The BA.2 version of omicron is now the dominant coronavirus variant in the US, the CDC says.
The BA.2 subvariant of omicron was estimated to be more than half, or 54.9 percent, of the coronavirus variants circulating in the United States as of Saturday, the U.S. Centers for Disease Control and Prevention said on Tuesday.
Despite the rise of the highly transmissible BA.2 subvariant, health experts in the United States believe that a new wave of infections appears unlikely as overall infections are declining from January’s record highs. Last week, top U.S. infectious disease official Dr. Anthony Fauci said that although he does not expect a major surge, he would not be surprised to see a rise in cases owing to the increasing dominance of the BA.2 subvariant.
