5°C of pre-industrial levels was a central pillar of the 2016 Paris Agreement, a deal signed by 196 countries, which forms the basis for the annual COP summits. Scientists say exceeding that threshold will likely have catastrophic impacts. 

“It can be the difference between a country existing, particularly small island developing states, and not. We’re also nearing a lot of Earth system tipping points,” said Ruth Townend, a senior research fellow at Britain’s Chatham House and co-author of its recent report, Azerbaijan’s climate leadership challenge. 

“Our delicate Earth systems are in a fine balance. And once we pass certain thresholds, we can trigger climate impacts that might not be reversible, moving ourselves into new types of systems.” 

Emissions gap 

As for the current trajectory, the United Nations says the world is heading toward around 3°C of warming by the end of this century. 

“We are teetering on a planetary tightrope,” U.N. Secretary-General Antonio Guterres said in a recorded message ahead of the summit. 

“Either leaders bridge the emissions gap or we plunge headlong into climate disaster, with the poorest and most vulnerable suffering the most. This report shows annual greenhouse gas emissions at an all-time high, rising 1.3% last year. They must fall 9% each year to 2030 to limit global temperature rise to 1.5°C and avoid the very worst of climate change,” Guterres said. 

COP29 

Such is the backdrop for the COP29 summit in Baku.  

Over 12 days, hundreds of world leaders and thousands of delegates will enter thorny negotiations on how to cut global greenhouse gas emissions — and, crucially, who should pay for those cuts, along with the adaptation measures necessary to mitigate against climate change caused by past emissions. 

Who pays? 

A key part of COP29 is “to establish the finance in place to help developing countries produce strong new climate plans,” explained Townend.  

“And those climate plans are meant to be delivered ahead of COP30 in Brazil next year. Without the finance domino in that line of dominoes, everything will essentially fall apart a little bit because developing countries won’t have any kind of promise of support from developed countries in order to produce those ambitious new climate plans,” Townend said. 

Fossil fuels 

Some have questioned Azerbaijan’s suitability as host of the summit. It is a major producer of oil and gas — among the fossil fuels that drive climate change.  

“Around 90% of its export revenues come from oil and gas. And it is also a climate vulnerable country — so it gets around 50 to 70% of its water from over its borders, outside its borders,” Townend said. 

“So, it really is between a rock and a hard place on climate action and transition. And as such, it has a really strong interest in getting finance in place to help developing countries such as itself to find a feasible path forward,” she told VOA. 

Trump shadow 

Looming over the summit is Donald Trump’s victory in the Tuesday U.S. presidential election. 

In his first term, Trump withdrew the United States from the Paris Agreement and could do so again once he assumes the presidency in January. He has also pledged to open vast areas of the U.S. for oil and gas drilling. 

There are also fears that Trump’s proposed import tariffs could lead to a trade war with China. The U.S. and China are the top two emitters of greenhouse gases and together account for around a third of global emissions. 

The world must adapt to such tensions, said Townend. 

“We’re unlikely to be moving towards a world that is more stable with increasing climate impact. So, we do need to learn to manage under these conditions of geopolitical instability, which will only increase going forward.” 

Extreme weather 

From the wildfires currently raging in California to the recent deadly floods in Spain’s Valencia, scientists say extreme weather events are a clear indication of the urgency of curbing global warming.  

“There is very strong evidence suggesting that many of these extreme events have become more intense because of climate change. And there is a good understanding of why,” said Buontempo of the EU Copernicus program, who added it’s vital that COP29 is a success. 

“These multilateral negotiations and discussion is the mechanism we have to find a global solution,” he added.

When a volcanic eruption buried the ancient city of Pompeii, the last desperate moments of its citizens were preserved in stone for centuries.

Observers see stories in the plaster casts later made of their bodies, like a mother holding a child and two women embracing as they died.

But new DNA evidence suggests things were not as they seem — and these prevailing interpretations come from looking at the ancient world through modern eyes.

“We were able to disprove or challenge some of the previous narratives built upon how these individuals were kind of found in relation to each other,” said Alissa Mittnik of the Max Planck Institute for Evolutionary Anthropology in Germany. “It opens up different interpretations for who these people might have been.”

Mittnik and her colleagues discovered that the person thought to be a mother was actually a man unrelated to the child. And at least one of the two people locked in an embrace — long assumed to be sisters or a mother and daughter — was a man. Their research was published Thursday in the journal Current Biology.

