Per CDC:
The hepatitis A virus is highly contagious. People who get hepatitis A may feel sick for a few weeks or several months but usually recover completely and do not have lasting liver damage. In rare cases, hepatitis A can cause liver failure and even death. This is more common in older people and in people with other serious health issues, such as chronic liver disease.
KEY POINTS
Hepatitis A is a disease of the liver caused by the hepatitis A virus (HAV).
HAV infection usually causes a mild, short-term illness.
HAV is contagious and spreads through close person-to-person contact and eating contaminated food or drink.
Vaccination is the best way to prevent infection.
Signs and symptoms
Not everyone with hepatitis A has symptoms. Adults are more likely to have symptoms than children. If symptoms develop, they usually appear 2–7 weeks after exposure. Symptoms usually last less than 2 months, although some people can feel sick for as long as 6 months.
Symptoms can include:
Dark urine or clay-colored stools
Diarrhea
Feeling tired
Fever
Joint pain
Loss of appetite
Nausea, stomach pain, throwing up
Yellow skin or eyes (jaundice)
