The African Union has announced that Johnson & Johnson COVID-19 vaccines assembled in South Africa will no longer be exported to Europe and will instead be distributed among African countries.In addition, millions of J&J vaccines already shipped to Europe, but currently stored in warehouses, will be returned to South Africa, African Union COVID-19 envoy Strive Masiyiwa said Thursday.The deal between J&J and Aspen Pharmacare, the South African facility manufacturing the J&J vaccines that were sent to Europe, had received harsh criticism as less than 3% of the population of the African continent has been inoculated, compared to richer regions of the world that have begun or will soon begin booster shot campaigns.The World Health Organization has warned that the pandemic cannot be brought under control unless all the world’s regions are equitably vaccinated.Meanwhile, WHO has listed a new coronavirus strain as a “variant of interest.” The Mu variant is responsible for nearly 40% of the COVID cases in Colombia where it was first identified.Greek health care workers demonstrated Thursday against a COVID mandate that went into effect Wednesday.Under the new regulation, workers will be suspended without pay if they have not been inoculated or recovered from the coronavirus in the last six months.Musicals are back on Broadway, after an absence of more than a year because of the COVID-19 pandemic.  Tony Award-winning Hadestown, a modern interpretation of the ancient Greek legend of lovers Orpheus and Eurydice, opened Thursday.Also, the musical Waitress began a limited run Thursday, starring singer-songwriter Sara Bareilles.Hamilton, The Lion King, and Wicked return to Broadway theaters Sept. 14.The Johns Hopkins Coronavirus Resource Center has recorded 219 million COVID infections and 4.5 million coronavirus deaths.  The center said early Friday that 5.3 billion vaccines have been administered.  Some information for this report came from the Associated Press.

Racial minorities in the United States will bear a disproportionate burden of the negative health and environmental impacts from a warming planet, the Environmental Protection Agency said Thursday, including more deaths from extreme heat and property loss from flooding in the wake of sea-level rise.The new analysis, which comes four days after Hurricane Ida destroyed homes of low-income and Black residents in Louisiana and Mississippi, examined the effects of the global temperature rising 2 degrees Celsius compared with preindustrial levels. It found that American Indians and Alaska Natives are 48% more likely than other groups to live in areas that will be inundated by flooding from sea-level rise under that scenario, Latinos are 43% more likely to live in communities that will lose work hours because of intense heat, and Black people will suffer significantly higher mortality rates.The world has already warmed 1.1 degrees Celsius since the Industrial Revolution began and is on track to warm by more than 1.5 degrees by the early 2030s.Joe Goffman, acting head of the EPA’s Office of Air and Radiation, said the comprehensive review was a “first of its kind.” It amounts to a federal acknowledgment of the broad and disproportionate effect that global warming is having on some of America’s most socially vulnerable groups. Just this week, the Department of Health and Human Services established the Office of Climate Change and Health Equity, the first federal program aimed at specifically examining how the burning of fossil fuels and other greenhouse gas emissions affect human health.The impact of Hurricane Ida, whose remnants Wednesday wreaked havoc in New Jersey and New York City, is still being calculated. But Goffman said many Black and low-income residents in Louisiana and Mississippi are faced with the challenge of mustering the resources to replace living rooms drowned in floodwaters and rooftops ripped apart by powerful winds.“But one of the underlying lessons of this report is that so many communities that are heavily Black and African American find themselves in the way of some of the worst impacts of climate change,” he said, “as was the case with Katrina and, we may find, turns out to be the case with Ida.”Cristiane Rosales Fajardo, a community organizer in New Orleans who said she took in more than three dozen undocumented residents displaced by Ida, said people of color need more support after storms in part because they helped bring the city back from the brink after Hurricane Katrina in 2005.