If you think you have been exposed to hepatitis A, consult your doctor immediately. Your doctor will decide what is best for you, based on your age and overall health.

However, the vaccine or immune globulin are only effective if given within the first 2 weeks after exposure.
Q. Is Hepatitis A infection fatal or life-threatening?
Hepatitis A infection usually does not cause liver disease. However, in some cases, it may lead to acute liver failure which can be life-threatening.
Q. Is hepatitis A curable?
No, there's currently no cure for hepatitis A, but it normally gets better on its own within a couple of months. However, it is better to consult a doctor if you think you are exposed to hepatitis A virus to rule out any other serious conditions that have similar symptoms.
Q. Is Hepatitis A infection contagious?

Q. What is Post Exposure Prophylaxis (PEP)?
Post Exposure Prophylaxis (PEP) refers to trying to prevent or treat a disease after an exposure.

However, the vaccine or immune globulin are only effective in preventing hepatitis A if given within the first 2 weeks after exposure.
Q. I had hepatitis A in the past, can I get it again?
No. Once you recover from hepatitis A, you develop antibodies that protect you from the virus for life. An antibody is a substance found in the blood which is produced by the body in response to a virus. Antibodies protect the body from disease by attaching to the virus and destroying it.