The team, which also includes scientists from Harvard University and the University of Florence in Italy, relied on genetic material preserved for nearly two millennia. After Mount Vesuvius erupted and destroyed the Roman city in 79 A.D., bodies buried in mud and ash eventually decomposed, leaving spaces where they used to be. Casts were created from the voids in the late 1800s.

Researchers focused on 14 casts undergoing restoration, extracting DNA from the fragmented skeletal remains that mixed with them. They hoped to determine the sex, ancestry and genetic relationships between the victims.

There were several surprises in “the house of the golden bracelet,” the dwelling where the assumed mother and child were found. The adult wore an intricate piece of jewelry, for which the house was named, reinforcing the impression that the victim was a woman. Nearby were the bodies of another adult and child thought to be the rest of their nuclear family.

DNA evidence showed the four were male and not related to one another, clearly showing “the story that was long spun around these individuals” was wrong, Mittnik said.

Researchers also confirmed Pompeii citizens came from diverse backgrounds but mainly descended from eastern Mediterranean immigrants – underscoring a broad pattern of movement and cultural exchange in the Roman Empire. Pompeii is located about 241 kilometers from Rome.

The study builds upon research from 2022 when scientists sequenced the genome of a Pompeii victim for the first time and confirmed the possibility of retrieving ancient DNA from the human remains that still exist.

“They have a better overview of what’s happening in Pompeii because they analyzed different samples,” said Gabriele Scorrano of the University of Rome Tor Vergata, a co-author of that research who was not involved in the current study. “We actually had one genome, one sample, one shot.”

Though much remains to be learned, Scorrano said, such genetic brushstrokes are slowly painting a truer picture of how people lived in the distant past.

Federal health officials on Thursday called for more testing of employees on farms with bird flu after a new study showed that some dairy workers had signs of infection, even when they didn’t report feeling sick. 

Farmworkers in close contact with infected animals should be tested and offered treatment even if they show no symptoms, said Dr. Nirav Shah, principal director of the U.S. Centers for Disease Control and Prevention. 

The new guidance comes after blood tests for 115 farmworkers in Michigan and Colorado showed that eight workers — or 7% — had antibodies that indicated previous infection with the virus known as Type A H5N1 influenza. 

“The purpose of these actions is to keep workers safe, to limit the transmission of H5 to humans and to reduce the possibility of the virus changing,” Shah told reporters. 

The CDC study provides the largest window to date into how the bird virus first detected in March in dairy cows may be spreading to people. It suggests that the virus has infected more humans than the 46 farmworkers identified in the U.S. as of Thursday. Nearly all were in contact with infected dairy cows or infected poultry. 

Outside experts said it’s notable that the study prompted the CDC to take new action. Previous recommendations called for testing and treating workers only when they had symptoms. 

“This is a significant move towards the assessment that these H5N1 viruses are a greater risk than the CDC estimated before,” said Dr. Gregory Gray, an infectious disease researcher at the University of Texas Medical Branch in Galveston. 

Every additional infection in animals or humans gives the virus the chance to change in potentially dangerous ways, said Angela Rasmussen, a virus expert at the University of Saskatchewan in Canada. 

“It shows yet again that we are not responding effectively to the H5N1 cattle outbreak in humans or animals and if we continue to let this virus spread and jump from species to species, our luck will eventually run out,” Rasmussen said in an email. 

The CDC study included 45 workers in Michigan and 70 in Colorado tested between June and August. Of the eight workers with positive blood tests, four reported no symptoms. All eight cleaned milking parlors and none used respiratory protection such as face masks. Three said they used eye protection. 

High levels of the virus have been found in the milk of infected cows, increasing the risk of exposure and infection, researchers said. 

Researchers said that efforts to monitor dairy workers for illness have been hindered by several barriers including the reluctance of farm owners and farmworkers to allow testing. 

The virus has been confirmed in at least 446 cattle herds in 15 states. Last week, the Agriculture Department said a pig at an Oregon farm was confirmed to have bird flu, the first time the virus was detected in U.S. swine.

KINSHASA, DEMOCRATIC REPUBLIC OF CONGO — The spread of mpox has slowed down slightly across Africa, but the epidemic is not over, the African Union’s health watchdog said Thursday.

Fifteen countries across Africa recorded 11,453 mpox cases in the last four weeks, compared with 12,802 in the four weeks prior, the Africa Centers for Disease Control and Prevention said during an online briefing.

But the head of the Africa CDC, Jean Kaseya, warned the epidemic was not over.

