I’m just taking a SWAG here, but I would bet that the contraction of rabies by bats from animals other than bats is probably statistically pretty low. Probably even lower than that of other mammals. Most bats probably get rabies from other bats - that’s the downside of living in huge colonies and tight living quarters. According to one of the local bat-ologists here in Austin Texas (where we have a huge population of bats and they are generally well regarded because we have a tiny population of flying insects), the incidence of rabies in the bat population is less than 2%. Considering the way they live, I’d say this is staggeringly low. The problem is that if you see a bat on the ground there’s a high probability that he’s sick, so you don’t want to take a chance with them.
Other related observations. Many people are afraid of bats because they think all bats are blood sucking parasites - which, of course, is technically paranoia since most bats (especially in North America) are not. The fewer people that are insightful enough to know that most bats are not of the vampire variety, still fear bats with a certain paranoia because of a ‘believed’ high incidence of rabies (which apparently way overinflated). Finally, people don’t really fear rabies… it’s the cure for rabies that scares the hell out of most folks!
