Digestive Diseases and Hepatitis A

What Are the Symptoms of Hepatitis A?

Hepatitis A is inflammation of the liver caused by the hepatitis A virus.

When symptoms occur, they may include:

• Jaundice (condition causing yellow eyes and skin, dark urine)
• Abdominal pain
• Loss of appetite
• Nausea
• Fever
• Diarrhea
• Fatigue

Children often have hepatitis A with few symptoms.

A person can spread the hepatitis A virus about a week before his or her symptoms appear and during the first week of having symptoms. People with no symptoms can also spread the virus.


How Is Hepatitis A Transmitted?

The hepatitis A virus is found in the stool of people with hepatitis A. It is spread from person to person by putting something in your mouth that has been contaminated with the stool of an infected person.

Therefore, hepatitis A is most commonly transmitted in drinking water or food contaminated with the stool containing the virus.

Are There Any Long-Term Effects of Hepatitis A?

Hepatitis A causes acute (short-lived) infection. The liver heals itself over a few weeks to months. Usually the virus doesn't cause any long-term problems or complications. However, according to the CDC, 10% to 15% of people with hepatitis A will have prolonged or relapsing symptoms over a six- to nine-month period. Rarely, patients will develop acute liver failure, which can be fatal, or require a liver transplant.

What's the Treatment for Hepatitis A?
There are no treatments that will cure hepatitis A. Your health care provider may monitor your liver function tests to be sure your body is healing appropriately.

Is There a Hepatitis A Vaccine?

Yes. Vaccination against hepatitis A is recommended for people older than 1 year old who:

• Are traveling to areas of the world with increased hepatitis A infection.
• Are men who have sex with other men.
• Have a blood clotting problem.
• Are injecting and noninjecting drug users.
• Have chronic liver disease.

The vaccine is given in two divided doses.

Can Hepatitis A Be Prevented?

Vaccination is your best defense against hepatitis A. In addition, if you come in contact with someone with hepatitis A you can receive a specific medication called immune globulin within two weeks of contact.

Good hygiene is also important. Always wash your hands with soap and water after using the bathroom, before and after handling food, and after changing a diaper.
