The Epstein-Barr virus (EBV) is responsible for a spectrum of human diseases and demonstrates a considerable prevalence among various populations. Advances in molecular epidemiological research have enhanced our comprehension of EBV-related pathologies. In this study, our objective was to examine the epidemiological profile and clinical features of EBV infection in Chongqing, China. We enrolled patients suspected of EBV-related diseases who were admitted to the First Affiliated Hospital of Chongqing Medical University between May 2013 and November 2022. Inclusion criteria were based on those who underwent EBV-specific immunofluorescence or plasma EBV-DNA testing. Among 13 584 inpatients, the overall seropositivity rates for EBNA-1-IgG, EBV-VCA-IgM, EBV-EA-IgG, EBV-EA-IgA, EBV-VCA-IgA, and EBV-DNA were 91.89%, 7.22%, 18.00%, 16.19%, 30.78%, and 18.00%, respectively. The seropositivity rate for EBNA-1-IgG steadily increased with age. The seropositivity rate for VCA-IgM, an indicator of acute EBV infection, was highest in patients aged 11-20 years at 26.41%, decreasing to 2%-6% in older patients. Additionally, among 205 outpatients, the EBV-DNA positivity rate was 14.15%. In 3670 individuals from health check-up centers, the seropositivity rates for EBV-EA-IgA and EBV-VCA-IgA were 11.96% and 28.09%, respectively, and the EBV-DNA positivity rate was 11.92%, all of which were lower than those in inpatients. Among the 762 EBV-DNA positive inpatients, adults aged 31-40 years were th...
