Hookworm larvae live in the soil and infect humans by penetrating the skin. The worms travel to the lungs in the bloodstream and from there pass via the windpipe and gullet to the small intestine. Heavy hookworm infestations may cause considerable damage to the wall of the intestine, leading to a serious loss of blood; this, in conjunction with malnutrition, an provoke severe anemia. Symptoms include abdominal pain, diarrhea, debility, and mental inertia. The disease occurs throughout the tropics and subtropics and is prevalent in areas of poor personal hygiene and sanitation.
