I saw a squirrel just keel over and fall out of a tree the other day. He was wearing a mask.
I heard that the squirrels were immune! You can’t ever even catch those guys.
Just as an aside, if you take someone to the hospital during a pandemic they will be triaged. If they are admitted, that is the last time you will see them until it is over, they are released, or they are dead.
You wont be allowed in, and you wont be allowed to visit.
So, take that worry off your list. ;-)
