Hookworms are small, parasitic worms that live in the intestines of humans and animals. They attach themselves to the intestinal wall and feed on blood, which can lead to anemia and other health issues. These worms are typically transmitted through contaminated soil, where their larvae can penetrate the skin, often through bare feet. Infections with hookworms are more common in tropical and subtropical regions, where sanitation may be poor. Preventing hookworm infections involves practicing good hygiene, such as wearing shoes outdoors and ensuring proper sanitation. Treatment usually includes medications like albendazole or mebendazole to eliminate the worms from the body.
