Prevalence and risk factors associated with human Intestinal Parasitic Infections (IPIs) in rural and urban areas of Quetta, Pakistan

Abstract Intestinal parasitic infections (IPIs) are endemic worldwide and more prevalent in countries with unhygienic conditions. The objective of the research was to identify the prevalence of intestinal parasitic infections in rural and urban areas of Quetta, Balochistan and to check their associated risk factors including; age, gender, educational status, sanitary system and any other immunodeficiency. For this instance 204 stool samples were collected from the urban and rural population of Quetta, Balochistan. The participants with positive results for Intestinal Parasitic Infections were interviewed using close-ended questionnaire. From the findings of this study, it has been revealed that prevalence of Intestinal parasitic infections in rural and urban areas was 21%. Males were found more prevalent (66%) as compared to females (34%) due to higher risk of contacting to outer environment. The prevalence was higher in rural areas (23%). The most prevalent intestinal parasite was Entamoeba histolytica (48%). Other prevailing parasites were Hymenolepis nana (26%), Giardia Intestinalis (17%), Trichomonas hominis (5%) and Trichuris trichiura (5%). The majority of patients were having lower socio-economic (52%) and educational status (48%). Educational status of 48% patients was primary or below primary. Most of the participants with positive results did not have hand washing habit (62%) and didn’t have the closed sanitary system (71%). The intestinal parasitic infections were more prevalent among children aged from 1-10 (33%). This may be a result of poor hygiene in children. The study will contribute to lower down the prevalence in the studied areas by the application of different preventive measures in future.
