Background: Intestinal parasitic infection is highly prevalent among general population, majority of them are children. Aim: The objective of the study is to estimate the prevalence of intestinal parasites among children residing in Al Hasa. Methods: Retrospective study conducted from MCH laboratory data base from 2012 to 2013. Results: A total of 200 stool samples were reviewed and parasites were identified in (46.5 %) samples. The prevalence rate of IPI in male and female were 27% and 19.5%, respectively. Altogether four species of parasites were detected. Giardia lamblia was most common followed by Entamoeba coli, Entamoeba histolytica, and Enterobius vermicularis. Conclusions: Intestinal parasitic infections are highly prevalent and are of major public health concerns. IPIs are intimately associated with poverty, poor environmental sanitation and lack of clean water supply. Awareness on infectious diseases, improving hygiene, and application of supportive programs for parents to elevate their socioeconomic conditions may reduce the burden of infection.
