In those who develop symptomatic hepatitis A, flu-like symptoms, such as fever, chills, headache, and a general feeling of weakness, may occur. Other symptoms may also include anorexia (loss of appetite), nausea, jaundice (yellowing of the eyes and skin), dark urine, light-colored stools, abdominal pain, and fatigue.

Although hepatitis A does not result in chronic infection, complete recovery from hepatitis A can be slow. In children, especially in those younger than 6 years of age, there are often no obvious symptoms. Adult patients with hepatitis A may be quite ill for up to 2 months and full recovery can take up to 6 months. In addition, up to 22% of reported adult cases may require hospitalization.