“We are still in the acute phase of the outbreak that is pushing us to double our effort to control mpox in Africa,” Kaseya said.

“Unfortunately, we are still losing a number of people,” he said.

Since the start of the year, authorities have recorded 50,840 mpox cases and 1,083 deaths across Africa.

Central Africa accounts for more than 85% of cases and almost all deaths.

The Democratic Republic of Congo, which has recorded more than 39,000 cases and more than 1,000 deaths since the start of the year, launched a vaccination campaign last month that is still “limited,” according to the Africa CDC.

Some 51,649 people have been vaccinated in six provinces, the Africa CDC said.

“We hope that with these vaccines we can continue to support countries to stop this outbreak,” Kaseya said.

Health agencies across the world have allocated just under 900,000 vaccine doses for nine African countries “hard hit by the current mpox surge,” the Africa CDC said in a statement Tuesday.

The countries include the DRC, Kenya and Uganda.

“The largest number of doses — 85% of the allocation — will go to the Democratic Republic of the Congo as the most affected country, reporting four out of every five laboratory confirmed cases in Africa this year,” the statement said.

Mpox, previously known as monkeypox, is caused by a virus transmitted to humans by infected animals but can also be passed from human to human through close physical contact.

It causes fever, muscular aches and large boil-like skin lesions, and can be deadly.

Washington — Researchers at Michigan State University recently discovered that honeybees, with their keen sense of smell, can sniff out lung cancer on a patient’s breath.

“Our world is visual. Insects’ world is all based on smell, so their sense of smell is very, very good,” says Debajit Saha, assistant professor of biomedical engineering at Michigan State University, who was part of a team that published research on the discovery last month.

“There is quite a bit of research that shows that when some cancer grows inside our body, our breath actually changes. Our research does show that honeybees can detect lung cancer and possibly other diseases based on the smell of those cells.”

Saha and his team harnessed the bees and attached electrodes to their brains. The insects were then exposed to synthetic compounds that mimicked the breath of a lung cancer patient. Ninety-three percent of the time, the bees could tell the difference between the cancer breath and the artificial breath of a healthy person. The bees could also distinguish between different types of lung cancer.

The discovery could have implications for early detection of many cancers, including lung, breast, head and neck, and colorectal cancers.

“We do think breath-based diagnostics of cancer can be a game changer,” Saha says. “The reason is, many times we detect the cancer late, when the tumor has already grown pretty big. But generally, when cancer starts growing in your body, the breath signature starts changing much earlier.”

He hopes to develop a portable system in which electrodes are implanted in a honeybee brain that a patient will be able to breathe into. This cyborg sensor, which is part-brain, part-engineered, would deliver test results in real time.

“Hopefully, within the next five years, we’ll have something to show that humans can be diagnosed using these insect brain disc sensors,” Saha says.

Using animals to detect cancer isn’t a new concept. At the Penn Vet Working Dog Center at the University of Pennsylvania, researchers are training dogs to recognize certain cancer odors.

“A lot of other animals also have quite intense and capable senses of smell,” says Cindy Otto, executive director of the Penn Vet Working Dog Center. “But part of what makes dogs so good is that they cooperate with humans, and so, they communicate that information.”

The dogs are in a foster program where they live with families and are brought to “work” each day. Not all dogs can do the work, according to Clara Wilson, a postdoctoral researcher at the center.

“If the dog is not really interested in this type of work, we find out pretty quickly. And you can’t make a dog want to do this, because they’re not going to give you high-quality answers,” Wilson says. “They need to love it to be engaged. And so, it’s a really fun game for them.”

Sniffing out cancer might be a game to the animals, but researchers are finding that the animals detect cancer better than machines. A dog’s sense of smell is 10,000 to 100,000 times more acute than that of humans.

“Why are we finding that these dogs are outperforming the computers?” says Amritha Mallikarjun, another postdoctoral researcher at the center. “Well, part of their success is because of this superior sensitivity to detect odor molecules as compared to anything we currently have on the market.”

The researchers hope to continue isolating characteristics of cancer odors to enhance technological development, eventually creating e-noses that duplicate a dog’s cancer sniffing abilities, enabling earlier detection of cancer.

“This may not be the endgame, but I think it’s going to advance the overall approach to diagnosing not only cancer but many other diseases,” Otto says.

“You can look back in history to the Greeks and Romans. The physicians then used odor as part of their diagnostic tools, and I think as modern humans, we’ve kind of let go of that. I think we can really capitalize on that and advance the health of not only humans, but dogs and other species as well.”

