Abstract: China has a high prevalence of hepatitis B virus (HBV) infection. Liver cirrhosis (LC) and
hepatocellular carcinoma (HCC) caused by HBV infection accounted for 60% and 80% of all HC and HCC
patients, respectively. Patients with HCC in China accounted for 53.5% of the world. Half of patients with
HBV infection were transmitted through mother-to-child route. Blocking mother-to-child transmission of
HBV has important social and economic significance. This review summarized the relationship between
HBV DNA load, viral genotype, drug resistance, chronic hepatitis activity and mother-to-child transmission.
Referring to the precision medicine, we proposed the precision concept of blocking mother-to-child
transmission based on HBV intrauterine infection, in order to provide theoretical basis for further study of
blocking HBV mother-to-child transmission.
