About this study

Official title: Epidemiological Survey of Hepatitis D Virus Infection in Hepatitis B Population Among Multi-center Hepatitis B Population in China

This cross-sectional study will screen out hepatitis D virus-infected patients in HBsAg-positive people. Observe and describe the prevalence of hepatitis D infection among HBsAg positive people. The provinces of China are divided into 5 geographical areas (North, South, East, West and Central) to recruit patients according to the population density of each area. After statistical calculation, the total number of population needed is 3808.
