  • Fatigue
  • Loss of appetite

Who should I contact if I believe I have been exposed to Hepatitis A?

Call your health care provider if you have any questions about potential exposure to Hepatitis A. If you don’t have a health care provider, contact your local health department.

What treatment options are available?

If you have been exposed to the Hepatitis A virus within the last 14 days and have not been vaccinated against it, you might benefit from either immune globulin or Hepatitis A vaccine.

How can I prevent the spread of Hepatitis A?

Frequent hand washing with soap and warm water after using the bathroom, changing a diaper or before preparing food can help prevent the spread of Hepatitis A.

What is the difference between Hepatitis A, B and C?

There are three different types of Hepatitis (A, B and C).Each type is caused by a different virus. Although they can cause similar symptoms, they have different modes of transmission and can affect the liver differently. There are vaccines to prevent Hepatitis A and B;however, there is not one for Hepatitis C. If a person has had one type of viral hepatitis in the past, they aren’t protected against other types.
