The FLiRT family of Covid-19, including the dominant KP.2 variant, now accounts for about 25% of infections in the US.

Two new FLiRT variants are emerging with the potential to evade immunity, raising concerns about a possible summer surge.

Early observations indicate the FLiRT variants could be more infectious and capable of reinfecting individuals with vaccine or natural immunity.

There is an indication of higher hospitalization rates with FLiRT variants, but no increased risk of death has been reported.

Symptoms of FLiRT variants align with those of previous Covid-19 strains, such as sore throat, cough, and fatigue.

The World Health Organization has labeled FLiRT as a variant of interest and calls for continued monitoring and vaccination efforts.

Experts, including Dr. Sushila Kataria, advocate for enhanced testing, focused vaccinations, and adherence to preventive measures like social distancing and hand hygiene.

Public health recommendations to combat the spread of FLiRT variants include social distancing, hand washing, masking, staying current with vaccinations, and following CDC guidelines for isolation if symptomatic.
