A cross-sectional survey was conducted to evaluate the burden of intestinal parasitic helminths and to determine the epidemiological aspects of the disease. The study area included Mansoura city as an urban area and Gogar village as a rural area. 1000 individuals were randomly selected from each area. Different methods of faecal examination, perianal swab and urine examination of all participants showed the incidence of the following organisms in Mansoura city: Heterophyes heterophyes, 6.4%; Enterobius vermicularis, 3.9%; Hymenolepis nana, 2.2%; Schistosoma mansoni, 0.5%; Trichostrongylus colubriformis, Strongyloides stercoralis and Fasciola sp., 0.2% of each; Taenia saginata, Ascaris lumbricoides and Trichocephalus trichiura, 0.1% of each. Neither Ancylostoma duodenale nor Hymenolepis diminuta was recorded. In Gogar, the incidence of parasitic infection were: H. heterophyes 4.5%; E. vermicularis 4.1%: H. nana 3.3%; S. mansoni 1.6%; T. colubriformis 0.9%; S. stercoralis 0.5%. Fasciola sp. 0.4%; T. saginata, A. lumbricoides, H. diminuta, A. duodenale and T. trichiura, 0.1% of each. No S. haematobium was detected in both areas. The infection rates of H. heterophyes, E. vermicularis, H. nana, S. mansoni, Fasciola sp., T. colubriformis and S. stercoralis were relatively high in rural than in urban area. This was not surprising since the socioeconomic, hygienic conditions and medical services were relatively high in the city than in the village. Early identification of parasitosis paved the way for feasible treatment and control measures.
