Intestinal Parasitic Infections in Children from Northern Pakistan.
Infect Dis J Jan ;12(3):73-7.

Introduction: Intestinal parasitic infections cause significant morbidity in children of developing countries, where the vicious cycle of infections and malnutrition impairs their physical growth and development. Methods and Materials: A community based cross-sectional study on randomly selected children under 15 years of age was performed in two towns of Northern Pakistan. Information on hygiene, sanitation, waste disposal, water supply and maternal education was collected and the nutritional status of these children was assessed. Stool samples of the subjects were collected, immediately preserved and later examined for parasites, with severity of infection being quantified. Results: Of the 89 samples examined, 91% contained one or more parasites. The lowest prevalence of infection was in children less than one year old. Majority of those infected in both towns were girls. Fifty-one percent of the infected children from Yasin and 38% from Singal suffered from malnutrition. Maternal education, family income and drinking water treatment did not affect the prevalence of infection in either town. The most frequent parasites isolated were Ascaris lumbricoides (66.3%), Entamoeba histolytica (27%), Blastocystis hominis (27%), Giardia lamblia (24.7%), and Trichuris trichiura (15.7%). Discussion: The results of this study indicate that parasitic infections in northern Pakistan have a high prevalence but low intensity. Programs for early detection and interventional strategies, along with improved hygiene, sanitation and waste disposal facilities are urgently needed to improve the health of these children.
