我国是乙型肝炎病毒(HBV)感染的高发流行区。人群中HBsAg阳性率约占10%,慢性HBV感染者约 1.3亿,特别是携带乙型肝炎病毒的孕妇,约有30- 50%是通过母婴传播形成的。当孕妇HBeAg阳性时,其新生儿80-90%将感染HBV并且成为慢性携带者,母婴传播是我国HBV最主要的传播途径,也是人群中大量HBV慢性携带者形成的重要原因,不仅造成我国HBV流行的主要因素,也可成为社会上的传染源,而且可发展为慢性肝炎、肝硬化、肝癌。因
Our country is a high endemic area of hepatitis B virus (HBV) infection. The population of HBsAg positive rate of about 10%, chronic HBV infection of about 130 million, especially pregnant women carrying hepatitis B virus, about 30 to 50% of the mother-to-child transmission formed. When pregnant women HBeAg-positive, 80-90% of their newborns will be infected with HBV and become a chronic carrier, mother-to-child transmission is the main route of transmission of HBV in our country is also an important cause of the formation of large numbers of chronic carriers of HBV in the population, not only caused China The main factor of HBV epidemic, but also can become a source of infection in society, but also for the development of chronic hepatitis, cirrhosis, liver cancer. because
