Hepatitis A Transmission and the Incubation PeriodWhen someone becomes infected with the hepatitis A virus, he or she will not feel sick immediately. The period between hepatitis A transmission and the beginning of hepatitis A symptoms is called the hepatitis A incubation period. It may be as short as 15 days or as long as 45 days; the average is 30 days.
