[Treatment of bilharziasis].

Specific treatment of bilharziosis is obviously simplified by praziquantel which, unfortunately, is not easily available in endemic areas. Nevertheless, the major problem is an early treatment before the occurrence of severe sequellae. Mass chemoprophylaxis remains needed and, if possible, with praziquantel. For economic purposes, we have often to use either oxamniquine or niridazole-metrifonate combination.
