It has been asserted that evidence of pre-Columbian hookworm has been found in the Americas, specifically in Peru, Brazil, and Tennessee. However, based on an analysis of the life cycle and morphology of hookworm, the paleopathologic indications for the presence of hookworm infestation in the Americas prior to 1492 are suspect. It is concluded that the material found in the Peruvian mummy is probably pinworms, that the Brazilian and Tennessee materials are probably not hookworm, and, therefore, that hookworm was one of many pathogens brought to the Americas after contact in 1492.
