Prevalence and perception of schistosomiasis in irrigated rice field area in Mali.

Summary The aim of this work was to assess prevalence and clinic of schistosomiasis as well as the knowledge, attitude and practice (KAP) of populations living in the village of Molodo, a rice irrigated area of Mali. By cross sectional survey with a single passage, we enrolled 346 children aged of 7 to 14 years and 308 parents. The prevalence of Schistosoma haematobium and S. mansoni were respectively 72% and 68%. Micro-hematuria (Sy=86%; Sp=45%), urinary difficulty (Se=828% ; Sp=33%), high frequency of urine (Se=76% ; Sp=31%) and suspubians pain (Se=78% ; Sp=31%) associated with urinary schistosomiasis indicated that these symptoms could be relevant diagnosis signs. Similar observations could be considered as a good sign of diagnosis of intestinal schistosomiasis due to S. mansoni with abdominal pains (Se=75% ; Sp=36%), to have a fancy of stool (Se=75% ; Sp=32%), diarrhea (Se=71% ; Sp=32%), des conjunctival paleness (Se=85,% ; Sp=33%) et de spleen enlargement (Se=71% ; Sp=33%). The transmission patterns of schistosomiasis were not well known by populations, because only 15% of pupils and 38% of parents incriminated the canal and/or the 'fala" (the lake) as genitourinary bilharzias contamination source especially after bathing. The intestinal form was known by 11% of pupils and by 24% of parents. These results show that in spite of schistosomiasis endemic pattern, in this area, populations didn't know well this pathology.
