Hepatitis A Incubation Period
The hepatitis A incubation period can range from 15 to 45 days, and is dependent on the number of virus particles consumed. Fewer particles typically lead to a longer incubation time. During the hepatitis A incubation period, an infected person is contagious and remains so for about a week after jaundice appears (yellowing of the skin and whites of the eyes).

After four weeks (on average), symptoms of hepatitis A can appear. This period between transmission of the virus and the start of symptoms is called the "hepatitis A incubation period." This can be as short as 15 days or as long as 45 days. The incubation period is dependent on the number of virus particles consumed. Typically, infection with very few particles results in a longer incubation period.
