A man awoke to a bat on his neck and declined a vaccine. Weeks later, he died of rabies.

Animals that have rabies tend to be aggressive, Austin said, and could also show symptoms such as fever, excessive drooling, seizures and more. Not all animals with rabies will foam at the mouth, though some will if the disease is in a more advanced stage. Bats infected with rabies might exhibit odd behavior, such as staying awake during the day or being unable to fly.
