Study reveals shocking origin of herpes

A new study out of the University of California, San Diego alleges that genital herpes in humans originated from our ancestors having sex with chimpanzees.

There are two types of herpes: HSV-1 is herpes of the mouth, and HSV-2 is genital herpes. Humans have their own unique version of HSV-1, but not HSV-2, which would have originated in apes.

Approximately one in four Americans has genital herpes.
