How did farming reach the Southern Andes? Through migration or cultural transmission? Our new paper in @nature.com combines ancient DNA, isotopes, archaeology & paleoclimate to reconstruct 2,000+ years of history in Uspallata, Mendoza. www.nature.com/articles/s41... A Thread🧵 (1/25+)

🧬 Two pathogens, one disease. Leprosy cannot be understood as a single-pathogen disease. Understanding this duality is critical for modern case detection, surveillance, and long-term control strategies. A commentary with @nrascovan.bsky.social and @avanzich.bsky.social #Leprosy #OneHealth #aDNA

#MetagenomicsMonday While it's long been assumed that leprosy came to the Americas with Europeans, new evidence shows that Mycobacterium lepromatosis, was already infecting people here long before that, rewriting the history of leprosy's origins in the New World. doi.org/10.1126/scie...

🌎🧬 Leprosy was already endemic in the Americas for 1,000+ years BEFORE Europeans arrived. Scientists analyzed DNA from ~800 samples & found Mycobacterium lepromatosis infecting Indigenous populations centuries before colonization. #Leprosy @marialopopolo.bsky.social @nrascovan.bsky.social

Revelations on the History of Leprosy in the Americas

Leprosy existed in America long before the arrival of Europeans: a new study reveals the history of a neglected pathogen.

Big news in #GlobalHealthHistory today. A species of bacterium that causes leprosy, discovered in 2008 in modern patients, has been proven to have been present in the Americas well before European arrival. More details in 🧵 below: www.science.org/content/arti... #GlobalMiddleAges #histmed #aDNA 🧪
