I'll chime in again, although I think I did re: a similar post.
It's not so much the physical proximity, it's the bodily fluids. I don't see how sleeping in 2 beds, no matter how close they are together...it's most likely the possibility of overnight sweating. The same for any of the bodily fluids...Sure, I am concerned about anyone around me and chose to hibernate for 3-5 days...One could say that's too much, but I think about...shopping?...sure, I can be 6 feet away, but what I touch the cashier touches, monies exchanged, handling food you may put back on the shelf, a cough in the wrong direction, etc.
Use common sense, but I think you might be too fearful of it...in the car, just have your husband wear a mask, be fully clothed and wear nitrile gloves...When he pees, just don't miss...and flush twice. Hospitals know the parameters, they'll deal with the ancillary equipment.
You'll be fine!! Keep us informed!
