No idea. We do grocery pick up and wipe them down. Leave mail for days and wash hands after handling etc. He does work at a hospital. We run an air purifier with uv light. We'll be as careful as we can. I wiped down everything after he went to the room.

The AC/heater is off, but we do have a good filter installed. Forgot what they are called, but I posted about it a few months ago.
