2539- Can't predict if Omicron will become dominant variant in US: Fauci

White House chief medical adviser Anthony Fauci said it could not yet be predicted if the Omicron COVID-19 variant will become the dominant variant in the US. "It's unlikely that the country would impose additional travel restrictions," Fauci added. Earlier, the US had restricted travel from South Africa, Botswana, Zimbabwe, Namibia, Lesotho, Eswatini, Mozambique and Malawi over the new strain.