“We need to think about, how do we support an entire city when a hurricane comes?” she said. “We need to think about how to help our entire city, because guess what? Our blood and our sweat is going to be what it takes to rebuild the city, just like we rebuilt it” after Katrina.Other climate-driven disasters, from heat waves to flooding, are already affecting vulnerable Americans. Late last month, for example, the Oregon Occupational Safety and Health Administration confirmed that a worker on a construction site collapsed June 28, the hottest day on record in the state, and died less than two weeks later. It attributed the death at Robinson Construction to “heat stress.”A separate report released Thursday by the Atlantic Council’s Adrienne Arsht-Rockefeller Foundation Resilience Center said the United States now suffers more than 8,500 excess deaths in a typical year due to extreme heat driven by recent warming. That will increase to nearly 60,000 by 2050, it added, “with populations in Arizona, Southern California and southwest Texas hit hardest.”The lights of Times Square in New York are reflected in standing water Sept 2, 2021, as Hurricane Ida left behind not just water on city streets but wind damage and severe flooding along the Eastern seaboard.Extreme heat has put the United States on track to lose an average of $100 billion a year from lost productivity, the analysis found, with the figure rising to $200 billion by 2030.Dominique Browning, co-founder of the green group Moms Clean Air Force, said the EPA’s report “couldn’t be more perfectly timed,” following Ida’s destructive wake. “We are in such an emergency.”But she added that it remains to be seen whether the Biden administration and Congress will put in place powerful enough legislation and regulation to cut pollution and slow-rising temperatures. The group is pressing the EPA, for instance, to set tougher standards for ozone and soot, two pollutants at higher levels in neighborhoods with more racial minorities.Black people are 40% more likely than other groups to currently live in places where extreme temperatures driven by climate change will result in higher mortality rates, the analysis found. In addition, African Americans are 34% more likely to live in areas where childhood asthma diagnoses are likely to be exacerbated by climate change.EPA staffers launched the study last summer under President Donald Trump, with an eye toward publishing it in an academic journal. But “the Biden-Harris administration took ownership of this report and elevated it,” Goffman said, because of its focus on climate and environmental justice.President Biden issued an executive order a week after taking office aimed at addressing the historic pollution burdens faced by communities of color that were targeted for the construction of railroad depots, coal-fired power plants, freeways and factories that produce toxic chemicals. But he has yet to deliver on some of his most sweeping promises to address historic inequities, as Congress has yet to enact his legislative proposals that would pour billions of dollars into these areas.Low-income residents with no high school diploma — including White people, who like the other groups fall under the environmental justice umbrella of communities historically zoned for pollution — will also experience more flooding and lost work hours from flooding, the analysis said.A passport and other documents are seen water logged on a counter in a basement apartment on 153rd Street in the Flushing neighborhood of the Queens borough of New York, Sept. 2, 2021, in New York.The study “drew on a growing body of literature,” the authors wrote, such as the fourth National Climate Assessment, which “focuses on the disproportionate and unequal risks that climate change is projected to have on communities that are least able to anticipate, cope with, and recover from adverse impacts.”The analysis covers only the Lower 48 states, excluding Alaska and Hawaii. As a result, the authors said, it does not capture the full effect on some groups, including Alaska Natives and Asian Americans.The new study looked at a range of adverse effects based on average global temperatures rising between 1 degree Celsius and 4 degrees Celsius.But global temperature increases are not felt evenly. A 2 degrees Celsius increase worldwide could cause an average annual temperature spike of 3 degrees Celsius in large swaths of the United States, scientists said, including the Great Plains, Midwest, Northeast and Southwest.A worldwide rise of 4 degrees Celsius would cause an average annual spike of up to 6 degrees Celsius in those areas.Black people 65 and older would probably be profoundly affected by poor air quality. They are 41% to 60% more likely to die as a result of fine-particle pollution, or soot, depending on how high temperatures rise.In 49 cities analyzed for the study, from Seattle to Miami, Black people are 41% to 59% more likely to die as a result of poor air quality.Black children 17 and younger would also suffer disproportionately, the study found. They are 34% to 40% more likely to be diagnosed with asthma depending on the range of temperature increases based on where they live.Native Americans and Latinos are more likely to be affected by extreme temperatures where they work. Latinos would be 43% more likely than others to lose work hours and pay because it’s too hot, while American Indians and Alaskan Natives are 37% more likely to lose hours.

