If you had exposure to Hepatitis A in the past, is it possible to contract the disease again in the future? I was talking to a nurse, and he mentioned that he had hepatitis A twice. I was under the assumption that you can only contract hepatitis A once.
Hello and welcome to the forum!
A person who has hepatitis A infection becomes immune to HAV for the rest of his life once he recovers. He cannot get hepatitis A twice. The blood test for immunity to hepatitis A is called the hepatitis A total antibody test. IgG antibodies are present in a person who has suffered from hepatitis A. You need to clarify your doubts with the nurse. Do write to us again with more queries. Hope it helps.
You can have any disease more that once, depending on what other problems you have with your immune system. I have some problems with my immune system and I have had hepatitis A twice and chicken pox a total of 5 times. In all the hepA and zoster cases, I was extremely ill and there was no doubt I had the diagnosed disease. I know it sounds bizarre, but I do have a PhD in biochemistry and molecular genetics focused on virology, so believe me it is possible. However, it is not typical for someone to contract these viral diseases more than once.
