Back in the fall they were predicting a trifecta - a combination of Covid, flu, and RSV. People have been saying for years that "Covid is just like the flu", which it isn't, but there are similarities in the symptoms. Maybe this time it's the flu instead of Covid. Which reminds me, my wife and I were visiting the grandkids and got sick after we got back. We tested negative Tuesday morning and should probably test again. I don't think it's anything significant, just part of the childhood germ factory cycle.
