Japan to Resume Tourism in June; Only Packaged Tours for Now

Japan will open its borders to foreign tourists in June for the first time since imposing tight pandemic travel restrictions about two years ago, but only for package tours for now, the prime minister said Thursday.

Beginning June 10, Japan will allow the entry of people on tours with fixed schedules and guides, Prime Minister Fumio Kishida said.

Tourists from areas with low COVID-19 infection rates who have received three vaccine doses will be exempt from testing and quarantine after entry.

Japan this week is hosting small experimental package tours from four countries, Australia, Singapore, Thailand and the United States. That experiment, which involves only 50 people who received special visas, not tourist visas, is to end May 31.

“Free and active exchange of people is the foundation of economy and society, as well as that of Asia’s development,” Kishida told his speech at a Tokyo hotel Thursday.

Japan, while watching the infection situation, will gradually accept more tourists in stages to the level of arrivals before the pandemic, he added.

After facing criticism that its strict border controls were xenophobic, Japan began easing its restrictions earlier this year and currently allows entry of up to 10,000 people a day, including Japanese citizens, foreign students and some business travelers.

Japan will double the cap to 20,000 a day from June 1, which will also include package tour participants, said Makoto Shimoaraiso, a Cabinet official in charge of pandemic measures.

The scale of the package tours and other details will be finalized after officials evaluate the results of the current experimental tours, he said.

It will take some time before foreign visitors can come to Japan for individual tourism, Shimoaraiso said.

Japan this week also eased requests for mask wearing. While masks are still requested on public transportation, hospitals and other public facilities, people can take off masks outdoors where others are not around or talking. Despite the easing, most Japanese so far are seen sticking to wearing masks in public.

Japan’s tourism industry, hit hard by the border controls, is eager for foreign tourism to resume. COVID-19 infections have slowed in Japan since earlier this year and the government is gradually expanding social and economic activity.

Kishida said during a visit to London earlier this month that he planned to ease the border controls as early as June in line with the policies of other Group of Seven industrialized countries, but gave no further details.

Foreign tourist arrivals fell more than 90% in 2020 from a record 31.9 million the year before, almost wiping out the pre-pandemic inbound tourism market of more than 4 trillion yen ($31 billion).

Nigerian Albinos Demand Authorities Restore Free Cancer Treatment 

Nigerian Cynthia Ukachi, who has albinism, first noticed the changes on her skin in 2018. When she went to the hospital, she was told it was an early stage of skin cancer, and that it had started because of exposure to the sun.

Thanks to a government support scheme that offered free skin cancer care for albinos, she had surgery to remove the affected areas and was treated.

However, Ukachi says the malignant skin cells returned months ago, long after the government ended its free treatment plan.

“I have three on my neck, I have two at my back and I just have this on my forehead here,” she said. “It looks very small but it’s very painful and it can bleed.”

Without the government support, about 4 million albinos in Nigeria could be at risk of skin cancer, according to aid groups.

Too expensive for her

Ukachi says she cannot afford the treatment. Every affected skin area can cost up to $350 to treat.

“Noticing this issue again, I already knew what it was, but I couldn’t go back to the hospital, knowing I’ll be asked to pay, and the money is what I do not have,” she said. “If the government wants me to live, if the government wants persons with albinism to live, they should reinstate the free cancer treatment.”

Nigerian authorities started the program in 2007, and the Albinism Association of Nigeria says around 5,500 patients including Ukachi benefited from it before it was discontinued for lack of funding.

Jake Epelle, a skin cancer survivor and AAN’s president, said, “Even the current administration started the skeletal implementation at the beginning of their tenure but then reneged. The reason is simply the poverty of funds and the fact that they cannot continue to offer this treatment. The effect is that persons with albinism are dying in droves.”

Medical experts say albinos in sub-Saharan Africa are a thousand times more likely than the general population to develop skin cancer because of the partial or complete absence of melanin, a pigment responsible for eye, hair and skin color.

In Nigeria, myths and discrimination associated with the condition make it far more difficult for albinos to get jobs and afford skin cancer treatment.

Authorities respond

This month, during a national awareness day to remember people living with albinism, AAN renewed its call for the government to reinstate the free skin cancer treatment.

Nigerian authorities responded. James David Lalu, executive secretary of the National Commission for Persons with Disabilities, said, “We had discussions with the permanent secretary of the federal ministry for health for us to be able to revisit this. We’re going to provide some funding support to do that. Additionally, by next year we’re going to provide proper budgetary allocation that will support this cancer treatment for our people.”

AAN cautions there is no time to lose as free treatment is the only lifeline for people around the country like Ukachi, who fears she will run out of time.

Five Ways Climate Change Is Making Poor People Poorer

Heat waves like the ones roasting South Asia this year don’t just sap people’s strength. They drain people’s finances in ways that are not always obvious.

It’s one of the ways climate change is weighing on the economy and making poor people poorer.

“These effects are global, they are pronounced, and they are persistent,” said Teevrat Garg, an economist at the University of California-San Diego’s School of Global Policy and Strategy.

South Asia is especially vulnerable to the impacts of climate change-driven heat waves. But temperature extremes are becoming more common worldwide as the planet warms.

  1. Too hot to work

March and April were the hottest or near-hottest months on record across South Asia.

Climate change made this heat wave about 100 times more likely, according to the U.K. Met Office.

