Schistosomiasis

Schistosomiasis is transmitted through contact with contaminated freshwater, where the infective larvae of the parasite penetrate the skin of individuals engaging in activities such as swimming, fishing, or washing clothes. Once inside the body, the larvae develop into adult worms, which reside in the blood vessels surrounding the intestines or bladder, depending on the species. Chronic infection can lead to severe complications, including liver and spleen enlargement, bladder cancer, and neurological disorders. Control strategies for schistosomiasis typically involve mass drug administration with praziquantel, improved sanitation and access to clean water, and educational campaigns to promote behavior change and reduce transmission risk.
