Hepatitis B?

My husband is positive "Hepatitis B core antibody" and all the other hepatitis B tests are negative, two months ago also he was having the same result.
Six months ago he was all negative.
I also tested my self it came all negative.
He is not having any health complications and he didn't have any troubles for the last three years.
Doctor told him you don't have to take any treatment; have sex with your wife without protection!!!!
My questions are:
1- Is the viruses still a live in his liver?
2-what is the chance to transfer the virus to me.
3- What is the likelihood for the virus to start active again?
4- Do you suggest any medicine for him at this stage?
5- Is the "Hepatitis B core antibody" test required for immigration or they are asking for the "Hepatitis surface antigen" test only

If it's cleared out of his system then it's cleared already. He's fine now, with an addition of an antigen in his liver, but that's no cause for alarm.

About your questions, I'll try my best to answer them
1. Nope; virus has cleared already...what the positive result means is that the core antigen (the actual molecular structure bound to the virus itself that reacts with the immune system's antibodies) is just in the surface of his liver; it could come off or just stay there depending on time, but just the core antigen will not do anything to your husband's body--think of it as craters on a moon after being bombarded with asteroids; or like scars after getting a wound. But no, there are no viruses capable of infection.
2. IF and ONLY IF your husband is STILL infected with Hep B virus, some of the possible ways he can transmit it to you is by blood transfusion, open wound to open wound contact, sexual intercourse, and sharing of needles, among others. Since your husband is clear already of the virus, you can pretty much do the ones I mentioned without having to worry about contracting the virus itself (unless of course he has another infection), although I don't have any logical response as to why you would do those.
3.No chace of it being active again, since it is only an antigenic determinant; if what was left was the viral DNA of Hep B virus and it somehow gets inside one of your husband's cells, then the whole thing might start all over again...this is in theory only; in reality, your husband would not have to worry so much about re-infection unless he gets re-infected.
4.Just like what the doctor ordered--none; if you want supplements such as Liverade, then that would be fine...just make sure that Liverade is ok for him to take.
5. Ah, now comes the tricky part, because this is a topic upon which immigration can get really picky and will scrutinize the hell out of people applying (if you guys are applying)...I am not being a tolerating person, but if the immigration asks for any infectious disease, but does not ask for any further medical record, just answer NO; I believe that this is not part of the criteria in reporting any infection that might have occured or currently occuring.

Hope this helps! And he's fine by the way. :)

does he truely ave hbv? sometimes the tests come back false positives. usually the virus can lie dormant in the liver till something activates it. try to get the hbv vaccine. it is a series of three shots. works well at preventing hbv.
