About 735 cases of a coronavirus variant that emerged in New York City in November have now been identified in the U.S., including 585 in the last two weeks, a federal health official said.
The mutation has traveled extensively through the metropolitan New York region, and individual cases have also been found in 14 other states, including Texas, Wyoming and Maryland, according to Gregory Armstrong, director of the Centers for Disease Control and Prevention’s Advanced Molecular Detection Program.