The COVID-19 pandemic has created a nurse staffing crisis that is forcing many U.S. hospitals to pay top dollar to get the help they need to handle the crush of patients this summer.The problem, health leaders say, is twofold: Nurses are quitting or retiring, exhausted or demoralized by the crisis. And many are leaving for lucrative temporary jobs with traveling-nurse agencies that can pay $5,000 or more a week.It’s gotten to the point where doctors are saying, “Maybe I should quit being a doctor and go be a nurse,” said Dr. Phillip Coule, chief medical officer at Georgia’s Augusta University Medical Center, which has on occasion seen 20 to 30 resignations in a week from nurses taking traveling jobs.“And then we have to pay premium rates to get staff from another state to come to our state,” Coule said.The average pay for a traveling nurse has soared from roughly $1,000 to $2,000 per week before the pandemic to $3,000 to $5,000 now, said Sophia Morris, a vice president at San Diego-based health care staffing firm Aya Healthcare. She said Aya has 48,000 openings for traveling nurses to fill.At competitor SimpliFi, President James Quick said the hospitals his company works with are seeing unprecedented levels of vacancies.“Small to medium-sized hospitals generally have dozens of full-time openings, and the large health systems have hundreds of full-time openings,” he said.The explosion in pay has made it hard on hospitals without deep enough pockets.Kansas Gov. Laura Kelly lamented recently that the state’s hospitals risk being outbid for nurses by other states that pay a “fortune.” She said Wednesday that several hospitals, including one in Topeka, had open beds but no nurses to staff them.In Kansas City, Missouri, Truman Medical Centers has lost about 10 nurses to travel jobs in recent days and is looking for travelers to replace them, said CEO Charlie Shields.He said it is hard to compete with the travel agencies, which are charging hospitals $165 to $170 an hour per nurse. He said the agencies take a big cut of that, but he estimated that nurses are still clearing $70 to $90 an hour, which is two to three times what the hospital pays its staff nurses.“I think clearly people are taking advantage of the demand that is out there,” Shields said. “I hate to use ‘gouged’ as a description, but we are clearly paying a premium and allowing people to have fairly high profit margins.”In Texas, more than 6,000 travel nurses have flooded the state to help with the surge through a state-supported program. But on the same day that 19 of them went to work at a hospital in the northern part of the state, 20 other nurses at the same place gave notice that they would be leaving for a traveling contract, said Carrie Kroll, a vice president at the Texas Hospital Association.FILE – In this Aug. 18, 2021, photo, a poster honoring medical and frontline workers hangs on a nursing station of an intensive care unit at the Willis-Knighton Medical Center in Shreveport, La.“The nurses who haven’t left, who have stayed with their facilities, they are seeing these other people come in now who are making more money. It provides a tense working environment,” Kroll said.The pandemic was in its early stages when Kim Davis, 36, decided to quit her job at an Arkansas hospital and become a travel nurse. She said she has roughly doubled her income in the 14 months that she has been treating patients in intensive care units in Phoenix; San Bernardino, California; and Tampa, Florida.“Since I’ve been traveling, I’ve paid off all my debt. I paid off about $50,000 in student loans,” she said.Davis said many of her colleagues are following the same path.“They’re leaving to go travel because why would you do the same job for half the pay?” she said. “If they’re going to risk their lives, they should be compensated.”Health leaders say nurses are bone-tired and frustrated from being asked to work overtime, from getting screamed at and second-guessed by members of the community, and from dealing with people who chose not to get vaccinated or wear a mask.“Imagine going to work every day and working the hardest that you have worked and stepping out of work and what you see every day is denied in the public,” said Julie Hoff, chief nurse executive at OU Health in Oklahoma. “The death that you see every day is not honored or recognized.”Meanwhile, hospitals are getting squeezed by the revolving door of departures and new hires from traveling agencies.Coule cited a recent example in which his hospital in Georgia hired a respiratory therapist through an agency to replace a staff member who had decided to accept a traveling gig. The replacement came from the same hospital where his respiratory therapist had just gone to work.“Essentially we swapped personnel but at double the cost,” he said.Patricia Pittman, director of the Fitzhugh Mullan Institute for Health Workforce Equity at George Washington University, said many nurses still harbor resentment toward their employers from the early stages of the pandemic, in part from being forced to work without adequate protective gear.“The nurses say, ‘Hey, if I am not going to be treated with respect, I might as well go be a travel nurse,’” she said. “‘That way I can go work in a hellhole for 13 weeks, but then I can take off a couple months or three months and go do whatever.’”

