Hepatitis A is caused by the hepatitis A virus. Someone who is infected may pass hepatitis A to others by not washing his or her hands, especially after using the bathroom. The infection can also be spread by anal-oral sex. You might also get the virus from:
You have a higher risk for infection if
Symptoms usually appear 2 to 6 weeks after you are infected with the virus. Sometimes hepatitis A is so mild that there are no symptoms.
If you have symptoms, the illness usually begins with these flulike symptoms:
Smokers may lose their taste for cigarettes.
After several days you may also have these symptoms:
Your healthcare provider will ask about your medical history and symptoms. Your provider will look at your skin and eyes for signs of hepatitis. Your provider will check your belly to see if the liver is bigger than it should be or hurts when it is touched.
You will have blood tests. If blood tests show that your liver is not working normally, your provider will do tests to find out if a virus is causing the problems. Tests that find a virus will also determine the type of virus. (Several types of viruses can cause hepatitis.)
The usual treatment is rest. Your healthcare provider will recommend that you avoid alcohol for at least 6 months.
Usually it is not necessary to stay at the hospital. If you become too dehydrated from nausea and vomiting, you may need to go to the hospital to get intravenous (IV) fluids.
Because this is a virus, antibiotics are not helpful.
Recovery from hepatitis A usually takes 4 to 8 weeks. Tiredness is the most persistent symptom. The disease rarely has lasting effects, such as permanent liver damage.
Hepatitis A can be spread only by people with active infections. It is usually contagious for 2 to 3 weeks before symptoms appear and for 2 to 3 weeks afterward. During this time, others can pick up the virus by touching anything contaminated with bowel movements of the infected person.
You can get shots that prevent hepatitis A. Two shots are given 6 to 18 months apart. Healthcare providers usually recommend that you get the shots if:
If you are planning travel to an area where hepatitis A is common, you should have the first shot at least 1 month before you start your travels. Check with your healthcare provider about when you should have a second shot. Two shots of this vaccine can protect against hepatitis A for many years.
Hepatitis A vaccine is available as a combination vaccine with hepatitis B. Ask your healthcare provider if this is recommended for you.
If you have been exposed to hepatitis A, you may be treated with the hepatitis A vaccine or you may be given a shot of immune (gamma) globulin. It is best to get the shot right after you have been exposed to contaminated food or have had contact with an infected person. Immune globulin may not always prevent hepatitis A, but it may make it milder. The protection begins almost right away but it lasts for just 2 to 4 months. Whether you are given the vaccine or the immune globulin will depend on your age and your health.
If you have an active hepatitis A infection, be especially careful to always wash your hands thoroughly after using the restroom. This will help prevent spread of the disease to others.
If someone in your household has hepatitis, take the following precautions:
