I just listened to Alan Alda's pocast interviewing Eric Topol about the COVID pandemic.

Interesting research being done on Long COVID. He says that 10s of Millions of Americans are probably experiencing it.

Also, the virus often finds a long-term home in the upper respiratory locations.

I wonder if we will find that the body has learned to compartmentalize pockets of the virus in the nasal cavities and just a little bit escapes to cause a low-grade battle that causes long-COVID.
