FLiRT variants are offshoots of the JN.1 variant — all part of the broader Omicron family — that caused this winter’s wave. The mutations of the FLiRT variants make increased transmissibility — and a possible summer wave — a real threat. “We learned from the laboratories that FLiRT variants appeared, so far, to be as transmissible as the other Omicron subvariants, which means they’re really quite contagious. As of May 1, the requirement for all hospitals to report Covid-19 data to the federal government has expired. While the FLiRT variants pose some risk this summer, experts remain focused on what might happen in the fall.
