Strongyloidiasis in children five years and below

Strongyloidiasis is one of the major human intestinal infections caused by a minute nematode, Strongyloides stercoralis. It is a soil-transmitted nematode of worldwide distribution, which resides in the small intestines of humans and is acquired by tissue penetration by the infective stage, filariform larva, of the worm. In the immunocompetent hosts, Strongyloides stercoralis infects only the mucosal of the small intestines and persists as an asymptomatic often chronic infection. In contrast, in the presence of immune suppression it has ability to multiply within the human host, known as hyperinfection. Its occurrence has been reported more commonly among adults.
