The Biden administration has put a well-known Russian paramilitary organization on a list of religious freedom violators alongside a number of notorious terrorist organizations.

The World Health Organization is renaming monkeypox as mpox, citing concerns the original name of the decades-old animal disease could be construed as discriminatory and racist.

The World Health Organization is holding an open forum to rename the disease monkeypox, after some critics raised concerns the name could be derogatory or have racist connotations.

British health authorities say the monkeypox outbreak across the country may be peaking and that the epidemic’s growth rate has slowed.

ANN ARBOR – New research from the University of Michigan shows that reinfections of seasonal coronaviruses are common, suggesting that the virus behind COVID-19 could be endemic. “The frequency of reinfections with the different seasonal coronaviruses suggests that SARS-COV-2 is not going to completely disappear.”AdThe researchers used data on 3,418 individuals from the Household Influenza Vaccine Evaluation from the years 2010-2018. Upon evaluating the data, the team found 1,004 seasonal coronavirus infections. Additionally, 27 percent of the reinfections occurred within one year of the initial infection, which researchers say is a relatively short period of time given the virus’ seasonal nature. “In our study, participants had high levels of anti-spike protein binding antibody to seasonal coronaviruses, but these antibodies did not correlate with protection from infection,” Petrie said in a release.

The briefing comes as states begin lifting virus restrictions as COVID vaccinations ramp up, and as some states -- like Michigan, New York and New Jersey -- experience another surge in virus spread. The nation has also just cleared President Biden’s goal of administering 100 million vaccinations within his first 100 days in office. President Biden is also assembling the next big White House priority, a sweeping $3 trillion package of investments on infrastructure and domestic needs.

The Food and Drug Administration has approved Johnson & Johnson’s COVID-19 vaccine for an emergency use authorization. Fauci, who is the director of the National Institute of Allergy and Infectious Diseases, said people should take the single-shot Johnson & Johnson COVID-19 vaccine if that’s what they are offered. Instead, the J&J vaccine uses a harmless, weakened cold virus to carry instructions into the body to trigger the immune response and a method developed a decade ago and used for an ebola vaccine.

My whole world is turned upside-down.”The global death toll was approaching 2.5 million, according to Johns Hopkins. While the count is based on figures supplied by government agencies around the world, the real death toll is believed to be significantly higher, in part because of inadequate testing and cases inaccurately attributed to other causes early on. Despite efforts to administer coronavirus vaccines, a widely cited model by the University of Washington projects the U.S. death toll will surpass 589,000 by June 1.

(White House via AP)WASHINGTON – The nation's top infectious disease expert doesn't want the Super Bowl to turn into a super spreader. Dr. Anthony Fauci, says when it comes to Super Bowl parties during the pandemic, people should “just lay low and cool it.”He said during TV interviews Wednesday that now isn’t the time to invite people over for watch parties because of the possibility that they’re infected with the coronavirus and could sicken others. Big events like Sunday’s game in Tampa, Florida, between the Kansas City Chiefs and the Tampa Bay Buccaneers are always a cause for concern over the potential for virus spread, Fauci said. “You don't want parties with people that you haven’t had much contact with,” he told NBC's “Today” show. "You just don’t know if they’re infected, so, as difficult as that is, at least this time around, just lay low and cool it.”The NFL has capped game attendance at 22,000 people because of the pandemic and citywide coronavirus mandates.

Vaccines are not yet approved for children, but testing already is underway for those as young as 12. If those trials are successful, Dr. Anthony Fauci said they would be followed by another round of testing down to those 9 years old. “Hopefully by the time we get to the late spring and early summer we will have children being able to be vaccinated,” Fauci said at a White House coronavirus briefing. Ad“You don’t want to have to ... go through an efficacy trial, where you’re involving tens of thousands of children," Fauci explained. Testing in the U.S. had a chaotic start, and experts say in many parts of the country it's still subpar.

The mutated version of the virus, first identified in South Africa, was found in two cases in South Carolina. Neither of the people infected has traveled recently, the South Carolina Department of Health and Environmental Control said Thursday. AdIn South Carolina, the state health agency said the variant was found in one person from the state's coastal region and another in its northeastern corner. The variant first found in South Africa was detected in October. Biden on Monday reinstated COVID-19 travel restrictions on most non-U.S. travelers from Brazil, the U.K. and South Africa.

He said the variant strain is something “to follow very carefully” and “we’re looking at it very intensively now.”He said: “Does it make someone more ill? Fauci spoke on CNN's “State of the Union.”

(NIAID-RML via AP)Two new studies give encouraging evidence that having COVID-19 may offer some protection against future infections. Researchers found that people who made antibodies to the coronavirus were much less likely to test positive again for up to six months and maybe longer. The institute's study had nothing to do with cancer — many federal researchers have shifted to coronavirus work because of the pandemic. One is a blood test for antibodies, which can linger for many months after infection. Only 0.3% of those who initially had antibodies later tested positive for the coronavirus, compared with 3% of those who lacked such antibodies.

U.S. government officials are putting an early end to a study testing an Eli Lilly antibody drug for people hospitalized with COVID-19 because it doesn’t seem to be helping them. Independent monitors had paused enrollment in the study two weeks ago because of a possible safety issue. In a statement Lilly notes that the government is continuing a separate study testing the antibody drug in mild to moderately ill patients, to try to prevent hospitalization and severe illness. The company also is continuing its own studies testing the drug, which is being developed with the Canadian company AbCellera. Lilly and Regeneron have asked the U.S. Food and Drug Administration to grant emergency use authorization for their drugs for COVID-19 while late-stage studies continue.

The paused study, called ACTIV-3, started in August and aims to enroll 10,000 hospitalized COVID-19 patients in the United States, Denmark and Singapore. The pause in the Lilly study comes a day after a temporary halt to enrollment in a coronavirus vaccine study. Johnson & Johnson executives said Tuesday that it will be a few days before they know more about an unexplained illness in one participant that caused a pause in its late-stage vaccine study. Johnson & Johnson isn’t disclosing the nature of the illness. He says Johnson & Johnson gave information on the case to the independent monitoring board overseeing the safety of patients in the study, as the research protocol requires.

President Donald Trump is pushing for a faster timeline, which many experts say is risky and may not allow for adequate testing. FDA Commissioner Stephen Hahn pledged that career scientists, not politicians, will decide whether any coronavirus vaccine meets clearly stated standards that it works and is safe. In one of the largest studies yet, Johnson & Johnson aims to enroll 60,000 volunteers to test its single-dose approach in the U.S., South Africa, Argentina, Brazil, Chile, Colombia, Mexico and Peru. J&J’s vaccine is made with slightly different technology than others in late-stage testing, modeled on an Ebola vaccine the company created. Going forward, “we need uniformity throughout the country.”In a testy exchange, Sen. Rand Paul of Kentucky insisted public health officials were wrong that a lockdown could change the course of the pandemic.
