Rabies started as a natural virus, likely originating in bats, that became a feared, ancient disease, transmitted through animal bites, particularly dogs globally and bats in the Americas, attacking the nervous system and causing fatal brain inflammation, with its history documented from ancient texts and its modern understanding evolving through discoveries by scientists like Louis Pasteur.

How did rabies originally start?

Current theories agree that the lyssaviruses probably originated in Old World bats (Banyard et al., 2014; Kuzmin et al., 2011; Rupprecht et al., 2011; Hayman et al., 2016), which are confirmed reservoir hosts for 14 of the 16 known viral species.

Why is rabies afraid of water?

Rabies patients fear water (hydrophobia) because the virus attacks the brain, causing excruciatingly painful, involuntary spasms in the throat muscles when trying to swallow liquids, even just thinking about them. This isn't a psychological fear of water itself, but a physical reaction to the choking pain, forcing them to avoid drinking, which paradoxically helps the virus spread through their saliva.

Yes, you likely need a rabies shot (post-exposure prophylaxis or PEP) if a bat was in your house, especially if anyone was sleeping, a child, or an impaired person was present, or if there was any direct contact (bite, scratch, even waking up with it in the room), because bat bites can be tiny and missed; contact your health department and doctor immediately to arrange for the bat to be tested and to start PEP if exposure is suspected.