Americans will likely have to get a third shot of the Pfizer and Moderna vaccines, Dr. Anthony Fauci said Thursday at a White House press briefing.”I must say from my own experience as an immunologist, I would not at all be surprised that the adequate full regimen for vaccination will likely be three doses,” Fauci, who is director of the National Institute of Allergy and Infectious Diseases, told reporters.He said the Food and Drug Administration and the Centers for Disease Control and Prevention would make the final decision.Whether those who got the one-shot Johnson & Johnson will need boosters remains to be seen.Any booster for the Pfizer and Moderna vaccines would be given between five and eight months after the second dose.White House Coronavirus Response Coordinator Jeffrey Zients said that 175 million Americans were now fully vaccinated, an increase of 10 million from a month ago.”That’s a major milestone in our vaccination effort,” Zients said at the briefing.The seven-day rolling average on Thursday of new COVID-19 cases in the U.S. was more than 150,000 per day, while hospitalizations were at 12,000 and deaths at 953, CDC Director Dr. Rochelle Walensky said.Fauci also addressed the so-called mu variant, which the World Health Organization added to its list of variants of interest Monday.”We’re paying attention to it — we take everything like that seriously — but we don’t consider it an immediate threat right now,” said Fauci, who also serves as White House chief medical adviser.First identified in Colombia, mu has been seen in at least 39 countries, WHO said.Some information for this report came from The Associated Press.

U.S. climate envoy John Kerry warned Thursday that Beijing’s coal-building spree could “undo” global capacity to meet environmental targets, after holding talks with top officials in China. Tensions between Beijing and Washington have soared in recent months, with the two sides trading barbs on China’s human rights record and its initial handling of the coronavirus. Tackling climate change is among a handful of issues where the two sides had struck notes of harmony. But Beijing has in recent months emphasized that environmental cooperation could be hurt by deteriorating Sino-U.S. relations. Kerry told journalists Thursday evening that the United States has made it “clear that the addition of more coal plants represents a significant challenge to the efforts of the world to deal with the climate crisis.” FILE – Workers put away equipment after coming out of the Datai coal mine in Mentougou, west of Beijing, Jan. 8, 2020.Chinese plans for new coal plants could “undo the capacity of the world to reach net-zero by 2050,” he said, adding that while they had “very constructive” talks, he also was “very direct” on the topic. Despite pledges to reach peak coal consumption before 2030, then move toward carbon neutrality. China brought 38.4 gigawatts of new coal-fired power into operation last year — more than three times the amount brought online elsewhere in the world. China has challenged the United States to fix relations with Beijing in order to make progress on climate change. Kerry urged the Chinese government, however, not to let environmental cooperation be affected by tensions between the world’s two biggest polluters, calling it a “global challenge.” “It is essential … no matter what differences we have, that we have to address the climate crisis,” he said. Foreign Minister Wang Yi had told Kerry earlier in the visit that cooperation on global warming could not be disentangled from broader diplomacy between the two countries. In a video call with the climate envoy, Wang accused Washington of a “major strategic miscalculation toward China,” according to the ministry statement. “It is impossible for China-U.S. climate cooperation to be elevated above the overall environment of China-U.S. relations,” Wang said. He added that “the ball is now in the United States’ court, and the U.S. should stop seeing China as a threat and opponent.” ‘China can do more’ Kerry visited Japan earlier this week before traveling to the northeastern Chinese city of Tianjin, in a tour aiming to drum up support for a major global summit to tackle pressing climate issues.  FILE – A coal-burning power plant can be seen behind a factory in China’s Inner Mongolia Autonomous Region, October 31, 2010.The 26th edition of the U.N. Climate Change Conference of the Parties — COP26 — in Glasgow in November marks the biggest climate summit since the 2015 Paris negotiation. Kerry said he plans to meet with his Chinese counterparts again before the summit, to push for stronger emission reduction commitments.  The U.S .envoy has repeatedly urged China to step up efforts to reduce carbon emissions. “We have consistently said to China and other countries … to do their best within their given capacity,” Kerry said Thursday. “We think that China can do more.” The country is the world’s current largest emitter of carbon dioxide, followed by the United States, which has historically emitted more than any other nation to date. While Beijing has promised to reach peak carbon emissions by 2030 and become carbon neutral by 2060, it continues to be heavily dependent on coal, which fuels nearly 60 percent of its energy consumption. “We have an opportunity to make a positive impact in Glasgow,” Kerry said. “It really depends on the choices that China makes at this point.”

