You can get hepatitis A from…

Hepatitis A comes from small amounts of infected fecal matter that is ingested, usually from contaminated food or drink. Foods can become contaminated with hepatitis A anytime from the growing, harvesting, processing, handling, or after cooking.

It can also be contracted by touching something that has the virus on it, and then touching food or putting your hands in your mouth. Hepatitis A may also be spread by close personal contact with an infected person through sex, caring for an infected patient, or changing a baby's diaper.

Hepatitis A contamination is more common in areas where sanitation is minimal and people have poor personal hygiene. In the U.S., Food and Drug Administration (FDA) monitors bodies of water for fecal contamination, and chlorine is used to kill any hepatitis A virus that enters the water supply.

Is hepatitis A contagious?

Hepatitis A is a highly contagious viral infection that typically spreads when a person unknowingly ingests the virus from food, drinks, or objects contaminated by undetected amounts of feces from an infected person.

Hepatitis A is most contagious shortly after infection, before symptoms appear. Healthy adults are no longer contagious 2 weeks after the illness begins. Children and people with compromised immune systems may be contagious for as long as 6 months.

Yes No

What are early symptoms of hepatitis A?

Hepatitis A usually does not cause symptoms in children under age 6. Older children may experience cold symptoms such as cough and sore throat. In adults, hepatitis A causes flu-like symptoms that start about a month after infection. Early symptoms of hepatitis A may include:
  • Extreme fatigue
  • Nausea
  • Vomiting
  • Loss of appetite
  • Feeling unwell (malaise)
  • Fever over 100.4°F (38°C)
  • Abdominal pain under the ribs on the right side

  • Dark urine
  • Clay-colored stool
  • Yellowing skin and eyes (jaundice)
  • Itchy skin
Nausea Vomiting Loss of appetite All of the above

Can hepatitis A go away on its own?

If you get the hepatitis A virus the body will clear the infection on its own, but it may take several months to feel better.

To help with recovery, get adequate rest, drink plenty of fluids, eat a healthy diet, and avoid alcohol and acetaminophen (Tylenol) which can harm the liver.

In more severe cases, hospitalization may be required.

There is a vaccination against hepatitis A.

There is a hepatitis A vaccine available and it is highly effective in preventing hepatitis A infection. The Advisory Committee on Immunization Practices (ACIP) recommends hepatitis A vaccination for the following people:

  • All children at 1 year of age
  • Travelers to countries where hepatitis A is common
  • Family and caregivers of people from countries where hepatitis A is common
  • Men who have sex with other men
  • Recreational drug users, whether injected or not
  • Homeless people or those with unstable housing
  • Patients with chronic or long-term liver disease, including hepatitis B or hepatitis C
  • People with clotting-factor disorders
  • People in direct contact with others who have hepatitis A
  • Anyone who wants to obtain immunity from hepatitis A

True False

How is hepatitis A treated?

It can take several months to recover from hepatitis A virus infection. If you have been recently exposed (within 2 weeks) to hepatitis A and are unvaccinated, it is recommended you receive the hepatitis A vaccine and/or a shot of immune globulin to prevent serious illness.

Once symptoms occur, home treatment is recommended. Get adequate rest, drink plenty of fluids, eat a healthy diet, and avoid alcohol and acetaminophen (Tylenol) which can harm the liver.

In serious cases hospitalization may be needed.

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

All forms of hepatitis affect the liver and cause similar symptoms. However, they are transmitted differently and affect the liver differently.

Hepatitis A infection usually only lasts a few months and does not become chronic, while both hepatitis B and C can result in chronic disease and liver problems.

There is no vaccine for hepatitis C, but there are vaccines to prevent hepatitis A and hepatitis B.

They cause different symptoms Hepatitis A does not become chronic Only hepatitis A affects the liver There is a vaccine for hepatitis C, but not A
