Quick Answer
See the main history page above. The origins of STDs track closely with human migration and urbanization: syphilis from the Americas post-1492, gonorrhea documented since antiquity, HIV from Central Africa ~1920, and herpes predating modern humans entirely.
- Syphilis: Columbian exchange hypothesis best supported by skeletal evidence.
- Gonorrhea: described in Leviticus (Bible) and by Hippocrates.
- HIV: cross-species transmission from chimpanzees in Cameroon ~1920s, spreading via colonial railways.
- Herpes: HSV-2 diverged from chimp virus ~1.6 million years ago.
