Necator americanus is an intestinal nematode parasite that infects humans. It belongs to the family Ancylostomatidae and subfamily Bunostominae. There are two main species of hookworms that commonly infect humans, Ancylostoma duodenale and Necator americanus, which are thought to infect 800 million people worldwide. Hookworms have a life cycle where infective larvae penetrate the skin, usually on the feet, and develop into adult worms in the small intestine where they feed on blood and can cause anemia.
