The variant, called KP.2, now makes up the largest share of new infections in the U.S.

Disease experts anticipate a small uptick in Covid cases this summer, as a new variant spreads.

The KP.2 variant represents 28% of Covid infections in the U.S., up from just 6% in mid-April, according to data released Friday by the Centers for Disease Control and Prevention.

KP.2 became dominant at the end of April — meaning it accounts for the largest share of new cases — outpacing the JN.1 variant, which took over in the winter.
