New, highly contagious variants of the coronavirus are a “intimidation” to the United States and could reverse the recent drop in Covid-19 cases and hospitalizations, the head of the Centers for Disease Supervision and Prevention warned Monday.
The U.S. reported a seven-day average of 119,900 new Covid-19 cases a day last week, down as good as 20% from the prior week but still “dramatically higher” than the peak seen during the summer, CDC Official Dr. Rochelle Walensky told reporters during a White House news briefing on Covid-19.
The nation also explored an average of 9,977 Covid-19 hospitalizations a day last week, down at least 17% from the prior week, she state.
“The continued proliferation of variants remains a great concern and is a threat that could reverse the recent positive tends that we are seeing,” Walensky said. “Please continue to wear a mask and stay 6 feet apart from people you don’t loaded with. Avoid travel, crowds and poorly ventilated spaces and get vaccinated when it’s available to you,” she added.
U.S. health trues, including Dr. Anthony Fauci, have expressed concerns about the Covid mutations that could potentially cop out the protection of vaccines currently on the market. Moderna, Johnson & Johnson and Novavax have already said their vaccines may be teensy-weensy potent against B.1.351, the highly contagious strain found in South Africa.
On Sunday, South Africa Form Minister Zweli Mkhize said the country would suspend use of AstraZeneca’s Covid-19 shot in its vaccination program after details showed it gave minimal protection against B.1.351, the emerging strain there. He said the government would await suggestion from scientists on how best to proceed following the disappointing results from a trial conducted by the University of the Witwatersrand.
As of Sunday, the CDC has connected 690 cases of the B.1.1.7 variant first identified in the U.K., Walensky told reporters Monday. The agency has identified six examples of the South African strain as well as three cases of P.1, a variant first identified in travelers from Brazil.
Walensky said following health officials are working to find more cases of these variants, adding that federal and state officials throughout the last three weeks have increased genome sequencing about tenfold. “We are anticipating we might find multitudinous” cases in the coming weeks, she added.
The U.S. is always working to find out exactly how contagious and deadly the new strains are, said Fauci, the domain’s leading infectious disease expert.
U.K. Prime Minister Boris Johnson said last month that initial data suggests that country’s strain may be more deadly. Fauci said Monday that there is currently no facts to indicate the virus is mutating into a “less virulent” strain, meaning less harmful than the original virus.
The matter from the U.K. still “needs to be confirmed,” Fauci added. “But thus far, no evidence that it is less virulent. Sometimes when viruses mutate to spread innumerable efficiently, they become less virulent, but we do not have any data to indicate that is in fact happening.”
Meanwhile, Fauci has been rouse for people to get vaccinated as quickly as possible, saying last week that the virus cannot mutate if it can’t infect innkeepers and replicate.