CHICAGO — For the second year in a row, Earth will almost certainly be the hottest it’s ever been. And for the first time, the globe this year reached more than 1.5 degrees Celsius of warming compared to the pre-industrial average, the European climate agency Copernicus said Thursday.

“It’s this relentless nature of the warming that I think is worrying,” said Carlo Buontempo, director of Copernicus.

Buontempo said the data clearly shows the planet would not see such a long sequence of record-breaking temperatures without the constant increase of greenhouse gases in the atmosphere driving global warming.

He cited other factors that contribute to exceptionally warm years like last year and this one. They include El Nino — the temporary warming of parts of the Pacific that changes weather worldwide — as well as volcanic eruptions that spew water vapor into the air and variations in energy from the sun. But he and other scientists say the long-term increase in temperatures beyond fluctuations like El Nino is a bad sign.

“A very strong El Nino event is a sneak peek into what the new normal will be about a decade from now,” said Zeke Hausfather, a research scientist with the nonprofit Berkeley Earth.

News of a likely second year of record heat comes a day after Republican Donald Trump, who has called climate change a “hoax” and promised to boost oil drilling and production, was reelected to the U.S. presidency. It also comes days before the next U.N. climate conference, called COP29, is set to begin in Azerbaijan. Talks are expected to focus on how to generate trillions of dollars to help the world transition to clean energies like wind and solar, and thus avoid continued warming.

Buontempo pointed out that going over the 1.5 degree Celsius threshold of warming for a single year is different than the goal adopted in the 2015 Paris Agreement. That goal was meant to try to cap warming at 1.5 degrees Celsius since pre-industrial times on average, over 20 or 30 years.

A United Nations report this year said that since the mid-1800s on average, the world has already heated up 1.3 degrees Celsius — up from previous estimates of 1.1 degrees or 1.2 degrees. That’s of concern because the U.N. says the greenhouse gas emission reduction goals of the world’s nations still aren’t nearly ambitious enough to keep the 1.5 degree Celsius target on track.

The target was chosen to try to stave off the worst effects of climate change on humanity, including extreme weather. “The heat waves, storm damage, and droughts that we are experiencing now are just the tip of the iceberg,” said Natalie Mahowald, chair of Earth and Atmospheric Sciences at Cornell University.

Going over that number in 2024 doesn’t mean the overall trend line of global warming has, but “in the absence of concerted action, it soon will,” said University of Pennsylvania climate scientist Michael Mann.

Stanford University climate scientist Rob Jackson put it in starker terms. “I think we have missed the 1.5 degree window,” said Jackson, who chairs the Global Carbon Project, a group of scientists who track countries’ carbon dioxide emissions. “There’s too much warming.”

Indiana state climatologist Beth Hall said she isn’t surprised by the latest report from Copernicus, but emphasized that people should remember climate is a global issue beyond their local experiences with changing weather. “We tend to be siloed in our own individual world,” she said. Reports like this one “are taking into account lots and lots of locations that aren’t in our backyard.”

Buontempo stressed the importance of global observations, bolstered by international cooperation, that allow scientists to have confidence in the new report’s finding: Copernicus gets its results from billions of measurements from satellites, ships, aircraft and weather stations around the world.

He said that going over the 1.5 degree Celsius benchmark this year is “psychologically important” as nations make decisions internally and approach negotiations at the annual U.N. climate change summit Nov. 11-22 in Azerbaijan.

“The decision, clearly, is ours. It’s of each and every one of us. And it’s the decision of our society and our policymakers as a consequence of that,” he said. “But I believe these decisions are better made if they are based on evidence and facts.”

An initial 899,000 vaccine doses have been allocated for nine countries across Africa that have been hit hard by the current mpox surge, the WHO and other health organizations said on Wednesday.

The WHO declared mpox a global public health emergency for the second time in two years in August after a new variant of the virus, called clade Ib, spread from the Democratic Republic of Congo to neighboring countries.

In September, after facing criticism on moving too slowly on vaccines, the World Health Organization cleared Bavarian Nordic’s BAVA.CO vaccine for mpox and said it was considering LC16, made by Japan’s KM Biologics as a potential vaccine option.

The WHO also set up a scheme to help bring mpox vaccines, tests and treatments to the most vulnerable people in the world’s poorest countries, similar to efforts during the COVID-19 pandemic.