The Federal Aviation Administration said Thursday that Virgin Galactic cannot launch anyone into space until an investigation is complete into a mishap that occurred during July’s flight with founder Richard Branson.The ban came as Virgin Galactic announced plans to launch three Italian researchers to the edge of space in a few weeks.The FAA said the rocketship carrying Branson and five Virgin Galactic employees veered off course during its descent back to New Mexico on July 11. The deviation put the ship outside the air traffic control clearance area.The FAA is overseeing the probe; it’s responsible for protecting the public during commercial launches and reentries. Crew safety, on the other hand, is outside its jurisdiction. Virgin Galactic insisted Thursday that Branson and everyone else on board were never in any added danger.”Virgin Galactic may not return the SpaceShipTwo vehicle to flight until the FAA approves the final mishap investigation report or determines the issues related to the mishap do not affect public safety,” the FAA said in a statement.Virgin Galactic acknowledged the space plane dropped below the protected airspace for 1 minute and 41 seconds. The spacecraft’s free-flying portion of the up-and-down flight lasted about 15 minutes and reached an altitude of 53.5 miles (86 kilometers).Virgin Galactic said high-altitude wind caused the change in flight path and insisted the two pilots “responded appropriately.” In a statement, the company said the flight was “a safe and successful test flight that adhered to our flight procedures and training protocols.””At no time were passengers and crew put in any danger as a result of this change in trajectory,” the company noted.Branson beat fellow billionaire Jeff Bezos — founder of Amazon and the rocket company Blue Origin — into space by nine days. Bezos launched July 20 with three others from West Texas.Virgin Galactic and Blue Origin are vying to sell seats to tourists, scientists and anyone else looking to experience a few minutes of weightlessness. Virgin Galactic’s rocketship is launched from an airplane, while Blue Origin’s capsule is hoisted by a reusable New Shepard rocket.Virgin Galactic is aiming for late September or early October for its next flight, with two Italian Air Force officers, an engineer for the National Research Council of Italy, Virgin Galactic’s chief astronaut instructor and the rocketship’s two pilots. It will be the company’s first launch where researchers accompany their own experiments. The company plans to start flying ticket holders next year.Blue Origin has yet to announce a date for its next passenger flight, other than to say it will be soon.

The European Center for Disease Prevention and Control has issued a report saying that based on current evidence, there is no urgent need for COVID-19 vaccine booster shots and the public health focus should remain on getting initial vaccinations to eligible European citizens.The report added additional doses should be considered for those individuals with compromised immune systems who did not respond adequately to their initial dose or doses.But the report says the available current evidence regarding the “real world” effectiveness and duration of protection provided by all the vaccines authorized for use in the European Union shows they are highly protective against COVID-19-related hospitalization, severe disease and death. COVID-19 is caused by the coronavirus.The report also noted that European nations should consider what administering boosters might do regarding the availability of vaccines for nations outside the EU, which continue to struggle with obtaining and administering enough initial doses for their populations.France Wednesday became the first EU nation to start administering booster shots to people over 65, and to those with underlying health conditions as a guard against the delta variant of the coronavirus. Spanish health authorities are considering similar action.(Some information in this report come from the Associated Press.)

