Introduction: Intestinal parasitic infection (IPI) remains major public health problem in worldwide, being most prevalent in developing countries. Mass drug administration with Mebendazole is an effective strategy for the control of these diseases in pre-school and schoolchildren. The aim of this study was to assess the prevalence of intestinal parasitic infections and established associated risk factors among pre-school and schoolchildren living in rural area in Senegal.

Materials and method: A cross sectional survey was carried out between Novembers to December 2014. Children less than 10 years were randomly selected using a systematic random sampling method. Stool samples were examined by light microscopy for the detection of parasite using direct examination, Modified Ritchie Method and the modified Ziehl Neelsen staining method.

Results: Among 392 children selected in the study, 137 were found with at least one intestinal parasite representing an overall prevalence of 34.95% [CI 95% (29.3–41.3)]. Protozoan infection was more frequent than helminthic infection (93.4% versus 2.2% respectively). Association between helminths and protozoa was 4.4%. Intestinal parasites identified were Giardia intestinales (72.48%), Entamoeba coli (13.76%), Blastocystis hominis (3.67%) and Hymenolepis nana (1.83%). Prevalence was higher among children aged over 5 years old (48.4%) (aOR= 5.39; 95% IC (2.06–13.9); p=0.001). Children living in family with more than 10 individuals and those drinking unsafe water were found most infected respectively 37.5%) (aOR= 1.24; 95% CI (0.65–2.38); p=0.51) and (42.3%) (aOR=1.45; 95% CI (0.83–2.52); p=0.18). Prevalence was higher in children with underweight 36.3% [aOR= 1.53; 95% IC (0.88–2.67); p=0.13). No correlation was found between sex and intestinal parasitic infection.

Conclusion: This study showed that intestinal parasites remain prevalent in pre-school and schoolchildren with a changing of the epidemiological profile. Protozoan infection was more frequent than helminthic infection. Preventive measures including mass drug administration with Albendazole and water supply could reduce the prevalence of these diseases.
