A number of dozen instances of the new Omicron variant of the coronavirus have been recognized in the USA, a quantity that’s “more likely to rise,” Dr. Rochelle P. Walensky, the director of the Facilities for Illness Management and Prevention, mentioned on Sunday on ABC’s “This Week.”

At least 17 states have detected cases, together with in some people who have no known history of recent travel abroad, which specialists have mentioned suggests community spread of the variant in the USA.

Genetic sequencing is required to find out which variant an contaminated affected person has. In latest months the USA has greatly expanded sequencing efforts, however the course of takes time. The C.D.C., for example, usually takes about 10 days to yield outcomes. In keeping with Dr. Walensky, about 14 % of all constructive P.C.R. assessments in the USA are being sequenced.

“What we don’t but know is how transmissible will probably be, how properly our vaccines will work, whether or not it should result in extra extreme illness,” Dr. Walensky mentioned.

American officers are in frequent communication with specialists in South Africa the place the variant is now widespread, Dr. Anthony S. Fauci, the nation’s main infectious illness physician, mentioned Sunday on CNN’s “State of the Union.”

How rapidly Omicron will unfold in the USA, the place the extremely contagious Delta variant now accounts for 99.9 % of all instances, stays unknown, Dr. Fauci mentioned. “What’s going to occur when you have got these two competing with one another?” he mentioned, including that, “we’ve actually bought to watch out” in assessing how extreme Omicron may find yourself being.

A new report from South Africa has fueled hopes that the variant might not trigger severe illness, although it stays far too early to conclude that, specialists say. The report focuses totally on 42 sufferers in a hospital in Gauteng province, the center of the nation’s Omicron outbreak.

Though the researchers weren’t capable of verify that each one the instances have been attributable to Omicron, nearly all of sufferers with the virus didn’t require supplemental oxygen, the report says, and plenty of weren’t hospitalized for Covid-19 itself. As an alternative they examined constructive for the virus after being admitted for different causes.

“This can be a image that has not been seen in earlier waves,” wrote Dr. Fareed Abdullah, who directs the Workplace of AIDS and TB Analysis on the South African Medical Analysis Council and is the writer of the brand new report.

However the findings include main caveats, together with the actual fact the sufferers have been youthful than throughout earlier waves, and thus much less more likely to have extreme illness.

On Monday, the United States will begin requiring all incoming air travelers to point out proof of a negative test taken the day before departure, no matter their vaccination standing or citizenship.

On Sunday, officers additionally defended the government’s ban on vacationers from eight international locations in southern Africa. The ban has been criticized for being each unhelpful and overly punitive.

“That ban was finished at a time once we have been actually in the dead of night,” Dr. Fauci mentioned, noting that it was meant to purchase officers time to assemble extra details about Omicron. However now that extra data is coming in from around the globe, officers are regularly re-evaluating the ban, he mentioned.

“Hopefully, we can raise that ban inside a fairly affordable time period,” he mentioned, including that “all of us really feel very badly concerning the hardship” that it placed on southern Africa.

However officers dismissed the potential for home journey restrictions, noting that they might be impractical. “That might be extraordinarily onerous for people who find themselves making an attempt to get across the nation for issues like holidays,” Dr. Francis S. Collins, the Nationwide Institutes of Well being director, said on NBC’s “Meet the Press” on Sunday. “And I don’t know the way a lot we’d achieve by it.”