The heat has been brutal for farmers, construction workers and anyone who has to work outside. That’s about half the workforce in South Asia.

“Wage laborers like us work despite the heat,” Indian construction worker Kushilal Mandal told Agence France-Presse in April. “We won’t be able to eat if we don’t work.”

At these temperatures, heatstroke and even death are real risks.

Many work sites shut down early. But that means lost wages.

The U.N. International Labor Organization says that in 2030, hours lost to heat worldwide will be the equivalent of losing at least 80 million full-time jobs.

  1. Lower earnings for outdoor work

It doesn’t take a full work stoppage to hurt workers’ wages. People just can’t do as much when it’s hot.

In a study Garg co-authored, workers in Indonesia in a hot, sunny environment were 8% less productive than those in a shady environment that was about 3 degrees cooler. Doubling wages did not increase productivity.

“It’s not about workers feeling icky or lazy or just like, ‘I don’t want to work because it’s hot,’ ” Garg said. “It’s that heat is representing binding constraints on workers’ ability to do their job.”

  1. Factory slowdowns

Heat affects workers even if they are not exerting themselves. High temperatures slow down factory workers, too.

“We think of manufacturing as a thing that occurs inside. But inside doesn’t mean protected from heat. It doesn’t mean air conditioning,” said World Bank economist Patrick Behrer.

Studies as far back as 1915 show factory workers paid by the piece earn less at higher temperatures. Even call center workers get less done in hot conditions.

“It’s harder for you to pay attention. It’s harder for you to focus. You get tired more easily,” Behrer said. “All of those things feed through to reductions in productivity.”

  1. Workplace injuries

More than wages can be at risk.

“Because you’re paying less attention to what you’re doing or you’re more tired, you’re much more likely to injure yourself,” Behrer said.

On very hot days, workers are about 10% more likely to be injured on the job than on a cool day, Behrer and colleagues found in a study.

That could mean lost wages for the day, or it could be more serious. “If you get hurt on the job, that can be a permanent change in your life,” Behrer said.

  1. Poverty traps

Poorer areas are more vulnerable to the impacts of rising temperatures than wealthier areas, researchers have found. Workers tend to be in industries that are more exposed to heat. And poor people often can’t afford air conditioning. These inequalities are expected to worsen with global warming.

High temperatures also lower crop yields, which lower household incomes in largely agrarian economies such as those of South Asia.

The effects can be passed on to children in these rural households. Garg and colleagues found that students score lower on math and reading tests the year after a hot year, perhaps because their families had less money to spend on education, or even on food or health.

 

Adaptation

Societies can adapt to hotter temperatures. Factories, for example, can buy air conditioning.

But that’s money they won’t spend on better equipment or hiring more workers, Garg noted.

“Adaptation is not free. It’s expensive. It’s costly,” he said. “And in general we find that the poorer you are, the more expensive it is.”

Social safety net programs can help. Garg and colleagues, for example, conducted a study focused on a safety net program in India that supplemented income in rural areas. Since heat waves did not affect farm households’ budgets as much, the effect of heat on students’ test scores was smaller.

With heat waves becoming more common, demand for safety-net programs is growing.

“Countries are already paying for climate change,” Garg said, “because the demand on social protection is rapidly increasing as we get more and more hot days.”

“When we think about climate investments, [typically] we’re thinking about seawalls and green energy. And all of that’s quite important. But … safety net [programs] are going to play a huge role for low- and middle-income populations,” he said.

Pfizer to Offer Low-Cost Medicines, Vaccines to Poor Nations 

Pfizer said Wednesday that it will provide nearly two dozen products, including its top-selling COVID-19 vaccine and treatment, at not-for-profit prices in some of the world’s poorest countries.

The drugmaker announced the program at the World Economic Forum’s annual gathering in Davos, Switzerland, and said it was aimed at improving health equity in 45 lower-income countries. Most of the countries are in Africa, but the list also includes Haiti, Syria, Cambodia and North Korea.

The products, which are widely available in the U.S. and the European Union, include 23 medicines and vaccines that treat infectious diseases, some cancers and rare and inflammatory conditions. Company spokeswoman Pam Eisele said only a small number of the medicines and vaccines are currently available in the 45 countries.

New York-based Pfizer will charge only manufacturing costs and “minimal” distribution expenses, Eisele said. It will comply with any sanctions and all other applicable laws.

The drugmaker also plans to provide help with public education, training for health care providers and drug supply management.

“What we discovered through the pandemic was that supply was not enough to resolve the issues that these countries are having,” Pfizer Chairman and CEO Albert Bourla said Wednesday during a talk at Davos.

He noted that billions of doses of the company’s COVID-19 vaccine, Comirnaty, have been offered for free to low-income countries, mainly through the U.S. government, but those doses can’t be used right now.

Earlier this month, the head of the World Health Organization called on Pfizer to make its COVID-19 treatment more widely available in poorer countries.

Comirnaty brought in nearly $37 billion in sales last year, and analysts expect the company’s COVID-19 treatment Paxlovid to add almost $24 billion this year, according to the data firm FactSet.

Tedros Re-Elected as Head of World Health Organization

The World Health Organization’s (WHO) members re-elected Tedros Adhanom Ghebreyesus as director general by a strong majority for another five years, the president of the World Health Assembly said on Tuesday.

The vote by secret ballot, announced by Ahmed Robleh Abdilleh from Djibouti at a major annual meeting, was seen as a formality since Tedros was the only candidate running.

