Brief Summary

Hepatitis B virus (HBV) infection is a major public health problem facing the world, with more than 2 billion people infected with HBV. There are more than 400 million chronic carriers, and 75% of carriers live in the Asia Pacific region. The mother-to-child transmission route of hepatitis B virus is recognized as one of the most important routes of transmission, and recent studies have found that fathers who are carriers of HBV may also be one of the risk factors for HBV infection in children, but as far as the investigators know. Therefore, as a high-population area in China, the purpose of this study is to investigate the prevalence of HBV infection in this population.
