What’s the difference between patient 1 and patient 0?

Question

I know this is probably a stupid question, but if patient 0 is the first person to be infected, then why aren’t they just patient 1?

Answer 1

Apparently it was actually a [Patient “O”](https://en.wikipedia.org/wiki/Index_case), not zero. The man, Gaëtan Dugas from “o”utside of California, was discovered to not even be the original case of AIDS. Someone misread the investigator’s notes and created the “Patient Zero” name.
