Necator americanus

Necator americanus is a type of hookworm that infects humans. It lives in the small intestine, where it attaches to the intestinal wall using its mouthparts and feeds on blood. Infection occurs when people walk barefoot on contaminated soil containing larvae, which enter the skin and mature into worms inside the body. This can cause symptoms like anemia, fatigue, and abdominal discomfort. It is common in regions with poor sanitation and can be treated with antiparasitic medications. Proper hygiene, wearing shoes, and sanitation improvements can help prevent infection.
