@Mona104 Airbnb can't help you with this, it's something you need to deal with. Your guest is violating local regulations. If I were in your shoes, I'd tell him that if he doesn't stop ignoring the rules the govt. has put in place, he needs to leave your home immediately. If he kicks up a fuss, gets nasty, or just ignores you, report him to your local health authorities. Also report him to Airbnb, tell them that he is violating govt. emergency rules and putting you, your home and the community at risk and that you need to cancel the rest of his reservation with no penalties to you and he needs to leave your home immediately.