The global health agency said on Wednesday the newly allocated vaccines will go to the Central African Republic, Ivory Coast, the Democratic Republic of Congo, Kenya, Liberia, Nigeria, Rwanda, South Africa and Uganda.

The largest number of doses – 85% of the allocated vaccines – will go to the Democratic Republic of Congo as the most affected country, the WHO said.

The allocated vaccines are from European countries, the United States, Canada and Gavi, a public-private alliance that co-funds vaccine purchases for low-income countries.

According to the latest WHO figures, there have been more than 46,000 confirmed and suspected cases of mpox in Africa this year, and more than 1,000 deaths in the continent due to the viral illness.

London — Two new cases of the mpox variant clade 1b detected in the U.K. are the first locally transmitted cases in Europe and the first outside Africa, the World Health Organization said Tuesday.

The U.K. Health Security Agency (UKHSA) confirmed late Monday that the two new cases were household contacts of Britain’s first case identified last week, bringing the country’s total confirmed cases to three.

The WHO warned that European states should be prepared for “rapid action” to contain the latest mpox variant, which spreads through close physical contact including sexual relations and sharing closed spaces.

The two cases are also the first to be locally transmitted outside Africa since August 2024, when the WHO declared the outbreak of the new variant an international public health emergency — its highest level of alarm.

Those affected are under specialist care and the risk to the U.K. population “remains low,” UKHSA said.

The original case was detected after the person traveled to several African countries on holiday and returned to the U.K. on Oct. 21.

The patient developed flu-like symptoms more than 24 hours later and, on Oct. 24, started to develop a rash that worsened in the following days.

Mpox, a viral disease related to smallpox, has two types, clade 1 and clade 2. Symptoms include fever, a skin rash or pus-filled blisters, swollen lymph nodes and body aches.

The WHO first declared an international public health emergency in 2022 over the spread of clade 2. That outbreak mostly affected gay and bisexual men in Europe and the United States.

Vaccination and awareness drives in many countries helped stem the number of worldwide cases and the WHO lifted the emergency in May 2023 after reporting 140 deaths out of around 87,400 cases.

In 2024, a two-pronged epidemic of clade 1 and clade 1b, a new strain that affects children, has spread widely in the Democratic Republic of Congo.

The new strain has also been recorded in neighboring Burundi, Kenya, Rwanda and Uganda, with imported cases in Sweden, India, Thailand, Germany and the U.K.

Geneva — The World Health Organization on Tuesday listed 17 pathogens that cause widespread disease and death, including HIV, malaria and tuberculosis, for which it said new vaccines were “urgently needed.”

The U.N. health agency said that it with its list was providing the first global effort to systematically prioritize endemic pathogens based on criteria including disease burdens, antimicrobial resistance risk and the socioeconomic impact.

“We need to do this because we would like to shift the focus from developing vaccines away from commercial returns towards regional and global health needs,” Mateusz Hasso-Agopsowicz, a WHO vaccine specialist, told reporters in Geneva via video link from Poland.

The study reconfirms longstanding priorities for vaccine research and development, including HIV, malaria and tuberculosis — three diseases that collectively kill nearly 2.5 million people each year, WHO said.

But it also identifies lesser-known pathogens as top disease control priorities, highlighting the urgency to develop new vaccines for pathogens that are becoming increasingly resistant to antimicrobials.

Among them was Group A streptococcus, which causes severe infections and contributes to some 280,000 deaths from rheumatic heart disease each year, mainly in lower-income countries.

Ita also highlights the dangers of Klebsiella pneumoniae — a bacterium that is responsible for around 40% of neonatal deaths due to blood infection, or sepsis, in low-income countries.

These vaccines “would not only significantly reduce diseases that greatly impact communities today but also reduce the medical costs that families and health systems face,” WHO vaccine chief Kate O’Brien said in a statement.

Vaccines for the various pathogens listed are at different stages of development, WHO said, with some like ones for HIV, Group A streptococcus and hepatitis C virus still at the research stage. 

Others, like ones for dengue and tuberculosis, have been developed and are approaching regulatory approval or introduction.

Hasso-Agopsowicz explained that the 17 listed pathogens were wreaking the most havoc in lower-income countries, explaining why more progress has not been made previously on developing vaccines against them.

“What typically has happened in the past is that vaccine research and development has been influenced by profitability of new vaccines. What that means is that diseases that severely affect low-income regions unfortunately receive much less attention,” he said.

With the new list, he said, “we want to change the focus… so that the new vaccine research and development is driven by health burden and not just commercial opportunities.”
