About Hep-A

Hepatitis A is a highly contagious liver infection caused by the hepatitis A virus. The virus is one of several types of hepatitis viruses that cause inflammation and affect your liver's ability to function. You're most likely to get hepatitis A from contaminated food or water or from close contact with a person or object that's infected. Mild cases of hepatitis A don't require treatment. Most people who are infected recover completely with no permanent liver damage.

Practicing good hygiene, including washing hands frequently, is one of the best ways to protect against hepatitis A. Vaccines are available for people most at risk.

Symptoms

Hepatitis A signs and symptoms typically don't appear until you've had the virus for a few weeks. But not everyone with hepatitis A develops them. If you do, hepatitis signs and symptoms can include:

  • Fatigue
  • Sudden nausea and vomiting
  • Abdominal pain or discomfort, especially on the upper right side beneath your lower ribs (by your liver)
  • Clay-colored bowel movements
  • Loss of appetite
  • Low-grade fever
  • Dark urine
  • Joint pain
  • Yellowing of the skin and the whites of your eyes (jaundice)
  • Intense itching

These symptoms may be relatively mild and go away in a few weeks. Sometimes, however, hepatitis A infection results in a severe illness that lasts several months.

When to see a doctor

Make an appointment with your doctor if you have signs or symptoms of hepatitis A.

Getting a hepatitis A vaccine or an injection of immunoglobulin (an antibody) within two weeks of exposure to hepatitis A may protect you from infection. Ask your doctor or your local health department about receiving the hepatitis A vaccine if:

  • You've traveled out of the country recently, particularly to Mexico or South or Central America, or to areas with poor sanitation
  • A restaurant where you recently ate reports a hepatitis A outbreak
  • Someone close to you, such as a roommate or caregiver, is diagnosed with hepatitis A
  • You recently had sexual contact with someone who has hepatitis A

Causes

Hepatitis A is caused by a virus that infects liver cells and causes inflammation. The inflammation can affect how your liver works and cause other signs and symptoms of hepatitis A.

The virus most commonly spreads when you eat or drink something contaminated with fecal matter, even just tiny amounts. It does not spread through sneezing or coughing.

Here are some of the specific ways the hepatitis A virus can spread:

  • Eating food handled by someone with the virus who doesn't thoroughly wash his or her hands after using the toilet
  • Drinking contaminated water
  • Eating raw shellfish from water polluted with sewage
  • Being in close contact with a person who's infected — even if that person has no signs or symptoms
  • Having sex with someone who has the virus

Risk factors

You're at increased risk of hepatitis A if you:

  • Travel or work in areas of the world where hepatitis A is common
  • Attend child care or work in a child care center
  • Live with another person who has hepatitis A
  • Are a man who has sexual contact with other men
  • Have any type of sexual contact with someone who has hepatitis A
  • Are HIV positive
  • Have a clotting-factor disorder, such as hemophilia
  • Use any type of illegal drugs (not just those that are injected)

Complications

Unlike other types of viral hepatitis, hepatitis A does not cause long-term liver damage, and it doesn't become chronic.

In rare cases, hepatitis A can cause a sudden loss of liver function, especially in older adults or people with chronic liver diseases. Acute liver failure requires a stay in the hospital for monitoring and treatment. Some people with acute liver failure may need a liver transplant.

Prevention

The hepatitis A vaccine can prevent infection with the virus. The vaccine is typically given in two shots. The first one is followed by a booster shot six months later.

The Centers for Disease Control and Prevention recommends a hepatitis A vaccine for the following people:

  • All children at age 1, or older children who didn't receive the childhood vaccine
  • Laboratory workers who may come in contact with hepatitis A
  • Men who have sex with men
  • People with other risk factors who work or travel in parts of the world where hepatitis A is common
  • People who use any type of illegal drugs, not just injected ones
  • People who receive treatment with clotting-factor concentrates
  • People with chronic liver disease

If you're concerned about your risk of hepatitis A, ask your doctor if you should be vaccinated.

Follow safety precautions when traveling

If you're traveling to parts of the world where hepatitis A outbreaks occur, take these steps to prevent infection:

  • Peel and wash all fresh fruits and vegetables yourself.
  • Don't eat raw or undercooked meat and fish.
  • Drink bottled water and use it when brushing your teeth.
  • Avoid all beverages of unknown purity, with or without ice.
  • If bottled water isn't available, boil tap water before drinking it.
