Seroprevalence of hepatitis B and hepatitis C virus infections in Diyala province during 2003-2008

Abstract

Background: The seroprevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are largely depend on the rate of chronic carrier in the community and the predominant route of infection.Objectives: to investigate the seroprevalence of hepatitis B and hepatitis C virus infection in Diyala province during the period from 2003 to 2008.Materials and methods: This study was conducted for the period from 1/February/2003 to 30/April/2008. Data were extracted from records of the virology unit in the Public Health Laboratory in Baquba. Data were translated to computerized data base and statistically analyzed.Results: The highest annual prevalence rate of HBV infection was found in 2004 (5.5/1000 tested samples) and highest annual prevalence rate of HCV infection was found in 2004 (2.5/1000 tested samples). The HBV and HCV positive cases were peaked in April months. The HBV positive cases were significantly higher among the age group (20-29) years (p <0.001). The HCV positive cases were significantly higher among the age group (30-39) years (p < 0.001). There is no association between HBV and HCV positivity rates and the district of residence. The HBV and HCV positivity rates were significantly higher (p= 0.009) in males compared to females.Conclusion: Although the annual seroprevalence of HBV is slightly decline, the annual seroprevalence of HCV is increased. Strengthening of surveillance system is recommended.
