"Identification des communautes cibles en zone de bilharziose urinaire par la methode de ""Lot Quality Assurance Sampling"" a Madagascar"

ABSTRACT

"Use of lot quality assurance sampling in the identification of Schistosoma haematobium endemic communities in Madagascar"" Reduction of morbidity is the main component in the National Schistosomiasis Control Program in Madagascar. The lot quality assurance sampling (LQAS) method has previously been shown as a useful tool in assessment of immunization coverage. A study was carried in the western part of Madagascar aiming to evaluate the applicability of the method in measuring the level of Schistosoma haematobium endemic level in different communities. Parasitological examination of urine samples from 1 124 children aged 5 to 19 years from 12 different schools by use of filtration technique constituted the reference in determining the prevalence. Three schools were found hyper-endemic (prevalence more than 60"
