A panel of U.S. health advisers on Tuesday narrowly backed a closely watched COVID-19 pill from Merck, setting the stage for a likely authorization of the first drug that Americans could take at home to treat the coronavirus.  A Food and Drug Administration panel voted 13-10 that the drug's benefits outweigh its risks, including potential birth defects if used during pregnancy.  The recommendation came after hours of debate about the drug's modest benefits and potential safety issues. Experts backing the treatment stressed that it should not be used by anyone who is pregnant and called on the FDA to recommend extra precautions before the drug is prescribed, including pregnancy tests for women of child-bearing age.  The vote specifically backed the drug for adults with mild-to-moderate COVID-19 who face the greatest…

Herd immunity is when a significant portion of a community is immune to an infectious disease, making it harder for the disease to spread. ...

The top U.S. infectious disease expert said Tuesday that vaccinated Americans have "some degree of protection" against the new omicron variant of the coronavirus, but that scientists will not know for a few weeks how vaccines may need to be altered to best fight it.  Dr. Anthony Fauci, President Joe Biden's top medical adviser, said at a White House coronavirus news briefing that the omicron "mutation profile is very different from other variants" of the coronavirus.  While he said the three existing vaccines used in the U.S. could prevent people who have been inoculated from getting seriously ill from the omicron variant, it "remains uncertain … speculative" whether they will fully work against people getting sick.  "We believe it is too soon to tell about the severity" of the omicron…

Japan and France confirmed their first cases of the new variant of the coronavirus on Tuesday as countries around the world scrambled to close their doors or find ways to limit its spread while scientists study how damaging it might be. The World Health Organization has warned that the global risk from the omicron variant is “very high” based on early evidence, saying it could lead to surges with “severe consequences.” French authorities on Tuesday confirmed the first case of the omicron variant in the French island territory of Reunion in the Indian Ocean. Patrick Mavingui, a microbiologist at the island’s research clinic for infectious diseases, said the person who has tested positive for the new variant is a 53-year-old man who had traveled to Mozambique and stopped in South…

U.S. President Joe Biden says a highly transmissible COVID-19 variant, dubbed omicron, is a cause for "concern, not panic" and defended his much-criticized decision to restrict travel from the southern African region, where it was first reported.

The World Health Organization says renewed efforts to prevent the spread of the coronavirus is needed as scientists scramble to determine the risks posed by the new omicron variant. Low vaccine rates combined with public fatigue over safety measures are putting more people in Africa at risk. Experts say it’s no surprise a new variant of the coronavirus has been discovered. Fewer than 8 percent of Africans are vaccinated against COVID-19, creating an environment for the illness to spread and mutate. Dr. Mary Stephen is a technical officer for the World Health Organization’s Africa office.  She said in the absence of vaccines, the public needs encouragement to uphold other measures to reduce the spread and save lives. “We cannot be tired; we have to continue to make sure we are…

Zimbabwe's government says the country is very prepared to handle the new COVID-19 variant - omicron - first reported in neighboring South Africa. The World Health Organization says a fourth wave of the pandemic is most likely to hit Africa. Zimbabwe’s Vice President Constantino Chiwenga – who doubles as the country’s health minister - has asked the nation not to be concerned about omicron. “The country should not panic because we are very prepared. The ramping up of our vaccination program in the past month has seen marked increase in the vaccination uptake. That is the prevention which we are going to have for our people if any other variant comes. At least when your body is protected it is much better than when you are found naked,” said the…

Dutch health officials said Sunday 13 people who recently arrived in the Netherlands on flights from South Africa have tested positive for the new omicron variant of the coronavirus. The passengers were part of a group of 61 who tested positive following their arrival in Amsterdam on Friday. The announcement came shortly after Australia said two cases of the variant were discovered in passengers who recently arrived in Sydney. Omicron is the fifth WHO-designated variant of concern. It was first detected recently in South Africa, which has seen an exponential rise in COVID-19 cases. There are about 30 mutations on the coronavirus' spike protein, and scientists worry that some of them could make the virus easier to transmit. But scientists do not yet know whether omicron is in fact more…

The new potentially more contagious omicron variant of the coronavirus popped up in more European countries on Saturday, just days after being identified in South Africa, leaving governments around the world scrambling to stop the spread. The U.K. on Saturday tightened its rules on mask-wearing and on testing of international arrivals after finding two cases. New cases were confirmed Saturday in Germany and Italy, with Belgium, Israel and Hong Kong also reporting that the variant has been found in travelers. In the U.S., Dr. Anthony Fauci, the government’s top infectious diseases expert, said he would not be surprised if the omicron variant was already in the United States, too. “We have not detected it yet, but when you have a virus that is showing this degree of transmissibility ... it…