Ministers and delegates took turns to shake hands and hug Tedros, a former health minister from Ethiopia, who has steered the U.N. agency through a turbulent period dominated by the COVID-19 pandemic. The president had to use a gavel several times to interrupt the applause.

German Health Minister Karl Lauterbach tweeted on Tuesday: “Just re-elected as Director General of #WHO: @DrTedros. 155/160 votes, spectacular result. Congratulations, fully deserved.”

Germany recently overtook the United States as the U.N. health agency’s top donor.

Malawi Rolls Out Cholera Vaccine to Contain Outbreak

Malawi has rolled out a vaccination campaign to help stop an outbreak of cholera.  Authorities report more than 350 cases and 17 deaths from cholera across eight districts of southern Malawi.

Malawi’s Ministry of Health declared the cholera outbreak in early March after the first case was confirmed in the Machinga district in southern Malawi.

The disease has so far spread to eight districts including Nsanje, Chikwawa and Blantyre.

In its latest report on Monday, the ministry said the country had recorded 367 cholera cases in all with 17 deaths and 19 hospital admissions.

Dr. Gertrude Chapotera represented the World Health Organization at the launch of the vaccination campaign Monday in Blantyre.

She said the campaign is running with support from various global partners, including the Gavi Vaccine Alliance and the Global Task for Cholera Control.

“We are supporting the Ministry of Health with up to 3.9 million doses that will be administered in two rounds,” she said. “So this actually is the beginning of the first round with the campaign starting from today the 23rd of May running up Friday this week the 27th of May.”

Cholera is an acute diarrheal infection caused by ingesting food or water contaminated with bacteria. The disease affects both children and adults and, if untreated, can kill within hours.

Dr. Gift Kawalazila is director of Health and Social Services in Blantyre.  He says the district has so far seen nearly 100 cases of cholera, with five deaths but only three hospital admissions as of Monday.

“This means that cholera is a disease that can easily be reversed and we have treatment options with us,” said Kawalazila. “So, the general message to the general population is that they should quickly present themselves to our health workers in our different health facilities whenever they notice the signs and symptoms of cholera which is profuse diarrhea and vomiting in some cases.”

Health authorities say many people are turning up for vaccination, with some districts running short of the doses.

Alinafe Longwe is among those who received the cholera vaccine in Blantyre.  Longwe says she did not get the COVID-19 vaccine, citing fears of blood clotting and other health issues.  

“But with this one, I haven’t heard any issues, so I am okay with it and I have received it and I am fine,” said Longwe.

Meanwhile, the Ministry of Health says it has intensified public education preventing cholera infections. These include the use of clean water for domestic purposes and observing personal hygiene.

WHO Says No Evidence Monkeypox Virus Has Mutated

The World Health Organization does not have evidence that the monkeypox virus has mutated, a senior executive at the U.N. agency said on Monday, noting the infectious disease that is endemic in west and central Africa has tended not to change. 

Rosamund Lewis, head of the smallpox secretariat which is part of the WHO Emergencies Program told a briefing that mutations are typically lower with this virus, although genome sequencing of cases will help inform understanding of the current outbreak.

The more than 100 suspected and confirmed cases in the recent outbreak in Europe and North America have not been severe, the WHO’s emerging diseases and zoonoses lead and technical lead on COVID-19, Maria van Kerkhove, said.

“This is a containable situation,” she said.

The outbreaks are atypical, according to the WHO, as they are occurring in countries where the virus does not regularly circulate. Scientists are seeking to understand the origin of the cases and whether anything about the virus has changed.

COVID Pandemic, Ukraine War Color WHO International Meeting

The Ukraine war, with disease and destruction following in its wake, loomed large Sunday as the WHO convened countries to address a still raging pandemic and a vast array of other global health challenges. 

“Where war goes, hunger and disease follow shortly behind,” World Health Organization chief Tedros Adhanom Ghebreyesus warned on the opening day of the U.N. agency’s main annual assembly.

The assembly, due to run through Saturday, marks the first time the WHO is convening its 194 member states for their first largely in-person gathering since COVID-19 surfaced in late 2019.

Tedros warned that important work at the assembly to address a long line of global health emergencies and challenges, including the COVID-19 crisis, could not succeed “in a divided world.” 

“We face a formidable convergence of disease, drought, famine and war, fueled by climate change, inequity and geopolitical rivalry,” he warned.

The former Ethiopian health minister said he was viewing the ravages in Ukraine through a personal lens: “I am a child of war.”

In Ukraine and elsewhere, he said, it is clear peace “is a prerequisite for health. We must choose health for peace, and peace, peace, peace.”

But it was war that dominated the high-level speeches on the first day of the assembly.

“The consequences of this war are devastating, to health, to populations, to health facilities and to health personnel,” French President Emmanuel Macron said in a video address.

He called on all member states to support a resolution to be presented by Ukraine and discussed by the assembly Tuesday, which harshly condemns Russia’s invasion, especially its more than 200 attacks on health care providers, including hospitals and ambulances, in Ukraine. 

The resolution will also voice alarm at the “health emergency in Ukraine,” and highlight the dire impacts beyond its borders, including how disrupted grain exports are deepening a global food security crisis.

But while Russia has been shunned and pushed out of other international bodies over its invasion, no such sanctions are foreseen at the World Health Assembly.

