The present study was conducted retrospectively to assess the frequency of acute viral hepatitis among the clinically suspected dengue cases presented at our tertiary care centre during 2021. To determine the presence of acute viral hepatitis; Hepatitis A virus (HAV) and Hepatitis E virus (HEV) infections, 104 specimens were selected from the dengue-suspected clinical specimens received during 2021 on the basis of acute viral hepatitis symptoms. Following this, serological diagnosis was performed on those samples using anti-HAV IgM and anti-HEV IgM ELISA kits. Based on sero-positivity for IgM antibodies, 3 (5.3%) dengue virus (DENV) seropositive samples were positive for both HAV and HEV, while among DENV seronegative cases, 11 (22.91%) samples were positive for HEV and 1 (2.08%) sample was positive for HAV, pointing towards misdiagnosis due to overlapping symptoms. Additionally, co-infection of HAV & HEV in 1 sample was also observed in this study. This study revealed the presence of acute hepatitis infections among the dengue cases during monsoon and post-monsoon season. Overlapping of the clinical manifestations of these diseases can create misdiagnosis incidences raising risk for underreporting of the true cases of acute viral hepatitis infection. Dengue-suspected patients with selected symptoms during the monsoon and post-monsoon season should additionally be screened for acute hepatitis infections, as suggested in this study.
