<sec><title>Objectives</title><p><italic>Enterobius vermicularis</italic> is a parasitic disease that is common in crowded areas such as schools and kindergartens. Primary investigations of electronic evidence have reported different prevalences of <italic>E. vermicularis</italic> in Iran. Therefore, we aimed to estimate the total prevalence of this infection among Iranian children using a meta-analysis.</p></sec><sec><title>Methods</title><p>Relevant studies were identified in national and international databases. We selected eligible papers for meta-analysis after investigating titles, abstracts, and full texts; assessing study quality; and applying inclusion/exclusion criteria. Data were extracted by two independent researchers. The results were combined using a random effects model in Stata v. 11 software.</p></sec><sec><title>Results</title><p>Among 19 eligible articles including 11,676 participants, the prevalences of <italic>E. vermicularis</italic> among all children, boys, and girls were 1.2%–66.1%, 2.3%–65.5%, and 1.7%–65.5%, respectively. Pooled prevalences (95% confidence interval) of <italic>E. vermicularis</italic> among all children, boys, and girls were 17.2% (12.6%–21.8%), 17.2% (12.6%–21.8%), and 16.9% (9.03%–24.8%), respectively.</p></sec><sec><title>Conclusion</title><p>This meta-analysis showed that a great majority of Iranian children are infected with <italic>E. vermicularis</italic>, possibly due to poor public health.</p></sec>
