@minxdragon I've done it twice (two dif ppl /sigh) and dodged covid twice. My person has also done it in a different house twice.
The covid+ person kept in their room with a good air purifier next to them. I handled the rest of the house, would make food, leave it on a tray outside their door and they'd mask up and pick it up.
I masked everywhere except my office and bedroom, where I was also running good air purifiers.