The World Health Organization warns few governments are providing necessary care for many of the more than 55 million people living with dementia at a time when this debilitating brain condition is growing rapidly around the world.A stock-taking analysis of WHO’s 2017 Global Action Plan on Dementia shows few states are implementing measures for caring and treating people living with this condition.It finds only a quarter of countries worldwide have a national policy or plan for supporting people with dementia and their families.  It warns too many governments are unprepared to deal with this growing public health problem, which affects 55 million people globally – more than 60 percent in low-and-middle-income countries.The World Health Organization estimates the number of people with dementia will rise to 78 million by 2030 and an estimated 139 million by 2050.  WHO estimates the global cost of dementia also is expected to balloon from the present $1.3 trillion to $2.8 trillion by 2030.Technical Officer in WHO’s Department of Mental Health and Substance Use, Katrin Seeher, said too many countries lack a basic comprehensive policy to respond to the challenges that lie ahead.“We also need to strengthen the health and the social care system in countries to ensure that there is universal access to dementia diagnosis but also to treatment and care.  And we especially need to reduce the gap that exists between high-income and low-and-middle income countries and between urban and rural areas,” said Seeher.Dementia is caused by a variety of diseases and injuries that affect the brain, such as Alzheimer’s disease or stroke. It mainly afflicts people over the age of 60 and can affect memory, other cognitive functions, and make it difficult to perform everyday tasks.Tarun Dua is Unit Head of WHO’s Department of Mental Health and Substance Use. While there is no cure, she said reducing risk factors can potentially prevent up to 40 percent of dementia cases.“For example, healthy diet. Looking at the risk factors, which are the same risk factors for noncommunicable diseases, such as tobacco use or harmful use of alcohol.  Managing conditions like hypertension, diabetes, or depression—social isolation.  These are the things that we can do promote our brain health and decrease the cognitive decline and the risk for dementia,” said Dua.WHO reports people with dementia require primary health care, specialist care, community-based services, rehabilitation, long-term care, and palliative care. Health officials note dementia is not a normal part of aging.  But countries must be prepared to support and care for the increasing numbers of people that will be afflicted with this disabling condition in the years to come.

After suspending the use of 1.63 million doses of the Moderna COVID-19 vaccine over contamination concerns last week, Japan is now recalling those doses, Moderna Inc. and its Japanese partner, Takeda Pharmaceutical Co. Ltd. said Wednesday.Last week, some vials of the vaccine were found to be contaminated with stainless steel.Japanese officials said Wednesday that they did not think the stainless steel particles posed a health risk, while Moderna said the contamination was probably caused by pieces of metal rubbing together in the machinery that puts stops on the vials.”Stainless steel is routinely used in heart valves, joint replacements and metal sutures and staples. As such, it is not expected that injection of the particles identified in these lots in Japan would result in increased medical risk,” Takeda and Moderna said in a joint statement.According to Taro Kono, the Japanese minister overseeing vaccinations, around 500,000 people received shots from the suspended Moderna batches.The focus on the contaminated doses was heightened after two men died within days of receiving second doses from the contaminated batches.While their deaths are still being investigated, Moderna and Takeda said there was no evidence the vaccine played a role in their deaths.”The relationship is currently considered to be coincidental,” the companies said in the statement.(Some information in this report comes from Reuters.)

