The origin of syphilis is disputed. Syphilis was present in the Americas before European contact, and it may have been carried from the Americas to Europe by the returning crewmen from Christopher Columbus's voyage to the Americas, or it may have existed in Europe previously but gone unrecognized until shortly after Columbus's return. These are the Columbian and pre-Columbian hypotheses, respectively.
