WASHINGTON, January 23, 2026 – Forget everything you thought you knew about the origins of syphilis. A groundbreaking analysis of 5,500-year-old DNA reveals the sexually transmitted infection wasn’t brought to Europe by Christopher Columbus, but actually originated in the Americas, predating his voyages by millennia.This revelation dramatically rewrites the history of the disease and challenges long-held assumptions about its global spread.
Ancient DNA Rewrites Syphilis history
New research pushes back the known origins of treponemal diseases-including syphilis-by 3,000 years.
- DNA from ancient skeletal remains in Peru shows evidence of *Treponema pallidum*,the bacteria that causes syphilis,as early as 3500 BCE.
- Previous theories posited that syphilis originated in Europe and was brought to the Americas in 1492.
- The genetic analysis suggests a more complex evolutionary history for the disease, with multiple strains possibly evolving independently.
- Researchers analyzed DNA from individuals buried in the Chilca Valley of Peru, providing a detailed look at ancient health conditions.
- This finding highlights the importance of ancient DNA analysis in understanding the origins and spread of infectious diseases.
Q: When did syphilis actually originate?
A: Evidence now suggests syphilis, or at least related treponemal diseases, existed in the Americas as early as 3500 BCE, thousands of years before its documented appearance in Europe.
For centuries, the prevailing narrative held that syphilis was a “Columbian exchange” disease-a consequence of contact between Europeans and Indigenous populations in the Americas following Columbus’s arrival in 1492. But the new genetic evidence, extracted from the skeletal remains of individuals who lived in the Chilca Valley of Peru, tells a different story. Researchers identified ancient strains of *Treponema pallidum*, the bacterium responsible for syphilis, in these remains, pushing back the earliest known evidence of the disease by a staggering 3,000 years.
