There is no specific such description of congenital hepatitis B in the information about hepatitis B. Congenital generally means that the disease was acquired before birth, and in the case of hepatitis B, this is a pregnant woman with hepatitis B who transmits the hepatitis B virus to her fetus through the placenta. In this case, the person’s life expectancy is not significantly affected if it can be treated well. However, if the child has acute severe hepatitis, or even infantile hepatitis syndrome, as a result of massive replication of the hepatitis B virus just after birth, there is a risk of premature death in this case. If the child does not have a particularly pronounced immune clearance of the hepatitis B virus and does not cause significant liver cell damage, it can be maintained in a state of hepatitis B virus carriage that is likely to be maintained into the teenage years or even into the tens of years. If there is liver cell damage in adulthood, after liver preservation and enzyme reduction treatment, as well as antiviral treatment, the hepatitis B virus can also prevent it from causing further cirrhosis and liver damage, and timely treatment, life expectancy is the same as normal people.
