Despite the recognized past and potential future epidemic burden in Nepal, data on the serological and molecular characteristics of, and co-infections with, Hepatitis A, B, and C viruses remain scarce. This study aimed to perform a detailed virological and serological characterization of a 2014 outbreak in Biratnagar, Nepal, to define the etiology and evaluate diagnostic patterns. METHODS: In this cross-sectional study, 211 patients with suspected acute viral hepatitis were enrolled from three hospitals in Biratnagar, Nepal, during the outbreak peak (April-May 2014). Serum samples were tested for HEV RNA (qRT-PCR), antigen, IgM, and IgG (ELISA), alongside HAV IgM, HBV core antibody, and HCV antibody. Concordance between HEV markers was assessed using Cohen's ?, associations with co-infections via Fisher's exact tests, and clinical correlates with Mann-Whitney U tests. RESULTS: HEV marker positivity among the 211 patients was as follows: HEV RNA was detected in 12 patients (5.7%), HEV antigen in 29 patients (13.7%), and HEV IgM in 36 patients (17.1%), indicating acute or recent infection. HEV IgG, reflecting past or recent exposure, was detected in 62 patients (29.4%). All successfully sequenced HEV RNA-positive isolates were identified as genotype 1a, consistent with the predominant HEV genotype reported in Nepal. In contrast, HAV, HBV, and HCV infections were infrequent, each accounting for less than 3% of cases, and no significant co-infections were observed. Concordance between HEV markers was variable, supporting the utility of a combined molecular and serological diagnostic approach to capture infections at different stages. CONCLUSION: This study provides a detailed characterization of HEV markers during the 2014 Biratnagar outbreak and confirms the circulation of HEV genotype 1a. HAV, HBV, and HCV infections were uncommon, with no significant co-infections observed. These findings offer valuable insights into HEV marker distribution and co-infection patterns, which can inform public health strategies, including enhanced surveillance, improved access to safe water, and consideration of targeted vaccination to mitigate future outbreaks in endemic settings.