“There’s not a call to kick them out,” a Western diplomat told AFP, acknowledging the sanctions permitted under WHO rules are “very weak.”

The Ukraine conflict is far from the only health emergency up for discussion this week, with decisions expected on a range of important issues, including on reforms toward strengthening pandemic preparedness. 

“This meeting is a historic opportunity to strengthen universal architecture for security and health,” Dominican Republic President Luis Abinader Corona told the assembly. 

Among the decisions expected at the assembly is Tedros’s reappointment to a second five-year term.

His first term was turbulent, as he helped steer the global response to the pandemic and grappled with other crises, including a sexual abuse scandal involving WHO staff in the Democratic Republic of Congo.

But while he has faced his share of criticism, he has received broad backing and is running unopposed, guaranteeing him a second term.

There will be no shortage of challenges ahead, with the COVID-19 pandemic still raging and demands for dramatic reforms of the entire global health system to help avert similar threats in the future.

And new health menaces already loom, including hepatitis of mysterious origin that has made children in many countries ill, and swelling numbers of monkeypox cases far from Central and West Africa —where the disease is normally concentrated.

One of the major reforms up for discussion involves the WHO budget, with countries expected to greenlight a plan to boost secure and flexible funding to ensure the organization can respond quickly to global health threats.

The WHO’s two-year budget for 2020-21 ticked in at $5.8 billion, but only 16% of that came from regular membership fees.

The idea is to gradually raise the membership fee portion to 50% over nearly a decade, while WHO will be expected to implement reforms, which includes more transparency on its financing and hiring.

The remainder came from voluntary contributions that are heavily earmarked by countries for specific projects.

“There is no greater return on investment than health,” U.N. chief Antonio Guterres told the assembly in a video address.

The COVID pandemic laid bare major deficiencies in the global health system, and countries last year agreed numerous changes were needed to better prepare the world to face future pandemic threats.

Amendments are being considered to the International Health Regulations — a set of legally binding international laws governing how countries respond to acute public health risks.

And negotiations are underway toward a new “legal instrument” — possibly a treaty— aimed at streamlining the global approach to pandemic preparedness and response.But experts warn the reform process is moving too slowly.

Former New Zealand Prime Minister Helen Clark, who co-chaired an expert panel on pandemic preparedness, warned reporters last week little had changed.

“At its current pace, an effective system is still years away, when a pandemic threat could occur at any time,” Clark said.

US High Schoolers Design Low-Cost Filter to Remove Lead From Water

When the pandemic forced schools into remote learning, Washington-area science teacher Rebecca Bushway set her students an ambitious task: design and build a low-cost lead filter that attaches to faucets and removes the toxic metal.

Using 3D printing and high school-level chemistry, the team now has a working prototype — a 7.5-centimeter-tall filter housing made of biodegradable plastic, which they hope to eventually bring to market for $1 apiece.

“The science is straightforward,” Bushway told AFP on a recent visit to the Barrie Middle and Upper School in suburban Maryland, where she demonstrated the filter in action.

“I thought, ‘We have these 3D printers. What if we make something like this?'”

Bushway has presented the prototype at four conferences, including the prestigious spring meeting of the American Chemistry Society, and plans to move forward with a paper in a peer-reviewed journal.

Up to 10 million U.S. homes still receive water through lead pipes, with exposure particularly harmful during childhood.

The metal, which evades a key defense of the body known as the blood-brain-barrier, can cause permanent loss of cognitive abilities and contribute to psychological problems that aggravate enduring cycles of poverty.

A serious contamination problem uncovered in Flint, Michigan, in 2014 is perhaps the most famous recent disaster — but lead poisoning is widespread and disproportionately impacts African Americans and other minorities, explained Barrie team member Nia Frederick.

“And I think that’s something we can help with,” she said.

The harms of lead poisoning have been known for decades, but lobbying by the lead industry prevented meaningful action until recent decades.

President Joe Biden’s administration has pledged billions of dollars from an infrastructure law to fund the removal of all the nation’s lead pipes over the coming years — but until that happens, people need solutions now.

A clever trick

Bushway’s idea was to use the same chemical reaction used to restore contaminated soil: the exposure of dissolved lead to calcium phosphate powder produces a solid lead phosphate that stays inside the filter, along with harmless free calcium.

The filter has a clever trick up its sleeve: under the calcium phosphate, there’s a reservoir of a chemical called potassium iodide.

When the calcium phosphate is used up, dissolved lead will react with potassium iodide, turning the water yellow — a sign it is time to replace the filter.

Student Wathon Maung spent months designing the housing on 3D printing software, going through many prototypes.

“What’s great about it was that it’s kind of this little puzzle that I had to figure out,” he said.

Calcium phosphate was clumping inside the filter, slowing the reaction. But Maung found that by incorporating hexagonal bevels he could ensure the flow of water and prevent clumping.

The result is a flow rate of 9 liters per minute, the normal rate at which water flows out a tap.

Next, the Barrie team would like to incorporate an instrument called a spectrophotometer that will detect the yellowing of the water even before it is visible to the human eye and then turn on a little LED warning light.

Paul Frail, a chemical engineer who was not involved in the work, said the group “deserves an incredible amount of credit” for its work, combining general chemistry concepts with 3D printing to design a novel product.

He added, however, that the filter would need further testing with ion chromatography instruments that are generally available in universities or research labs — as well as market research to determine the demand.

