The BA.2 sub-variant of Omicron was estimated to be 34.9% of the coronavirus variants circulating in the United States as of March 19, the US Centers for Disease Control and Prevention (CDC) said on Tuesday.

COVID-19 infections in the United States have receded sharply since hitting record levels in January, although a coronavirus resurgence in parts of Asia and Europe due to the BA.2 sub-variant has raised some concerns.
