Two new COVID-19 subvariants, collectively nicknamed FLiRT, are increasingly edging out the winter's dominant strain ahead of a possible summer uptick in coronavirus infections.
The new FLiRT subvariants, officially known as KP.2 and KP.1.1, are believed to be roughly 20% more transmissible than their parent, JN.1, the winter's dominant subvariant, and are combining to make up a large percentage of coronavirus infections nationally, according to disease experts. |
