Strongyloides stercoralis is an intestinal nematode of humans. It is prevalent throughout the tropical, subtropical and temperate regions. It is endemic in hot and humid climates as well as resource poor countries with inadequate sanitary conditions. The rise of international travel and immigration has a positive impact in strongyloidiasis. Man is infected by filariform larvae of Strongyloides stercoralis. Due to its unique auto infection life cycle, Strongyloides may lead to chronic infections remaining undetected for decades. Strongyloidiasis is most often asymptomatic but it has a wide range of clinical presentations.
