Hookworm infection is a parasitic infection caused by helminths of the Nematode class. The two main species that infect humans are Necator americanus and Ancylostoma duodenale.
Epidemiology[edit]
Hookworm infection is common in tropical and subtropical regions of the world where sanitation is poor and people often walk barefoot. It is estimated that up to 740 million people worldwide are infected with hookworm.
Life cycle[edit]
The life cycle of hookworms begins with the release of eggs in the feces of an infected person. These eggs hatch in the soil and develop into larvae, which can penetrate the skin of a human host. Once inside the body, the larvae migrate to the lungs, are coughed up and swallowed, and then reach the small intestine, where they mature into adult worms.
Symptoms and complications[edit]
Most people with hookworm infection have no symptoms. However, heavy infections can cause a range of symptoms including abdominal pain, diarrhea, loss of appetite, weight loss, fatigue and anemia. In children, chronic hookworm infection can cause growth retardation and cognitive impairment.
Diagnosis[edit]
Hookworm infection is diagnosed by finding hookworm eggs in a stool sample. Other diagnostic methods include serological tests and endoscopy.
Treatment[edit]
The treatment for hookworm infection is antihelminthic medication, such as albendazole or mebendazole. Iron supplements may also be given to treat anemia.
Prevention[edit]
Prevention of hookworm infection involves improving sanitation, wearing shoes, and avoiding contact with soil that may be contaminated with human feces.
