Human strongyloidiasis is a parasitic disease caused by infection with the helminth Strongyloides stercoralis. It is included in WHO’s list of neglected tropical diseases within the group of soil-transmitted helminthiases. Widespread throughout the tropics, S. stercoralis infects an estimated 300–600 million people worldwide.

Strongyloidiasis has a wide range of clinical presentations, ranging from subclinical disease to diarrhoea, abdominal pain and urticaria, potentially leading to deadly complications due to hyperinfection and disseminated disease, especially in immunocompromised individuals.
