Syphilis likely started as a zoonotic disease (from animals like cattle or sheep) that jumped to humans, evolving into its venereal form and causing a major epidemic in Europe after Columbus's voyages, but recent genomic evidence strongly suggests the bacteria circulated in the Americas for millennia before being brought to Europe, possibly as a different Treponema strain (yaws or bejel) that mutated into the highly virulent syphilis we know today, becoming a sexually transmitted infection during that Columbian Exchange.

Why did people lose their noses with syphilis?

People lost their noses to syphilis because the advanced, untreated infection caused destructive lesions (gummas) that ate away at the nasal cartilage and bone, leading to a collapse of the nasal bridge, known as a saddle nose deformity, a hallmark of tertiary syphilis or congenital syphilis. This severe damage, sometimes seen in history, was preventable with timely treatment but resulted in permanent disfigurement, breathing problems, and often required reconstructive surgery.
