It's curious right? I had to persist on my search as, it appeared to me, the focus of what is out there about bats and diseases is on the fact that they are massive pathogens reservoirs. But then I found something which made for an interesting reading Ref..

In a nutshell some of the causes of death in urban European bats were found to be:

1. Trauma (with young and female bats being more susceptible to this especially in the maternal season).
2. Bacterial infection as a consequence of attacks by cats.
3. Viral infection (a very low incidence of infection by lyssavirus and herpesvirus was found).
4. Parasite infestation.

An interesting observation is that it appears that bats are more likely to succumb to (bacterial and viral) infections when they are already in a state of debilitation (e.g. due to injury).

So, there you go!
I wish you & the family a very good day 😊
