The fast-spreading Omicron subvariant XBB.1.5 accounted for nearly half of the COVID-19 cases in the United States, data from the U.S. Centers for Disease Control and Prevention showed on Friday.

It is estimated to have accounted for 49.1% of COVID cases in the country in the week ended Jan. 21, compared with 37.2% estimated last week.