Bushway is confident there is a niche. Reverse osmosis systems that fulfill the same role cost hundreds to thousands of dollars, while carbon block filters available for around $20 have to be replaced every few months, which is more often than her group’s filter.

“I am over-the-moon proud of these students,” Bushway said, adding that the group hoped to work with partners to finalize the design and produce it at scale.

WHO Expects More Cases of Monkeypox to Emerge Globally

The World Health Organization said it expects to identify more cases of monkeypox as it expands surveillance in countries where the disease is not typically found.

As of Saturday, 92 confirmed cases and 28 suspected cases of monkeypox have been reported from 12 member states that are not endemic for the virus, the U.N. agency said, adding it will provide further guidance and recommendations in the coming days for countries on how to mitigate the spread of monkeypox.

“Available information suggests that human-to-human transmission is occurring among people in close physical contact with cases who are symptomatic,” the agency added.

Monkeypox is an infectious disease that is usually mild and is endemic in parts of west and central Africa. It is spread by close contact, so it can be relatively easily contained through such measures as self-isolation and hygiene.

“What seems to be happening now is that it has got into the population as a sexual form, as a genital form, and is being spread as are sexually transmitted infections, which has amplified its transmission around the world,” WHO official David Heymann, an infectious disease specialist, told Reuters.

Heymann said an international committee of experts met via video conference to look at what needed to be studied about the outbreak and communicated to the public, including whether there is any asymptomatic spread, who are at most risk, and the various routes of transmission.

He said the meeting was convened “because of the urgency of the situation.” The committee is not the group that would suggest declaring a public health emergency of international concern, WHO’s highest form of alert, which applies to the COVID-19 pandemic.

He said close contact was the key transmission route, as lesions typical of the disease are very infectious. For example, parents caring for sick children are at risk, as are health workers, which is why some countries have started inoculating teams treating monkeypox patients using vaccines for smallpox, a related virus.

Early genomic sequencing of a handful of the cases in Europe has suggested a similarity with the strain that spread in a limited fashion in Britain, Israel and Singapore in 2018.

Heymann said it was “biologically plausible” the virus had been circulating outside of the countries where it is endemic but had not led to major outbreaks due to COVID-19 lockdowns, social distancing and travel restrictions.

He stressed that the monkeypox outbreak did not resemble the early days of the COVID-19 pandemic because it does not transmit as easily. Those who suspect they may have been exposed or who show symptoms including bumpy rash and fever, should avoid close contact with others, he said.

“There are vaccines available, but the most important message is, you can protect yourself,” he added.

North Korea Reports More Fevers as Kim Claims Virus Progress

North Korea said Saturday it found nearly 220,000 more people with feverish symptoms even as leader Kim Jong Un claimed progress in slowing a largely undiagnosed spread of COVID-19 across an unvaccinated population of 26 million.

The outbreak has caused concern about serious tragedies in the poor, isolated country with one of the world’s worst health care systems and a high tolerance for civilian suffering. Experts say North Korea is almost certainly downplaying the true scale of the viral spread, including a strangely small death toll, to soften the political blow on Kim as he navigates the toughest moment in his decade of rule.

Around 219,030 North Koreans with fevers were identified in the 24 hours through 6 p.m. Friday, the fifth straight daily increase of around 200,000, according to the North’s Korean Central News Agency, which attributed the information to the government’s anti-virus headquarters.

North Korea said more than 2.4 million people have fallen ill and 66 people have died since an unidentified fever began quickly spreading in late April, although the country has only been able to identify a handful of those cases as COVID-19 due to a lack of testing supplies. After maintaining a dubious claim for 2 1/2 years that it had perfectly blocked the virus from entering its territory, the North admitted to omicron infections last week.

Amid a paucity of public health tools, the North has mobilized more than a million health workers to find people with fevers and isolate them at quarantine facilities. Kim also imposed strict restrictions on travel between cities and towns and mobilized thousands of troops to help with the transport of medicine to pharmacies in the country’s capital, Pyongyang, which has been the center of the outbreak.

During a ruling party Politburo meeting on Saturday, Kim insisted the country was starting to bring the outbreak under control and called for tightened vigilance to maintain the “affirmative trend” in the anti-virus campaign, KCNA said. But Kim also seemed to hint at relaxing his pandemic response to ease his economic woes, instructing officials to actively modify the country’s preventive measures based on the changing virus situation and to come up with various plans to revitalize the national economy.

KCNA said Politburo members debated ways for “more effectively engineering and executing” the government’s anti-virus policy in accordance with how the spread of the virus was being “stably controlled and abated,” but the report did not specify what was discussed.

Even while imposing what state media described as “maximum” preventive measures, Kim has stressed that his economic goals still should be met, and state media have described large groups of workers continuing to gather at farms, mining facilities, power stations and construction sites.

Experts say Kim can’t afford to bring the country to a standstill that would unleash further shock on a fragile economy, strained by decades of mismanagement, crippling U.S.-led sanctions over his nuclear weapons ambitions and pandemic border closures.

State media have portrayed an urgent push for agricultural campaigns aimed at protecting crops amid an ongoing drought, a worrisome development in a country that has long suffered from food insecurity, and for completing large-scale housing and other construction projects Kim sees as crucial to his rule.

