Although 90 per cent of the people infected with hepatitis B are cleared of the infection, about ten per cent go into the chronic phase .Hence the outcome of the disease is different for different people. After the infection, in the first 6 months the person has acute hepatitis – hence this phase is known as the acute phase.
