The BA.2 sub-variant of Omicron is estimated to make up 85.9% of the coronavirus variants in the United States as of April 9, the U.S. Centers for Disease Control and Prevention (CDC) said on Tuesday.

A resurgence in COVID-19 cases in parts of Asia and Europe has raised concerns that another wave could follow in the United States, but the country’s health experts believe it is unlikely.
