CDC: BA.2, an omicron subvariant, now makes an estimated 23% of new cases in the U.S.

The omicron BA.2 subvariant now makes up an estimated 23.1% of all COVID-19 cases in the U.S., according to data published Tuesday by the Centers for Disease Control and Prevention. That means the number of people getting infected with this subvariant has increased from the week before, when the CDC said BA.2 made up an estimated 13.7% of new cases. The BA.2 subvariant has been designated a variant of concern by the World Health Organization and "appears inherently more transmissible than BA.1," the organization said in February. BA.1, another subvariant of omicron, made up an estimated 66.1% of all cases in the U.S., while omicron is 10.8% of all cases, according to data gathered for the week ending March 12.
