FLiRT variants, including KP.2, are new members of the SARS-CoV-2 family that have emerged in the U.S., possibly leading to an increase in cases.
Topol emphasizes it's uncertain whether FLiRT variants will cause a major surge, noting current low virus levels in U.S. wastewater and declining hospitalizations.
Despite the potential for an uptick in cases due to KP.2 and related variants, Topol predicts it may not manifest as a significant wave of infections, attributing this to possible immunity from prior JN.1 infections.
