The U.S. Centers for Disease Control and Prevention (CDC) said in a recent update that the new COVID-19 variant JN.1 is continuing to spread across the United States, having nearly doubled in the past two weeks or so.
The agency said on Dec. 22 that JN.1 is continuing “to cause an increasing share of infections and is now the most widely circulating variant in the United States,” adding that it’s now about 39 percent to 50 percent of all COVID-19 variants, whereas JN.1 amounted to about 15 percent to 29 percent two weeks ago.