The virus hasn’t stopped Kim from holding and attending important public events for his leadership. State media showed him weeping during Saturday’s state funeral for top North Korean military official Hyon Chol Hae, who is believed to have been involved in grooming Kim as a future leader during the rule of his father, Kim Jong Il.

North Korea’s optimistic description of its pandemic response starkly contrasts with outside concerns about dire consequences, including deaths that may reach tens of thousands. The worries have grown as the country apparently tries to manage the crisis in isolation while ignoring help from South Korea and the United States. South Korea’s government has said it couldn’t confirm reports that North Korea had flown aircraft to bring back emergency supplies from ally China this week.

The North in recent years has shunned millions of vaccine doses offered by the U.N.-backed COVAX distribution program, possibly because of international monitoring requirements attached to those shots. The WHO and UNICEF have said North Korea so far has been unresponsive to their requests for virus data or proposals for help, and some experts say the North may be willing to accept a certain level of fatalities to gain immunity through infection.

It’s possible at least some of North Korea’s fever caseload are from non-COVID-19 illnesses such as water-borne diseases, which according to South Korean intelligence officials have become a growing problem for the North in recent years amid shortages in medical supplies.

But experts say the explosive pace of spread and North Korea’s lack of a testing regime to detect large numbers of virus carriers in early stages of infection suggest the country’s COVID-19 crisis is likely worse than what its fever numbers represent. They say the country’s real virus fatalities would be significantly larger than the official numbers and that deaths will further surge in coming weeks considering the intervals between infections and deaths.

North Korea’s admission of a COVID-19 outbreak came amid a provocative run of weapons tests, including the country’s first demonstration of an intercontinental ballistic missile since 2017 in March, as Kim pushes a brinkmanship aimed at pressuring the United States to accept the idea of the North as a nuclear power and negotiating economic and security concessions from a position of strength.

The challenges posed by a decaying economy and the COVID-19 outbreak are unlikely to slow his pressure campaign. U.S. and South Korean officials have said there’s a possibility the North conducts another ballistic missile test or nuclear explosive test during or around President Joe Biden’s visits to South Korea and Japan this week.

Nuclear negotiations between Washington and Pyongyang have stalled for more than three years over disagreements over how to relax crippling U.S.-led sanctions in exchange for disarmament steps by the North.

Musk Visits Brazil’s Bolsonaro to Discuss Amazon Rainforest Plans 

Tesla and SpaceX CEO Elon Musk met with Brazil’s President Jair Bolsonaro on Friday to discuss connectivity and other projects in the Amazon rainforest. 

The meeting, held in a luxurious resort in Sao Paulo state, was organized by Communications Minister Fabio Faria, who has said he is seeking partnerships with the world’s richest man to bring or improve internet in schools and health facilities in rural areas using technology developed by SpaceX and Starlink, and also to preserve the rainforest. 

“Super excited to be in Brazil for launch of Starlink for 19,000 unconnected schools in rural areas & environmental monitoring of Amazon,” Musk tweeted Friday morning. 

Illegal activities in the vast Amazon rainforest are monitored by several institutions, such as the national space agency, federal police and environmental regulator Ibama. 

But deforestation in the Brazilian Amazon has surged under Bolsonaro, reaching its highest annual rate in more than a decade, according to official data from the national space agency. Bolsonaro’s critics say he is largely to blame, having emboldened loggers and land grabbers with his fervent support for development of the region. 

During the event, Bolsonaro said the region was “really important” to Brazil. 

“We count on Elon Musk so that the Amazon is known by everyone in Brazil and in the world, to show the exuberance of this region, how we are preserving it, and how much harm those who spread lies about this region are doing to us,” he said. 

Bolsonaro and Musk appeared in a video transmitted live on the president’s Facebook account, standing together on a stage and answering questions from a group of students. 

“A lot can be done to improve quality of life through technology,” Musk told the crowd. 

Although none of the students asked about Musk’s prospective purchase of Twitter, Bolsonaro said that it represented a “breath of hope.” 

“Freedom is the cement for the future,” he said, calling the billionaire a “legend of freedom.” 

Musk has offered to buy Twitter for $44 billion, but said this week the deal can’t go forward until the company provides information about how many accounts on the platform are spam or bots. 

Like Musk, Bolsonaro has sought to position himself as a champion of free speech and has opposed the deplatforming of individuals including his ally, former U.S. President Donald Trump. 

The meeting with Bolsonaro occurs just five months before the far-right leader will seek a second term in a hotly anticipated election.

African Scientists Baffled by Monkeypox Cases in Europe, US 

Scientists who have monitored numerous outbreaks of monkeypox in Africa say they are baffled by the disease’s recent spread in Europe and North America. 

Cases of the smallpox-related disease have previously been seen only among people with links to central and West Africa. But in the past week, Britain, Spain, Portugal, Italy, U.S., Sweden and Canada all reported infections, mostly in young men who hadn’t previously traveled to Africa. 

France, Germany, Belgium and Australia confirmed their first cases Friday. 

“I’m stunned by this. Every day I wake up and there are more countries infected,” said Oyewale Tomori, a virologist who formerly headed the Nigerian Academy of Science and who sits on several World Health Organization advisory boards. 

“This is not the kind of spread we’ve seen in West Africa, so there may be something new happening in the West,” he said. 

To date, no one has died in the outbreak. Monkeypox typically causes fever, chills, a rash and lesions on the face, hands or genitals. WHO estimates the disease is fatal for up to 1 in 10 people, but smallpox vaccines are protective, and some antiviral drugs are being developed. 