The United States praised South Africa on Saturday for quickly identifying the latest coronavirus variant, omicron, and sharing this information with the world. Secretary of State Antony Blinken spoke with South Africa's international relations and cooperation minister, Naledi Pandor, and they discussed cooperation on vaccinating people in Africa against COVID-19, the State Department said in a statement. "Secretary Blinken specifically praised South Africa’s scientists for the quick identification of the omicron variant and South Africa’s government for its transparency in sharing this information, which should serve as a model for the world," the statement said. First detected in South Africa, the omicron variant of the coronavirus that causes COVID-19, was deemed by the World Health Organization a “variant of concern” on Friday. Earlier Saturday, Pandor’s office issued a statement saying…

France is willing to discuss autonomy for the French Caribbean territory of Guadeloupe if it is in the interests of the people who live there, government minister Sebastien Lecornu said. Guadeloupe and the nearby French island of Martinique have seen several days of protests against COVID-19 measures that have spilled over into violence. Lecornu, the minister for France's overseas territories, said in a YouTube video issued late on Friday that certain elected officials in Guadeloupe had raised the question of autonomy, changing its status as an overseas region. "The government is ready to talk about this. There are no bad debates, as long as those debates serve to resolve the real everyday problems of people in Guadeloupe," he said. That was one of a series of initiatives he said the…

Federal health regulators say an experimental COVID-19 pill from Merck is effective against the virus, but they will seek input from outside experts on risks of birth defects and other potential problems during pregnancy. The Food and Drug Administration posted its analysis of the pill ahead of a public meeting next week where academic and other experts will weigh in on its safety and effectiveness. The agency isn’t required to follow the group’s advice. The FDA scientists said their review identified several potential risks, including possible toxicity to developing fetuses and birth defects that were identified in studies of the pill in animals.  Given those risks the FDA will ask its advisers next Tuesday whether the drug should never be given during pregnancy or whether it could be made available…

The world’s largest vaccine maker, the Serum Institute of India has resumed exports of coronavirus vaccines to COVAX the partnership that is distributing vaccines to developing countries. The resumption of exports comes at a critical time when a new variant found in South Africa is causing concern around the world. India suspended exports of vaccines in March this year following a severe surge in infections during the second wave of the COVID-19 pandemic as it used its stocks to ramp up its domestic inoculation program. The first shipments went out Friday. “This will go a long way in restoring vaccine supply equality in the world,” Serum Institute chief executive Adar Poonawalla said on Twitter. The company said in a press statement that said that it expects the supply of vaccines…

With hunting season under way, wildlife agencies in the northeastern U.S. states of New Hampshire and Vermont have started testing for COVID-19 in white-tailed deer, as antibodies for the virus have been found in deer in other states, according to a government study. “We collected blood samples this year during the five busiest days of the hunting season,” said Dan Bergeron, the deer biologist with the New Hampshire Fish and Game Department. “We have biologists at biological check stations and collect ages and weights annually. This year, we also had them collect blood samples.” New Hampshire and Vermont were approached by the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service about testing the white-tailed deer population as part of its national research on the spread of COVID-19 among…

As the world grapples with the emergence of the new highly transmissible variant of COVID-19, worried scientists in South Africa — where omicron was first identified — are scrambling to combat its lightning spread across the country. In the space of two weeks, the omicron variant has sent South Africa from a period of low transmission to rapid growth of new confirmed cases. The country’s numbers are still relatively low, with 2,828 new confirmed cases recorded Friday, but omicron’s speed in infecting young South Africans has alarmed health professionals. “We’re seeing a marked change in the demographic profile of patients with COVID-19,” Rudo Mathivha, head of the intensive care unit at Soweto’s Baragwanath Hospital, told an online press briefing. “Young people, in their 20s to just over their late 30s,…

Anxious-looking travelers thronged Johannesburg international airport and stood in long queues on Friday, desperate to squeeze onto the last flights to countries that had just shut their doors to South Africa. Many cut short their holidays, rushing back from safaris and vineyards when Britain announced late Thursday night that all flights from South Africa and its neighbors would be banned the following day. A flurry of nations — including the United States, Canada and several European countries — have followed suit, concerned about the discovery of a new coronavirus variant, renamed omicron, with several mutations fueling an infection resurgence in South Africa. United Kingdom citizen Toby Reid, a 24-year-old trader in London, was camping on Cape Town's Table Mountain with his girlfriend when the ban was announced. "At about 5:30…

Top U.S. infectious disease official Anthony Fauci said Friday that a ban on flights from southern Africa was a possibility and the United States was rushing to gather data on the new COVID-19 variant.    No decision to halt flights had yet been made, he said. The Wall Street Journal, citing people familiar with the matter, said White House officials were discussing potential travel restrictions on southern African countries. Those officials were expected to meet with agency officials Friday afternoon to make a recommendation, the newspaper said, without specifying which agency.    The White House referred to Fauci's earlier comments when asked about the report and declined further comment. Global authorities have reacted with alarm to the new variant, detected in South Africa, with the European Union and Britain among…

