Objective:To determine the prevalence of intestinal parasitic infections and soil-transmitted helminths(STHs) among primary schoolchildren in El dhayga,Central Sudan.Methods:In this cross-sectional study,three fresh faecal samples were collected from each child,which were examined by direct wet mount,brine flotation,formalin-ether and Kato-Katz techniques.The intensity of each STH infection was expressed as the mean of eggs per gram counts of the three samples.Results:In total,142(90.4%) of 157 children harboured at least one type of intestinal parasite.Ascaris lumbricoides,Hymenolepis nana,Entamoeba histolytica and Giardia lamblia were the most common parasites found,with prevalence rates of 32.5%,30.6%,33.1%and 19.7%,respectively.Out of these 157 children,29(18.5%) harboured more than two intestinal parasitic infections.No cases of Schistosoma mansoni or Enterobius vermicularis were identified. Conclusions:The study demonstrates significant burden of intestinal protozoa and STH infections in this part of Sudan and highlights the need for preventive and intervention measures.