British health officials are exploring whether the disease is being sexually transmitted. Health officials have asked doctors and nurses to be on alert for potential cases but said the risk to the general population is low. The European Center for Disease Control and Prevention recommended all suspected cases be isolated and that high-risk contacts be offered smallpox vaccine. 

Nigeria reports about 3,000 monkeypox cases a year, WHO said. Outbreaks are usually in rural areas, when people have close contact with infected rats and squirrels, Tomori said. He said many cases are likely missed. 

Dr. Ifedayo Adetifa, head of the country’s Center for Disease Control, said none of the Nigerian contacts of the British patients have developed symptoms and that investigations were ongoing. 

WHO’s Europe director, Dr. Hans Kluge, described the outbreak as “atypical,” saying the appearance of the disease in so many countries across the continent suggested that “transmission has been ongoing for some time.” He said most of the European cases are mild. 

On Friday, Britain’s Health Security Agency reported 11 new monkeypox cases, saying that “a notable proportion” of the most recent infections in the U.K. and Europe have been in young men with no history of travel to Africa who had sex with men. Authorities in Spain and Portugal said their cases were the same. 

Experts have stressed they do not know if the disease is being spread through sex or other close contact related to sex. 

Nigeria hasn’t seen sexual transmission, Tomori said, but he noted that viruses that hadn’t initially been known to transmit via sex, like Ebola, were later proven to do so after bigger epidemics showed different patterns of spread. 

The same could be true of monkeypox, Tomori said. 

In Germany, Health Minister Karl Lauterbach said the government was confident the outbreak could be contained. He said the virus was being sequenced to see if there were any genetic changes that might have made it more infectious. 

Rolf Gustafson, an infectious diseases professor, told Swedish broadcaster SVT that it was “very difficult” to imagine the situation might worsen. 

“We will certainly find some further cases in Sweden, but I do not think there will be an epidemic in any way,” Gustafson said. “There is nothing to suggest that at present.” 

Scientists said that while it’s possible the outbreak’s first patient caught the disease while in Africa, what’s happening now is exceptional. 

“We’ve never seen anything like what’s happening in Europe,” said Christian Happi, director of the African Centre of Excellence for Genomics of Infectious Diseases. “We haven’t seen anything to say that the transmission patterns of monkeypox have been changing in Africa. So, if something different is happening in Europe, then Europe needs to investigate that.” 

Happi also pointed out that the suspension of smallpox vaccination campaigns after the disease was eradicated in 1980 might inadvertently be helping monkeypox spread. Smallpox vaccines also protect against monkeypox, but mass immunization was stopped decades ago. 

“Aside from people in west and Central Africa who may have some immunity to monkeypox from past exposure, not having any smallpox vaccination means nobody has any kind of immunity to monkeypox,” Happi said. 

Shabir Mahdi, a professor of vaccinology at the University of Witwatersrand in Johannesburg, said a detailed investigation of the outbreak in Europe, including determining who the first patients were, was now critical. 

“We need to really understand how this first started and why the virus is now gaining traction,” he said. “In Africa, there have been very controlled and infrequent outbreaks of monkeypox. If that’s now changing, we really need to understand why.”

In Paris, Green Forum Traces More Durable Footprint for the Planet

People suffering from eco-anxiety — the fear of environmental catastrophe — may get a boost from a green forum in Paris this week. Gathering hundreds of eco-entrepreneurs, companies and activists, ChangeNOW aims to trace a sustainable blueprint for the future.

From food to fashion, technology to transport, a raft of green solutions for our resource-sucking society is parked through Saturday inside a massive events venue — made of sustainable materials — in the shadow of the Eiffel Tower.

“It’s 35 days to reach Madagascar from Marseille. Going through the Suez Canal. And we are using the wind. It helps us to save up to 60 percent energy,” says Louise Chopinet who heads a Brittany-based shipping startup called Windcoop. Its wind-powered sailing vessels carry about 14,000 tons of cargo per trip. For now, that means spices from Madagascar farmers. With the shipping industry challenged to become carbon neutral by 2050, sailing is taking off.

“It’s really a growing interest now. Everyone is getting into sails and wind,” she noted.

Berlin-based Noa Climate also works in Africa. It sells systems that recycle organic waste into energy in places far from power grids. Noa’s Janine Gadke says the company works with financial partners so poor communities can buy products on credit.

“In Kenya, we have a project in an orphanage, they have a system on location … they can get electricity and everything. And they feed the system with kitchen waste,” Gadke expressed.

ChangeNOW is considered one of the biggest global green events of the year. This 5th edition includes CEOs and celebrity activists, like British primatologist Jane Goodall.

Being Paris, representatives of a greening fashion industry are also here, like luxury group LVMH. Also companies pitching natural textiles like silk, cotton, hemp and mohair.

“We can feel a boom in terms of demand,” says Eva Pujol who works for British textile nonprofit The Sustainable Angle; adding that “more and more people are coming and we have brands asking more and more about sustainable material … I think the pressure mostly comes from customers to buy better.”

The forum offers a bicycle parking lot, recyclable waste containers, and a stand cooking up veggie burgers. Those who couldn’t find climate-friendly transport to get here can make a contribution to offset their carbon emissions.

