A prospective epidemiological survey of intestinal parasitism was carried out in the Pediatrics and Children's Surgery departments of the El Idrissi Regional Hospital in Kénitra (Gharb) among 300 hospitalized children. The survey identified 11 intestinal parasites: Entamoeba coli, Entamoeba histolytica/dispar, Endolimax nana, Giardia intestinalis, Iodamoeba butchilii, Blastocystis hominis, Ascaris lumbricoides, Trichuris trichuira, Enterobius vermicularis, Taenia saginata and Hymenolepis nana. Of the 300 children, 157 had at least one intestinal parasite (52.7%), with 91 cases of polyparasitism (30.3%). Among the intestinal parasites identified, oxyurosis is the first dominant intestinal parasitosis. The survey revealed that the age group most exposed to intestinal parasites is between one and nine years of age. Deteriorating hygienic and environmental conditions have increased rates of intestinal parasites in children living in rural areas. Most of the parasites identified are the result of poor hygiene, which means that those who carry them are at risk.
