Prevalence of intestinal parasites at Saint-Camille medical center in Ouagadougou (Burkina Faso), 1991 to 2010


, : Prevalence of intestinal parasites at Saint-Camille medical center in Ouagadougou (Burkina Faso), 1991 to 2010. Medecine et Sante Tropicales 22(1): 40-44

Intestinal parasitoses continue to be a major public health problem in developing countries. This study sought to evaluate the prevalence of intestinal parasites and their coinfection rates in patients attending the Saint-Camille medical center in Ouagadougou. Methodology. This retrospective study covers the period from 1991 through 2010. In all, 292,148 stool samples were analyzed, and 177,672 contained at least one parasite, for a prevalence rate of 60.82%. Protozoans accounted for 90.53% of the parasites identified (160,838) and helminthes 9.47% (16,834). The most common protozoans were Entamœba histolytica/dispar (39.88%), Trichomonas intestinalis (25.78%) and Giardia intestinalis (24.83%). The helminthes encountered most frequently were Hymenolepis nana (3.99%) and Ancylostoma spp (3.65%). Globally, the prevalence of parasites decreased over the 20-year study period. The prevalence of E. histolytica/dispar decreased while that of Giardia intestinalis became more frequent. The most common parasitic associations were E. histolytica/dispar-G. intestinalis (26.24%) and G. intestinalis-T. intestinalis (20.09%). Our results indicate that Burkina Faso is a zone at high prevalence of intestinal parasitosis, even though this prevalence appears to be decreasing. Appropriate strategies should be developed to accelerate the reduction in the incidence of these parasites.
