Answer

The incubation period of hepatitis A virus (HAV) is 2-7 weeks (average, 28 days). Clinical symptoms then develop, often with a presentation similar to that of gastroenteritis or a viral respiratory infection. The most common signs and symptoms include fatigue, nausea, vomiting, fever, hepatomegaly, jaundice, dark urine, anorexia, and rash.

HAV infection usually occurs as a mild self-limited disease and confers lifelong immunity to the virus. Chronic HAV infection does not occur. [9]
