Ecto and endoparasites in two primary schools in Qualyob City, Egypt.

Ecto and endoparasites are still one of the public health problems in Egypt. This is particularly true among school students who are exposed to the parasitic infections or infestations by autoinfection or by contagious. In this paper, two primary schools were selected in Qualyob City, Qualyobia Governorate (in the Nile Delta). Examination of 486 school children (6-12 years old) revealed pediculosis (16.04), schistosomiasis (8.8%), amoebiasis (7.81%), giardiasis (9.05%), taeniasis saginata (0.41%), ascariasis (9.05%), enterobiasis (0.9%) and hymenolepiasis nana (9.87%). It was found that ectoparasites (lice) represented 17.8% of the total parasites detected in the children. Endoparasites transmitted by autoinfection represented 43.02%, those transmitted by skin penetration represented 9.84%, those transmitted by meat consumption represented 0.45% and by other modes of infection represented 28.8%. It was concluded that school children are the group of individuals at risk. They spend long time outside their homes in a crowd area. Besides, they convey the parasites, particularly those transmitted by contagious and autoinfection to their family members.
