What is hepatitis A?

Hepatitis A is a vaccine-preventable disease caused by an infection of the liver with the hepatitis A virus (HAV). HAV is usually transmitted person to person through the fecal-oral route or through consumption of contaminated food or water.

Most adults and older children with hepatitis A have symptoms that usually resolve within 2 months after infection; children aged less than 6 years usually do not have symptoms, or they have an unrecognized infection.

Signs and symptoms associated with hepatitis A can include:

  • Abdominal pain
  • Dark urine or clay-colored stools
  • Diarrhea
  • Fatigue
  • Fever
  • Jaundice
  • Joint pain
  • Loss of appetite
  • Nausea
  • Vomiting

Hepatitis A is a self-limited disease that does not result in chronic infection. Treatment for HAV infection might include rest, adequate nutrition, and fluids. Hospitalization might be required for more severe cases.

Fact

The best way to prevent hepatitis A is by being vaccinated.
