WHAT IS STRONGYLOIDIASIS?
Strongyloidiasis is a chronic human parasitic infection mainly caused by Strongyloides stercoralis, a soil-transmitted helminth (STH) capable of persisting in the human host for decades through a unique autoinfection cycle. This ability allows larvae to reinvade the host without external re-exposure, making strongyloidiasis fundamentally different from other STH infections and a major reason it often remains undetected for years.
Globally, strongyloidiasis was estimated to affect 613.9 million people in 2017, with the highest burden reported in tropical and subtropical regions. The South-East Asia, African, and Western Pacific regions together accounted for approximately 76.1% of global infections.
Many infected individuals develop chronic, asymptomatic infections that may persist for decades – or even a lifetime – because of the parasite’s ability to autoinfect. Of particular concern is the risk of progression to hyperinfection syndrome or disseminated strongyloidiasis following immunosuppression, especially with corticosteroid therapy. Therefore, screening for Strongyloides infection is recommended before initiating immunosuppressive therapy in individuals at risk of infection.

WHO ARE AT HIGHER RISK OF SEVERE DISEASE
(HYPERINFECTION/DISSEMINATED STRONGYLOIDIASIS)?
IMMUNOSUPPRESSED INDIVIDUALS
- Patients infected with human immunodeficiency virus (HIV) or human T-lymphotropic virus type 1 (HTLV-1)
- Patients receiving chemotherapy for cancer
- Solid organ transplant recipients
- Hematopoietic stem cell (bone marrow) transplant recipients

- Patients with autoimmune or inflammatory diseases receiving immunosuppressive drugs (e.g. rheumatoid arthritis)
- Patients with severe malnutrition or other causes of impaired cellular immunity
PATIENTS RECEIVING CORTICOSTEROID THERAPY
Both short-term and long-term systemic corticosteroid therapy
can increase the risk of Strongyloides hyperinfection syndrome
PATIENTS WITH HAEMATOLOGICAL MALIGNANCIES
- Leukemia
- Lymphoma and other haematological malignancies
