Hepatitis B is an infectious disease, not a genetic disease, because hepatitis B does not cause genetic changes in sperm or eggs, so it is not inherited. Hepatitis B can be transmitted from mother to child, which is called the mother-to-child transmission route of hepatitis B. This is called the mother-to-child transmission of hepatitis B. In the past, when there was no interruption, it was possible to transmit the disease for several generations, but now there are means to do so, namely through the administration of the hepatitis B vaccine and hepatitis B immunoglobulin to newborns. Some pregnant women with hepatitis B who have particularly high viral load can also take antiviral drugs to control the amount of virus, which can reduce the probability of transmission of intrauterine infection. With these means, the chances of transmission of hepatitis B from mother to child are greatly reduced. At present, with the application of these means, it is almost impossible to transmit the infection to the child, so it is even less likely to be transmitted for several generations with the current medical conditions.
