Seropositivity of hepatitis A and E viruses in patients attending a tertiary care center in central India

Objectives: Hepatitis A virus (HAV) and hepatitis E virus (HEV) infections are significant global health concerns that contribute to acute viral hepatitis. This study aimed to investigate the prevalence of HAV, HEV, and co-infections in a tertiary care hospital setting in central India. Materials and Methods: This retrospective observational study analyzed 987 clinical specimens collected from suspected acute viral hepatitis cases over 5 years (2019–2023). Commercially available enzyme-linked immunosorbent assay kits were used to detect HAV and HEV immunoglobulin M antibodies. Statistical analysis: Demographic data and clinical information were collected and analyzed using Chi-square tests. P < 0.05 was considered statistically significant, indicating a significant association between the variables under investigation. Results: Overall, 32.72% of patients were seropositive for either HAV, HEV, or both. The prevalence of HAV was 22.9%, HEV was 9.83%, and co-infection was 3.24%. HAV infection was more prevalent in children (0–14 years), whereas HEV was more prevalent in adults. Both HAV and HEV infections were associated with elevated liver function markers, with the highest levels observed in co-infected cases. The monsoon season had the highest number of cases. Conclusions: This study revealed a substantial burden of HAV, HEV, and co-infections in central India. The observed sex—and age-specific prevalence patterns warrant further investigation. Effective public health strategies addressing sanitation, hygiene practices, and HAV vaccination programs are crucial to reducing the disease burden.
