Onset of symptoms for Hepatitis A typically occurs within how many days after exposure?

• A. 2-14 days
• B. 15-50 days
• C. 60-90 days
• D. 100-120 days

Answer: (B)

The incubation period is the time from exposure to when symptoms appear. For hepatitis A, this process takes time for the virus to replicate in the liver and for the body's immune response to kick in. Symptoms typically show up about two weeks to two months after exposure, with most cases falling between 15 and 50 days. That window best matches the usual course of HAV infection, while shorter ranges (like 2–14 days) would be too quick for this virus to cause noticeable illness, and much longer ranges (60–90 or 100–120 days) are not typical for hepatitis A.
