What are the symptoms of hepatitis A?
Not everyone who is infected with hepatitis A will display all symptoms of the disease. Adults have signs and symptoms of illness more often than children and the severity of disease and mortality increases in older age groups. 1
Symptoms of hepatitis A can include: 1
- Loss of appetite
- Abdominal discomfort
- Dark-coloured urine and jaundice (a yellowing of the skin and whites of the eyes)
Infected children under 6 years of age do not usually experience noticeable symptoms, and only 10% develop jaundice. Among older children and adults, infection usually causes more severe symptoms, with jaundice occurring in more than 70% of cases. 1
Ultimately, hepatitis A resolves completely in >99% of the cases, although relapse of symptoms has been reported in 3–20% of clinical cases. 2
