Substantial progress has been made during the past decade to prevent and control schistosomiasis (also known as bilharziasis) globally. Over 200 million people worldwide are infected with over 700 million people living at risk of infection. Before the introduction of safe oral drug therapy (e.g., praziquantel and oxamniquine), snail control for prevention of Schistosoma transmission was an important component of many regional schistosomiasis control programs (Fig 1). Locations sampled for Biomphalaria pfeifferi snails and of 3 primary schools where children were tested for intestinal schistosomiasis in the region of Lake Malawi, Africa. The thin female resides in the gynecophoral canal of the thicker male. Symptoms include abdominal pain, diarrhea, bloody stool, or blood in the urine. We infected laboratory-bred snails with S. mansoni miracidia and examined cercarial shedding to determine susceptibility and resistance. Progress is mainly due to large-scale periodic treatment of affected populations with praziquantel, the only medicine recommended by the World Health Organization (WHO) against all forms of schistosomiasis. microorganisms.”. The cercariae enter the human body on contact with the skin and develop into adult worms. Credit: DPDx, Treatment resources for Health Professionals. Centers for Disease Control and Prevention.
