A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This cross-sectional study enrolls patients with chronic hepatitis B from several hospitals in Vietnam to measure HDV prevalence and genotype distribution. Researchers collect questionnaire data on epidemiologic risk factors and obtain a blood sample for testing. The study aims to identify factors related to HDV infection, including vaccination history, drug use, family and environmental factors, and lifestyle. Only individuals who consent and meet the HBV criteria are eligible to participate, and data collection occurs at multiple hospital sites. No experimental interventions are planned; the study is purely observational.
