    Abstract:
    BACKGROUND: Hepatitis A virus (HAV) and Hepatitis E virus (HEV) are both enterically transmitted, resulting in acute viral hepatitis (AVH) in developing countries. They pose major health problems in our country. This study was done to determine prevalence of HAV and HEV in patients presenting with AVH and the co-infection of HAV and HEV in these patients. MATERIALS AND METHODS: A cross-sectional study of 2-years duration was conducted in the Department of Microbiology, KMC, Mangalore. A non-random sampling of 958 patients presenting with AVH was considered in the study. On the basis of history, serum samples were analysed for IgM anti-HAV and IgM anti-HEV for the detection of HAV and HEV, respectively using commercially available ELISA kits. Data collected was analysed by using Statistical Package for the Social Sciences (SPSS) version 11.5. RESULTS: The seroprevalence of HAV- and HEV-positive patients were 19.31% and 10.54%, respectively. The seroprevalence of both HAV and HEV in patients with acute viral hepatitis was 11.5%. The prevalence of HAV and HEV among males (68% and 31%) was higher than in females (31% and 20%) and was predominantly seen among young adults. These infections were predominantly seen during end of monsoons and beginning of winter. CONCLUSION: Though the prevalence of HAV is much higher than that of HEV, co-infection rate of 11.5% mandates the screening for HEV which will be of immense importance in pregnant women and improving levels of personal hygiene among higher socio-economic population. These data will be essential for planning of future vaccination strategies and for better sanitation programme in this part of the country.
