The U.S. will speak Friday with scientists from South Africa to “get the facts” on the emerging, heavily mutated Covid-19 variant detected there in a small number of samples, White House chief medical advisor Dr. Anthony Fauci told CNN’s “New Day.”

Reviewing South Africa’s research will help the U.S. better understand whether the novel B.1.1.529 variant can evade the antibody protection against the virus provided by vaccines and previous infection, Fauci said. With countries across Europe and Asia imposing travel restrictions on several nations in southern Africa, Fauci added that analyzing the data could help determine whether similar measures might also be necessary in the U.S.

“This is really something that’s in motion,” Fauci said. “And we just arranged, right now, a discussion between our scientists and the South African scientists a little bit later in the morning to really get the facts because you’re hearing a lot of things back and forth.”

Fauci emphasized that the U.S. is in “very active communication” with South African scientists, and is working to get the molecular makeup of the variant in order to conduct lab tests.

The new strain has now been detected in a growing number of countries, including Belgium, Botswana and Israel. Fauci said there was “no indication” that B.1.1.529 had reached the U.S. yet.

B.1.1.529 contains even more mutations than the world’s most dominant Covid strain, the highly transmissible delta variant. The new variant features roughly 50 mutations according to data presented by the South Africa Department of Health at a media briefing Friday. That includes more than 30 mutations to the spike protein that allows Covid to enter cells and 10 to the receptor binding domain that first makes contact with cells.

Comparatively, the delta strain has just two mutations to the receptor binding domain.
