Introduction: ‘Viral Hepatitis’ denotes a primary infection of liver by heterogeneous group of Hepatitis virus. They are clinically indistinguishable, leading to morbidity and mortality. Mainly diagnosed by serological and molecular markers. Hepatitis A and Hepatitis E viruses are transmitted by faeco-oral route and cause sporadic as well as outbreaks of acute viral hepatitis. Objectives: Prevalence of HAV and HEV in patients of acute viral hepatitis along with their co-existence and correlate it with seasonal trend. Materials & Methods: Study was conducted in our institute from January to December, 2018. 275 samples were tested for HAV and HEV infection of clinically suspected cases. Samples were analyzed for anti HEV IgM and anti HAV IgM antibody by ELISA method. Results: Out of 275 samples, 66 were positive for anti HAV IgM indicating prevalence rate of 24%, majority patients were in pediatric age group of 0-14 yrs. In case of HEV, 71 samples were positive with prevalence rate of 25.8%, majority patients were in age group 15-45 yrs. Infection rate was higher in males. Co infection rate was 1.09%. Seasonal trend shows maximum positive cases in summer and monsoon. Conclusion: HAV and HEV infection should be considered as an etiology of acute infectious viral hepatitis. It is suggested that health care facilities should make an effort to increase the awareness among general public for personal hygiene and cleanliness, thus reduce morbidity, mortality and economic burden.
