What is the incubation period range for Hepatitis A?

The incubation period is the time from when a person is exposed to Hepatitis A to when symptoms first appear. For Hepatitis A, that window ranges from about 15 to 50 days, with symptoms commonly showing up around the fourth week after exposure. This variability matters because it guides outbreak investigations: to identify possible exposure sources, you look back roughly two weeks to two months before illness onset. The other option ranges fall outside this typical HAV window—7 to 14 days is shorter and seen with other gut viruses, 60 to 90 days is longer and more in line with hepatitis B, and 10 to 20 days is not typical for HAV.
