Columbus Voyage Tied to Syphilis Spread?
Date:12/28/2011

WEDNESDAY, Dec. 28 (HealthDay News) -- A new examination of the origin of syphilis supports the theory that the sexually transmitted disease was carried to Europe aboard Christopher Columbus' ships as they sailed home from the New World.

The disease was not spread through sexual contact at the time, but adapted to survive once it got to Europe, Emory University researchers say.

"Syphilis has been around for 500 years," study co-leader Molly Zuckerman, a former Emory graduate student who is now an assistant professor at Mississippi State University, said in an Emory news release. "People started debating where it came from shortly afterwards, and they haven't stopped since. It was one of the first global diseases, and understanding where it came from and how it spread may help us combat diseases today."

After analyzing skeletal evidence in 54 published reports, the researchers found that syphilis did not exist in Europe until after Columbus' historic voyage to the New World in 1492. They said that most of the skeletal material lacked characteristics that would meet standard diagnostic criteria for chronic syphilis, such as small holes on the skull and long bones.

It appears that skeletons previously considered evidence of syphilis in Europe before Columbus' trip were dated incorrectly because of seafood consumption, which would have altered the collagen levels of the skeletons, the researchers said.

Their appraisal is published in the Yearbook of Physical Anthropology.

"This is the first time that all 54 of these cases have been evaluated systematically," said study co-author George Armelagos, an anthropologist at Emory, in the news release. "The evidence keeps accumulating that a progenitor of syphilis came from the New World with Columbus' crew and rapidly evolved into the venereal disease that remains with us today."

The researchers suggested someone sailing with Columbus brought '/>"/>
