How long will a person who is infected by hepatitis B can live?
The greater a person's age at the time of infection, the greater the chance their body will clear the infection. More than 95% of people who become infected as adults or older children will stage a full recovery and develop protective immunity to the virus. However, only 5% of new-borns that acquire the infection from their mother at birth will clear the infection. Seventy percent of those infected between the age of one to six will clear the infection. When the infection is not cleared, one becomes a chronic carrier of the virus.
