| Popis: | Background: Hepatitis A virus (HAV) is a major cause of acute viral hepatitis worldwide. Annual medical and work loss costs of hepatitis A are significant even in low-endemic countries. It is recommended that each country should collect and review the information needed to estimate its national burden of hepatitis A to provide evidence for health policy makers to implement appropriate and cost-effective preventive strategy for HAV infection. The objective of this study was to estimate accurate prevalence of HAV infection in Iran for best preventive measures. Materials and Methods: MEDLINE, Institute of Scientific Information, Scopus, Iranmedex, Irandoc, Magiran and Scientific Information Database were searched. The seroprevalence of HAV were pooled by age, sex and residence using fixed and random effect models. Results: Sixteen papers representing 11857 subjects were included. The overall HAV seroprevalence was 51% (confidence interval [CI] 95%: 50-52%) in fixed and 66% (95% CI: 50-79%) in random effects models. The prevalence was 32% (CI 95%: 11-63%) in less than 20, 50% (CI 95%: 24-75%) in 20-30, and 67% (CI 95%: 17-95%) in more than 30 years of age. The difference was not significant in gender or residence subgroups. Conclusion: HAV infection in Iran may be considered as low or very low. Therefore, targeted vaccination of high-risk groups and more improvement in environmental sanitation would be the best preventive measure. |
