Strongyloidiasis is a human parasitic disease caused by the nematode (roundworm) Strongyloides stercoralis, or sometimes S. fĂĽlleborni. It can cause a number of symptoms in people, principally skin symptoms, abdominal pain, diarrhea and weight loss. In some people, particularly those who require corticosteroids or other immunosuppressive medication, Strongyloides can cause a hyperinfection syndrome that can lead to death if untreated. The diagnosis is made by blood and stool tests. The drug Ivermectin is widely used in the treatment of strongyloidiasis. It is thought to affect 30–100 million people worldwide, mainly in tropical and subtropical countries. Worldwide efforts are aimed at eradicating the infection in high-risk groups. Strongyloidiasis was first described in France in 1876. (An OSH glossary used in safety and health at work which is, adopted by ILO {102}..
