Necator americanus infection

A *Necator americanus* infection is a soil-transmitted parasitic helminthiasis caused by the nematode *Necator americanus*, commonly referred to as the New World hookworm Transmission primarily occurs when infectious third-stage filariform larvae in contaminated soil penetrate human skin, subsequently migrating through the bloodstream and lungs into the small intestine, where adult worms attach to the mucosa using cutting plates Although initial percutaneous invasion may produce localized prurit...

Transmission primarily occurs when infectious third-stage filariform larvae in contaminated soil penetrate human skin, subsequently migrating through the bloodstream and lungs into the small intestine, where adult worms attach to the mucosa using cutting plates Although initial percutaneous invasion may produce localized pruritus and transient pulmonary symptoms during larval transit, the primary clinical hallmark of chronic intestinal infection is gastrointestinal blood loss caused by adult wor...

Although initial percutaneous invasion may produce localized pruritus and transient pulmonary symptoms during larval transit, the primary clinical hallmark of chronic intestinal infection is gastrointestinal blood loss caused by adult worms feeding on host blood and tissues

In moderate to severe infections, particularly among young children and pregnant individuals in resource-limited tropical and subtropical environments, this sustained blood and protein loss leads to microcytic hypochromic iron-deficiency anemia, hypoalbuminemia, malnutrition, and impaired growth or cognitive development
