Continuing signs and symptoms of hepatitis A
A small number of people with hepatitis A will continue to experience signs and symptoms of infection for several weeks longer than usual. For these people, hepatitis A signs and symptoms may go away and then reappear over several weeks. Though the signs and symptoms occur over a longer period of time, this form of hepatitis A infection is not more serious than a hepatitis A infection that causes the usual signs and symptoms.
Acute liver failure
In rare cases, hepatitis A can cause acute liver failure, which is a loss of liver function that occurs suddenly. People with the highest risk of this complication include those with chronic liver diseases and older adults. Acute liver failure requires hospitalization for monitoring and treatment. In some cases, people with acute liver failure may require a liver transplant.