North Korea Hails ‘Good Results’ On COVID as Fever Cases Pass 2 Million

North Korea said Friday it was achieving “good results” in its fight against its first confirmed COVID-19 outbreak, as the number of people with fever symptoms rose past 2 million.

A wave of COVID infections, which North Korea first confirmed last week, has fanned worry about a lack of medical resources and vaccines in the isolated country heavily sanctioned for its nuclear weapons program.

North Korea has not responded to offers from its old enemies, South Korea and the United States, to send help, a South Korean official said.

South Korea’s new president, Yoon Suk Yeol, and U.S. President Joe Biden, who arrived in South Korea on a visit Friday, are expected to discuss help.

North Korea reported 263,370 more people with fever symptoms, and two more deaths, taking its total fever caseload since late April to 2.24 million as of Thursday evening, including 65 deaths, according to its KCNA state news agency.

North Korea lacks COVID testing capacity and it has not specified how many of those people with fever have been confirmed to have contracted COVID.

Despite the caseload, the North has said farming continues and factories are working. It is also planning a state funeral for a retired general.

“Even under the maximum emergency epidemic prevention situation, normal production is kept at key industrial sectors and large-scale construction projects are propelled without let-up,” KCNA reported.

“Good results are reported steadily in the ongoing anti-epidemic war,” it said.

The U.N. human rights agency has warned of the “devastating” consequences of COVID for North Korea’s 25 million people, while World Health Organization officials worry an unchecked spread could lead to the emergence of deadlier new variants.

But North Korea said on Wednesday its outbreak was taking a “favorable turn.”

‘Consultations’

Officials in South Korea say it is hard to draw conclusions, partly because it is not clear how North Korea is calculating the number of fever and COVID patients.

Cases of fever reported by the government have declined in the capital, Pyongyang, but risen in rural provinces.

But Martyn Williams, a researcher at the U.S.-based 38 North monitoring group, said North Korea’s figures were unlikely to give an accurate account of what is going on, either through error or deliberate manipulation.

“I doubt they represent the exact picture,” he said on Twitter.

South Korea and the United States have both offered to help North Korea fight the virus, including sending aid, but have not had a response, South Korea’s deputy national security adviser said.

But the allies, who North Korea denounces as its main enemies as it justifies its development of nuclear weapons and missiles, would likely be North Korea’s last resort in seeking help, said South Korean legislators who were briefed by its main security agency on Thursday.

South Korea’s foreign minister, Park Jin, told parliament Yoon and Biden would discuss help for North Korea when they meet Saturday.

“South Korea and the United States are continuing consultations on providing humanitarian assistance, especially over COVID-19, to the North,” Park said.

Boeing Crew Capsule Launches to Space Station in 2nd Test 

Boeing’s crew capsule rocketed into orbit Thursday on a repeat test flight without astronauts, after years of being grounded by flaws that could have doomed the spacecraft.

Only a test dummy was aboard. If the capsule reaches the International Space Station on Friday and everything else goes well, two or three NASA test pilots could strap in by the end of this year or early next for the company’s first crew flight.

It’s Boeing’s third shot at the high-stakes flight demo.

At least this time, Starliner made it to the proper orbit, quickly giving chase to the space station. But the all-important rendezvous and docking loomed.

Starliner’s first test flight in 2019 was stricken by software errors so severe that the capsule ended up in the wrong orbit and had to skip the space station. The spacecraft came close to being destroyed as ground controllers hastily cut short the mission.

After dozens of safety fixes, Boeing returned a different capsule to the launch pad last summer. Corroded valves halted the countdown, resulting in another round of repairs.

The drawn-out test flight program has cost Boeing about $600 million.

“We’re not going to fly (crews) unless we feel like we’ve bought down the risk,” NASA space operations chief Kathy Lueders stressed on the eve of liftoff.

Boeing is seeking redemption as it attempts to catch up with SpaceX, NASA’s other contracted taxi service. Elon Musk’s company has been flying astronauts to and from the space station for two years and delivering cargo for a full decade.

Eager to reduce its high-priced dependency on Russia for crew transport, NASA hired Boeing and SpaceX to launch astronauts to the space station after the shuttle program ended in 2011. That’s why it’s so important for Boeing’s Starliner to succeed, said NASA Administrator Bill Nelson.

“We always, in this case, want to have a backup,” Nelson told The Associated Press hours before liftoff.

Different in looks but similar in function to SpaceX’s Dragon capsule, Boeing’s fully automated capsule will attempt to dock at the space station on its own. Station astronauts will be ready to steer the capsule by remote control, if necessary.

Starliner will spend close to a week at the space station before aiming for a touchdown in the New Mexico desert.

NASA has yet to finalize which astronauts will be on the first Starliner crew. The program is so far behind that the original three have stepped aside. The leading candidates gathered at Cape Canaveral for the evening launch of Starliner atop United Launch Alliance’s Atlas V rocket.

“We’re thrilled for this because the next one is us,” said astronaut Butch Wilmore.

Besides Rosie the Rocketeer — a space-age version of World War II’s Rosie the Riveter — the capsule is carrying groceries and spacewalking gear for the seven station residents. U.S. spacewalks have been on hold since an astronaut’s helmet took on water in March. NASA is sending up extra absorbent pads for use in helmets, in case an emergency spacewalk is required as the investigation continues.

Boeing also is flying mementos from historically black colleges and universities and tree seeds similar to those Apollo astronauts took to the moon that became so-called moon trees here on Earth.
