Bogotá, Colombia – New archaeological evidence is rewriting the history of syphilis, a sexually transmitted infection long associated with the 15th-century voyages of Christopher Columbus. Researchers have uncovered skeletal remains in the Bogotá savanna dating back centuries before European contact, exhibiting signs of the disease. This discovery suggests that syphilis, or a closely related treponemal infection, was present in the Americas long before its introduction to Europe, challenging established narratives about its global spread.
The findings, spearheaded by the Colombian Institute of Anthropology and History (ICANH), center around the analysis of human remains unearthed in the region. These remains display characteristic bone lesions indicative of treponematosis, a group of diseases caused by the bacterium Treponema, which includes syphilis, bejel, and yaws. The identification of these lesions predates the arrival of Europeans in the Americas, prompting a reevaluation of the disease’s origins and transmission routes. The research underscores the importance of interdisciplinary approaches – combining archaeology, paleopathology, and historical analysis – to understand the complex history of infectious diseases.
For centuries, the prevailing theory attributed the rapid spread of syphilis across Europe following Columbus’s voyages to the disease being brought back by sailors from the Americas. This narrative, popularized by Italian physician and poet Girolamo Fracastoro in the 16th century, depicted the disease as a “French disease” or “Neapolitan disease,” reflecting its perceived origins and spread. Fracastoro, as noted by Britannica, even crafted a poetic account of the disease, naming it after the mythological shepherd Syphilus, who was afflicted by a divine punishment.
Though, the Colombian findings, and growing evidence from other archaeological sites, are challenging this long-held belief. Researchers are now considering the possibility that different strains of treponemal diseases existed in both the Old and New Worlds, and that the European outbreak may have been a re-emergence of a previously existing, but less virulent, strain. As Wikipedia details, Fracastoro himself was a pioneer in germ theory, proposing that diseases were caused by transferable “spores” – a concept remarkably ahead of its time.
The ICANH research team meticulously examined skeletal remains, identifying specific bone changes consistent with treponemal infections. These changes, often manifesting as porous lesions on the skull and long bones, provide a tangible record of the disease’s presence in past populations. Further analysis, including ancient DNA studies, is underway to determine the precise strain of Treponema involved and its relationship to modern syphilis. This work is crucial for understanding the evolutionary history of the bacterium and its adaptation to different human populations.
The discovery also sheds light on the pre-Columbian health landscape of the Bogotá savanna. It suggests that infectious diseases were a significant factor influencing the health and well-being of indigenous populations long before European contact. Understanding these pre-Columbian disease patterns is essential for a more complete and nuanced understanding of the region’s history and the impact of colonization on indigenous health.
Whereas the exact mechanisms of transmission for these ancient treponemal infections remain unclear, researchers believe they likely differed from the primarily sexually transmitted route of modern syphilis. The conditions of pre-Columbian life, including close communal living and potentially different hygiene practices, may have facilitated the spread of the disease through non-sexual contact. Further research is needed to unravel the complexities of transmission in these ancient populations.
The ongoing research in Colombia promises to continue reshaping our understanding of syphilis and its global history. Future studies will focus on expanding the archaeological record, conducting more detailed genetic analyses, and exploring the social and cultural contexts of the disease in pre-Columbian societies. This work will not only refine our understanding of the past but also inform our approach to combating sexually transmitted infections today.
What comes next involves a broader investigation of skeletal remains across the Americas to determine the geographic distribution and prevalence of ancient treponemal infections. Researchers are also exploring the potential for identifying ancient DNA from other sources, such as coprolites (fossilized feces), to gain further insights into the disease’s evolution and spread. The implications of these findings extend beyond historical understanding, potentially informing the development of new diagnostic tools and treatment strategies.
