If a bat ever is in a room with you, get a rabies vaccine ASAP. Even if you think it wasn't even close to you. Rabies has no cure and the vaccine only works within a certain time frame.

If you start showing symptoms like fear of water it is already too late, only one teenage girl was ever cured of it and extraordinary measures were taken like an induced coma and massive antivirals, she still didn't fully recover.

I know this stuff because I got to work with bats once but didn't come close to touching them, just the bags they were in. My partner is fully vaccinated and has prophylactic shots every year or two because she actually gets bitten by them often (apparently the rabies infected ones are a lot more bitey than uninfected ones).
