How can I get schistosomiasis?
A test has been performed on your blood; when this test is positive, it means you have been infected with schistosomiasis at some point in your past. Because the parasite can live for many years, if you have not been treated for schistosomiasis in the past, this means you are very likely to still be infected. Other tests (stool or urine samples) can sometimes diagnose this infection as well.
