Abstract

OBJECTIVE: An epidemiological comparative survey aimed at determination of prevalence and focal distribution of Schistosomes infection and intestinal parasites to provide a reference for evaluating the need for community intervention.

METHODS: All children of 14th October Primary School were involved. The children were from 7 villages that lie on the Assahul valley of lbb governorates in Yemen. The total number was 230 with (82%) boys and (18%) girls. Their age was between 5-18 years with a mean of 10.24 +/- 2.6 years. Millipore and modified Kato techniques were adopted to quantify urinary and intestinal Schistosomes eggs. Other ova, larvae, cysts were recorded whenever seen.

RESULTS: It was revealed that there was a Schistosomes infection rate of 37%. The mansoni prevalence was 35%, hematobia was 5% and mixed infections were 3%. Light infection was classified among 17% of all children; moderate infection among 18% and no intense mansoni infection was determined. Whereas in the case of hematobia species, 2% were intense and 3% were light. Intensity in all children was 5% eggs/g feces in case of intestinal bilharzia and 1% egg/10ml urine in case of urinary. With regard to the prevalence of any soil-transmitted parasites, it was found to be 69% (Ascariosis 68%, Trichuriosis 10%). Double infection was found in 10%. Hookworm eggs were not seen. Infection rates with other parasites were as follows: Giardiosis 18%, Amoebiosis 14%, ova of Hymenolepes nana were seen in 13%, Taeniosis affected 13% and E. Vermicularis 1%.

CONCLUSION: Bivariate analysis revealed significant associations between Schistosomes infection with residence near the valley, male sex and frequent water contact activities. No significant association was found with the age of the child, parents' education, availability of latrine or household standpipe water. In conclusion, schistosomosis was moderate, whereas soil transmitted helminthosis were intense.
