Causes and risk factors
Helminthiasis is caused due to intestinal parasitic worms. Various worms like Ascaris lumbricoides, Trichuris trichiura, Necator americanus, and Ancylostoma duodenale, etc., cause the infection. The parasite harbors into the human body. A person infected with these parasites passes eggs in the feces. Open defecation causes contamination of the soil with the eggs of the parasite. Accidentally, contamination with food or raw vegetables causes the entry of parasite into the human body. The eggs are hatched into larva in the small intestine and they grow into adult worm. The adult worm then lays eggs which are passed through the feces into the environment and thus a new cycle continues. Contamination of the infected soil with food or working in soil or infected dirt areas causes transmission of the organism. Immune compromised people, old people, and children whose immunity is yet to build up completely are at high risk for developing the infection. The infection is more prevalent in areas where there is poor sanitation and in warm climate areas.
