Hepatitis A is a vaccine-preventable, contagious liver disease caused by a virus. Symptoms range from mild illness to a severe sickness that requires hospitalization and can last several months. Most adults with hepatitis A have a sudden onset of symptoms such as tiredness, low appetite, stomach pain, nausea, dark urine, and jaundice (yellowing of the skin and eyes). Most children younger than six years of age do not have symptoms or have an unrecognized infection. If you develop symptoms of hepatitis A, please contact your health care provider.

This disease usually spreads when a person ingests the virus from contaminated objects, food, or drinks. It can also spread from close contact with an infected person such as caring for someone who is ill.

Outside of these circumstances, the risk of infection is extremely low. Hepatitis A is not spread through casual contact, such as shaking hands or being in the same room as an infected individual.

The best way to prevent hepatitis A infection is to get vaccinated. Other preventive measures include practicing good hand hygiene - thoroughly washing hands after using the bathroom, changing diapers, and before preparing or eating food.
