Omicron sub-variant BA.2 makes up 72% of COVID variants in U.S. - CDC

The U.S. national public health agency said on Monday the BA.2 sub-variant of Omicron was estimated to account for nearly three of every four coronavirus variants in the country. Overall COVID-19 cases in the United States have dropped sharply after hitting record levels in January, but a resurgence in cases in parts of Asia and Europe has raised concerns that another wave could follow in the United States. The country's health experts, however, believe it is unlikely. The seven-day moving average of U.S. COVID cases was 26,106 as of April 1, marginally lower than 26,309 from a week earlier, as per data from the U.S. Centers for Disease Control and Prevention (CDC).
