Schistosomiasis in Malawi--a review.

Prevalence data for schistosomiasis in Malawi, collected in recent years, indicated that the infection, especially Schistosoma mansoni is far more widespread than was previously thought. S. haematobium is highly prevalent in the south, while S. mansoni predominates on the Central Plateau. Both infections occur with moderate to high intensity along the lakeshore plain. Despite the high prevalence, reports of morbidity due to the infection are fewer than might be expected.
