Sorry to read that, logtroll. Things don't look good for your MIL. That's a very bad situation, what with nobody to take care of her. I'm pretty sure my mother actually died in early April from Covid-19. No testing was done and she was hospitalized with salmonella, but that was a time when nobody was especially careful about SARS-COV2 infection. She was 92.

I say probably, because I think she gave it to me, and then I gave it to my wife. Salmonella doesn't work that way.

If she does get sick, hopefully somebody can take her to get medical care. Or at least call the EMTs.