South African scientists are scrambling to determine how quickly a newly discovered variant of the coronavirus can spread and if it is resistant to vaccines.  The new strain has led Britain to reimpose flight bans on six southern African countries, which could deal another heavy blow to their economies.  Coronavirus cases are once again on the rise in South Africa.  Amid the spike, several mutations of a new variant called the B 1.1.529 have been detected in the country, Botswana and Hong Kong.  It has sparked concern it could compete with the previously dominant delta variant and trigger another wave of the pandemic. Dr. Michelle Groome is with South Africa’s National Institute for Communicable Diseases. “There's the potential that this could be more transmissible and that this, there is potential…

Like many others in Europe, Switzerland is facing a steep rise in coronavirus cases. But its federal government, unlike others, hasn’t responded with new restrictive measures. Analysts say it doesn't want to stir up more opposition to its anti-COVID-19 policies, which face a crucial test at the ballot box this weekend as critics have grown increasingly loud. On Sunday, as part of the country’s regular referendums, Swiss voters will cast ballots about the so-called “COVID-19 law” that has unlocked billions of Swiss francs (dollars) in aid for workers and businesses hit by the pandemic. The law has also imposed the use of a special COVID certificate that lets only people who have been vaccinated, recovered, or tested negative attend public events and gatherings. If the Swiss give a thumbs-up, the…

With the Northern Hemisphere heading into winter and COVID-19 cases on the rise across Europe and North America, political leaders from Washington to Brussels are struggling to persuade a pandemic-weary public to get vaccinated against the disease that has killed more than 5 million people and sickened hundreds of millions around the world. In the United States, a high-profile push by President Joe Biden to force all businesses with more than 100 employees to require workers to get vaccinated or submit to regular testing is snarled in court challenges. Across Europe this week, protests, some violent, flared as various governments announced that they would implement stricter measures to combat the disease, including many that limit the ability of unvaccinated people to take an active part in public life. Worldwide, countries…

A new report warns that Australia's native wildlife is in the “grip of an unprecedented alien attack.” Experts at the national science agency, the CSIRO, are predicting that much of the country’s unique flora and fauna is in danger of disappearing by 2050 unless urgent action is taken. Nonnative species have invaded Australia and threaten to overrun indigenous plants and animals. Invasive pests include European rabbits, which infest two-thirds of Australia, feral cats, pigs, foxes and cane toads. Introduced species are endangering more than 80% of Australia’s threatened species. A report, Fighting Plagues and Predators: Australia’s Path Towards a Pest and Weed-Free Future, highlights what researchers believe is “a looming wave of new extinctions.” The study was compiled by the CSIRO, the Commonwealth Scientific and Industrial Research Organization, a government agency.…

An expedition to find lost shipwrecks on Australia’s Great Barrier Reef begins Friday. The voyage is part of the Great Reef Census, one of the world’s largest marine citizen science projects. Conservationists estimate there are up to 900 shipwrecks on the Great Barrier Reef, but only 150 have been found. Shallow water in some parts of the reef off northeastern Australia and the region’s susceptibility to storms and cyclones have made seafaring perilous. Volunteers discovered three shipwrecks last year while surveying the world’s largest coral system. The expedition, which ends Dec. 1, is returning to Five Reefs and the Great Detached Reef, remote regions that are rarely visited, to gather more data and hunt for other wrecks. Onboard the boat are conservationists, scientists and a marine archaeologist. Andy Ridley, the…

Cameroon's largest lake, Lake Ossa, has been invaded by Salvinia molesta, an aquatic fern native to Brazil that hinders navigation, makes fishing impossible and blocks water access. To combat the spreading plant, a local aid group is training fishermen to harvest the fern and transform it into organic coal. Florent Tsanga and other fishermen meet twice a week to remove what they can. Since Salvinia molesta invaded Cameroon’s largest lake in 2016, Tsanga’s life has changed for the worse. He said his children do not go to school because of the salvinia. When the lake was good, in the '80s and '90s, he said, the children went to school. But these days, he can't afford it. Lake Ossa is a wildlife reserve that's home to freshwater turtles, crocodiles, manatees and…

European countries expanded COVID-19 booster vaccinations, began plans to get shots to young children and tightened some curbs Thursday as the continent battled a surge in coronavirus cases and concerns about its economic fallout grew. Slovakia went into a two-week lockdown, and the Czech government declared a 30-day state of emergency involving early closure of bars and clubs and a ban on Christmas markets. Germany crossed the threshold of 100,000 COVID-19-related deaths. Europe is at the heart of the latest COVID-19 wave, reporting a million new infections about every two days and now accounting for nearly two-thirds of new infections worldwide. The European Commission proposed Thursday that EU residents would need to have booster shots if they wanted to travel to another country in the bloc next summer without the…
