Bats are also the common wild reservoir for lyssaviruses, like rabies. Bats are not highly susceptible to rabies, and can remain asymptomatic for long periods of time. If you wake up in a room with a bat in it, or if you find a bat in a room with a child, or otherwise disabled person, rabies post-exposure prophylaxis is called for, even if you don't find a scratch, or bite mark.
