Strongyloidiasis

Strongyloidiasis is an intestinal infection caused by the roundworm Strongyloides stercoralis. Unlike most parasites, this worm can reproduce inside the human body, meaning an untreated infection can persist for decades. It is widespread across humid, tropical regions including Southeast Asia, South Asia, and parts of the Pacific.

Who is at risk and how it spreads

The worm lives in warm, moist soil and enters the body through bare skin, most often the feet. Rural communities, agricultural workers, and travellers in Thailand, Indonesia, the Philippines, and India face heightened exposure. People with weakened immune systems, including those on long-term corticosteroids, are at risk of hyperinfection, a severe form where larvae spread beyond the gut.

Recognising and treating strongyloidiasis

Many infections cause no obvious symptoms for years. When symptoms do appear they typically include a moving, itchy rash at the entry site, abdominal discomfort, bloating, and intermittent diarrhoea. Hyperinfection can produce fever, cough, and severe gastrointestinal distress.

Treatment relies on ivermectin, which clears the infection effectively in a short course. It sits within the broader class of antiparasitic medicines. Anyone who suspects hyperinfection or who develops respiratory symptoms alongside gut symptoms should seek medical attention promptly.
