What is the incubation (onset) time for Hepatitis A?

• A. 7-14 days
• B. 14-28 days
• C. 60-120 days
• D. 21-50 days

Answer: (D)

Hepatitis A incubation refers to the time from exposure to when symptoms appear. It’s typically about 15 to 50 days after exposure, with many cases clustering around about 28 days. That means the window that covers roughly three weeks to seven weeks after exposure best matches what actually happens. The 7–14 days option is too short, the 14–28 days option captures only part of the range, and the 60–120 days option is too long. So the range around 21–50 days fits the observed incubation period best.
