Hookworm larvae enter the human body through the skin, so Lawrence visited about 30 outdoor latrine areas in Cameroon, where he confounded the locals by wading through their feces in his bare feet.
Lifecycle of a hookworm Cutaneous larvae migrans. Necatoriasis is caused by N. americanus. N. americanus can be divided into two areas – larvae and adult stage. The third stage larvae are guided to human skin by following thermal gradients. [3] Typically, the larvae enter through the hands and feet following contact with contaminated soil.
Ancylostoma braziliense larvae can cause accidental infection in humans called cutaneous larval migration or creeping eruption, which produces severe itching in the skin. It is the most common skin infection in tropical region, particularly along the beaches of the Caribbean .
The larvae migrate from the lungs up the windpipe to be swallowed and carried back down to the intestine. If humans come into contact with larvae of dog hookworms or cat hookworms, or of certain other hookworms that do not infect humans, the larvae may penetrate the skin. Sometimes, the larvae are unable to complete their migratory cycle in humans.
