A new set of COVID-19 variants, nicknamed FLiRT, is rising in prevalence in the United States.
The variant, labeled KP.2, made up about 25% of the COVID-19 cases in the U.S. in April, according to USA Today. That rise makes it the new dominant variant in the country, surpassing JN.1.
"The CDC is tracking SARS-CoV-2 variants KP.2 and KP.1.1, sometimes referred to as 'FLiRT,' and working to better understand their potential impact on public health," the agency said in an emailed statement to USA TODAY in May.
