How does schistosomiasis affect the body?
Schistosomiasis can affect many parts of the body, including the intestines, liver, bladder, and lungs. The parasites can cause inflammation, scarring, and organ damage over time.
How do schistosomes enter the body?

The prognosis for schistosomiasis depends on early diagnosis and appropriate treatment. With treatment, most people recover fully and have a good long-term outlook.
What is the best way to avoid schistosomiasis?
The best way to avoid schistosomiasis is to avoid swimming or bathing in contaminated water. Other prevention measures include wearing protective clothing and footwear when in infested waters and ensuring good sanitation practices.
How does praziquantel treat schistosomiasis?
Praziquantel works by paralyzing the parasites’ muscles, causing them to release their hold on tissue surfaces and die within the body.
