COVID-19 variant KP.3.1.1 predominant in U.S. as infections rise

The KP.3.1.1 COVID-19 variant circulating in the United States, has been causing increasing infections in the country, the latest data from the U.S. Centers for Disease Control and Prevention (CDC) showed. KP.3.1.1, of the Omicron family, is among many currently co-circulating JN.1-derived variants in the U.S.

The rise in prevalence of KP.3.1.1 comes as markers of COVID-19 activity, including test positivity, emergency department visits and hospitalizations, remain elevated, particularly among adults aged 65 years and older and children younger than 2 years. The CDC recommends that the public get COVID-19 vaccines to protect against serious illness from COVID-19.
