The aim of this study is to determine the prevalence of intestinal and blood parasites among school children aged between 6 and 13 years.
Nine hundred and fifty eight stool samples (215 from rural areas & 743 from urban areas) and the same number of blood samples (215 from rural areas & 743 from urban areas) formed the subject of this study.
All stool samples were examined using both normal saline sedimentation method and formal ethyl-acetate sedimentation method.
From each blood sample, a thick and a thin blood film were prepared, stained with Giemsa stain and examined for malaria parasite.
Of 958 stool specimens 48% were positive in the rural area and 53% were positive in the urban area for at least one parasite.
In rural areas, Ascaris lumbricoides, (20%) Schistosoma mansoni, (15%) and Giardia lamblia, (9%) had the highest prevalence.
Hymenolepis nana and Enterobius vermicularis ova were found in 2% of specimens.
Taenia saginata ova and Entamoeba histolytica cysts were found in 3% and 4% of specimens.
In urban areas, Giardia lamblia and Hymenoplepis nana had the highest prevalence (11% & 5.5%). Ova of Ascaris lumbricoides were seen in 2% of specimens and Trichuris trichiura and Enterobius vermicularis were seen in 1% of specimens.
Entamoeba histolytica cysts were found in 3% of specimens.
The lowest prevalence (0.5%) was reported for both Taenia saginata and Schistosoma mansoni. (...)
