I agree...A virus, I am told, may mutate during a disease outbreak and might in fact have done so in the current pandemic. I was a comely, strapping bluejacket (LOL) in late 1968 or early 1969 when struck by a flu that might have been of the Kong Kong variety. I don't know if I could have survived it now. Well just out of curiosity, I checked out some of the world's worst pandemics just to get some perspective. I pray COVID-19 (Novel Coronavirus) is not going to be one of them.
Sorry, ReaganGeneration2, my jumping cursor messed up the excerpt from your post.