A new report released Wednesday by the United Nations indicates extreme weather events have increased fivefold over the past 50 years, while the number of fatalities related to those events has dropped.Officials from the U.N.’s weather and climate agency, the World Meteorological Organization, introduced the report during a briefing from the agency’s headquarters in Geneva. The report shows weather-related disasters have occurred on average at a rate of one per day over the past five decades, killing 115 people and causing $202 million in losses daily.Mami Mizutori, U.N. special representative for disaster risk reduction, told reporters she found the report “quite alarming.” She noted that this past July was the hottest July on record, marked by heat waves and floods around the world. The study shows that more people are suffering due to this increased frequency and intensity of weather events.Mizutori said 31 million people were displaced by natural disasters last year, almost surpassing the number displaced by conflicts. She said on average, 26 million people per year are pushed into poverty by extreme weather events. Now, the COVID-19 pandemic is compounding the problem.The U.N. disaster risk specialist said, “We live in this, what we call, the multihazard world, and it demonstrates that we really need to invest more in disaster risk reduction and prevention.”WMO Secretary-General Petteri Taalas said the good news in the report is that during that same period, fatalities related to these disasters dropped by nearly three times, due to early warning systems and improved disaster management.But the study also shows that more than 91% of the deaths that do occur happen in developing or low-income countries, as many do not have the same warning and management systems in place.The WMO officials said the economic losses associated with these disasters will worsen without serious climate change mitigation. Taalas said if the right measures are put in place, the trend could be stopped in the next 40 years. WMO called on the G-20 group of world economic powers to keep their promise to reduce greenhouse gas emissions.Some information for this report was provided by The Associated Press, Reuters, and Agence France-Presse.

The World Health Organization has designated a new strain of COVID-19 as a “variant of interest.”The global health agency announced in its weekly bulletin Tuesday that Mu, also known by its scientific designation B.1.621, has been detected in South America and Europe since it was first identified in Colombia in January.The WHO said the Mu variant has several characteristics that make it more resistant to vaccines, but said more studies needed to be conducted to fully understand how it works.The Mu variant is the fifth one designated by the WHO as a variant of interest.  Four other variants have been designated as “variants of concern,” including alpha, which has been detected in 193 countries, and the more transmissible delta, which is present in 170 countries and has been linked to the current worldwide surge of new infections.Scientists in South Africa announced earlier this week they have detected a new COVID-19 variant designated C.1.2.  The variant has spread across Africa, Asia, Europe and the southern Pacific region of Oceania since it was first spotted in South Africa in May.The variant has not been identified by the WHO as either a variant of interest or variant of concern.Dr. Rochelle Walensky, the director of the U.S. Centers for Disease Control and Prevention, on Tuesday urged Americans who have not received a COVID-19 vaccine to avoid traveling during the upcoming Labor Day holiday weekend due to a surge of new infections and deaths driven by the delta variant.  The United States is averaging well over 100,000 new COVID-19 cases per day, with states like Florida, Mississippi and Washington state reporting record levels of new cases and hospitalizations.Meanwhile, two key officials in the U.S. Food and Drug Administration’s vaccine review office are leaving their posts in the coming weeks. Dr. Marion Gruber, the director of the division, is retiring in October, while her deputy, Dr. Philip Krause, will leave the following month.  The retirements of Gruber and Krause come at a crucial time for the FDA, which is nearing a decision on whether to recommend COVID-19 vaccines for children under 12 years old and booster shots of the current vaccines already approved for the adult Americans.Wenderson Cerisene, 7, right, and his sister Dorah, 9, wait to get tested for COVID-19, Aug. 31, 2021, in North Miami, Florida. Florida schools are seeing a rise in COVID-19 cases forcing of students and teachers to quarantine.The New York Times reports Gruber and Krause are upset over the Biden administration’s recent announcement that booster shots would be offered for some Americans beginning next month, well before the FDA had time to properly review the data.In Australia, Premier Daniel Andrews of Victoria state says authorities will gradually lift the current coronavirus restrictions once 70 percent of its adult residents have received at least one dose of a coronavirus vaccine.  Victoria and its capital city, Melbourne, have been under a strict lockdown since early August due to an outbreak that began back in June, but Andrews says it is now apparent that it was time to switch to a mass vaccination strategy to bring the outbreak under control.“We were aiming to drive it down and have cases falling, it is now the advice of the experts that that is not possible, so now we have to contain the growth of cases and the speed at which they increase,” Andrews told reporters.  He said the state should reach 70 percent vaccination by September 23.Victoria state posted a record 120 new cases on Wednesday, including two deaths.  (Some information for this report came from the Associated Press, Reuters and AFP.)
