Overview
Hepatitis A virus (HAV) infection can be either asymptomatic or symptomatic.[1] Symptoms of hepatitis A include fever, fatigue, loss of appetite, nausea, vomiting, abdominal pain, and jaundice.
Symptoms
Young children who are infected with hepatitis A typically have a milder form of the disease, usually lasting from 1-3 weeks, whereas adults tend to experience a much more severe form of the disease. Some patients, particularly young children, are asymptomatic. When symptoms are present, they usually occur abruptly. Symptomatic adult patients may have a range of symptoms that can vary in severity from a mild flu-like illness to fulminant hepatitis.Symptoms of hepatitis A infection include the following:
- Fever
- Fatigue
- Loss of appetite
- Nausea
- Vomiting
- Abdominal pain
- Dark urine
- Clay-colored stool
- Joint pain
- Jaundice (children younger than 6 years of age typically do not show jaundice, while more that 70% of older patients do.)
- Pruritus
