Hepatitis A is a contagious liver infection caused by the hepatitis A virus (HAV). Most cases are mild and clear up on their own. But the virus spreads easily through contaminated food and water, as well as close contact with someone who has it. You can protect yourself and others by getting vaccinated and practicing good hygiene.

Some people with hepatitis A have no symptoms, while others may feel unwell for several weeks or months. Most people recover completely without lasting liver damage. In rare cases, hepatitis A can cause liver failure, especially in people who already have liver problems.
There’s no specific treatment for hepatitis A, but most people get better on their own as their body clears the virus. Getting plenty of rest and drinking enough fluids can help you feel better while you recover.
Symptoms of hepatitis A typically appear two to six weeks after you get the infection. But not everyone has symptoms. Adults are more likely to develop them than children.
If you do have symptoms, they can include:
Your symptoms should go away within two months. For some people, they may last as long as six months.
The hepatitis A virus (HAV) causes hepatitis A. It spreads through contact with an infected person’s poop. Hepatitis A transmission occurs when even tiny amounts of infected poop enter your mouth. This is called fecal-oral transmission.

You may get infected with hepatitis A by:
You can also get it by having close contact with someone who has the infection. Hepatitis A can spread during sexual contact, especially oral-anal contact. But it doesn’t spread through sneezing, coughing or casual contact.
Yes. Hepatitis A is very contagious. The virus spreads easily from person to person. You’re most contagious two weeks before symptoms start. The risk goes down after symptoms appear. But you can still spread the virus even if you don’t have symptoms.
Anyone who hasn’t been vaccinated against hepatitis A or previously had the infection can get it. But you’re at a higher risk if you:
Hepatitis A doesn’t cause liver damage or disease like other hepatitis viruses. That’s because it’s usually a mild illness. Most people get better before the virus can cause complications.
Rarely, hepatitis A can lead to liver failure. This is more common in people over 65 and those with preexisting liver conditions.
A healthcare provider will ask about your symptoms and do a physical exam. During this exam, they’ll look for signs of liver disease, like:
You’ll need to get a blood test to diagnose the condition. This test will check your blood for HAV antibodies. Your immune system creates antibodies in response to viruses. If you have HAV antibodies, your provider can confirm you have hepatitis A.
There’s no cure for hepatitis A, and there’s no specific treatment. Most people recover completely within six months. The virus usually goes away on its own. Hepatitis A treatment focuses on managing your symptoms. Your healthcare provider may recommend:

Some medicines, like acetaminophen, may be safe to relieve symptoms in the right doses. Check with your provider before taking any medications or supplements.
Hepatitis A symptoms last for as long as it takes your immune system to defeat the virus. Most people recover within two months. If you have a weakened immune system, the infection might last longer, up to six months. Sometimes, symptoms appear to be gone but then come back (relapse).
If you think you may have a hepatitis A infection, contact a provider as soon as possible for testing. If you’re recovering from the infection, contact your provider if your symptoms get worse or aren’t improving. They’ll figure out the next step in your treatment.
Most people with hepatitis A recover completely. You may feel unwell for several weeks to months. But your body should eventually clear the virus without treatment.
Rarely, people develop chronic liver disease or other complications. It’s important to see a healthcare provider right away if you have symptoms of hepatitis A.
The best way to prevent hepatitis A is through immunization. Your provider can give you the hepatitis A vaccine in two doses. This can provide long-term protection from the virus.

If you’ve been exposed to hepatitis A, getting vaccinated within two weeks can help prevent infection.
Other ways you can prevent hepatitis A include:
Living with or recovering from hepatitis A can be stressful, especially when you’re waiting for symptoms to improve. Remember that most people heal fully with time and supportive care. If you have questions, new symptoms or concerns, reach out to your healthcare provider. They’re there to help guide you through treatment and recovery.
