They are the natural reservoir for the Marburg virus, and Nipah and Hendra viruses, which have caused human disease and … A dead host is literally a dead end for a virus, so a virus wants to hit the "sweet spot" where it can reproduce as much as possible without killing the host too quickly or making him too sick to spread it around.
