Health professionals warn there may be a spike in Covid-19 cases this summer.
Cases of the FLiRT variants, "whose label derives from the names of the mutations in the variants' genetic code," according to CNBC, are rising in the U.S. and Europe.
The variants are descendants of the JN.1 variant, and the dominant strain of the grouping is KP.2, which accounted for "28.2% of all cases in the two weeks to May 11, up from 3.8% at the end of March, shortly after the strain was first discovered," according to CNBC.
In addition to masking in public spaces and staying up-to-date with your vaccinations, which experts often recommend during spikes in Covid cases, it may be helpful to bolster your immune system.

"You can't just say, 'Well, I'll be good in the winter and bad in the summer.' It doesn't work that way. It disrupts cells and takes them a long time to get back to their normal pattern of behavior."
