What will happen if someone test positive to hepatitis b during visa screening to america.?

what will happen to someone who test positive to hepatitis b during visa sreening to usa,will he be denied entrance or accepted and treated?am asking for a worried friend of mine.

Okay, there are consequences as to how, or actually when, the onset of infections occured. The main question is, did your friend already submitted all the medical/health-related paperwork BEFORE getting hepatitis b or is your friend, having hepatitis b at the moment, GOING TO submit proof of health to immigration? Because depending on when your friend submitted the proof of health could mean possible entry or waiting.

What I mean in the first scenario is that if your friend already submitted the medical report to INS (I assume) prior to having hepatitis b, then technically your friend is "clean", so to speak, in paper, since there are no histories of any infectious disease whatsoever. This means that your friend, unless of course another medical report is needed, would not have any problems with the medical report papers and would not be completely hassled by INS because your friend is "clean" on paper; somehow, your friend can "get away" with this unless INS wants another medical report (possible, but unlikely if a recent medical report has been submitted), your friend is honest and tells about it to INS (not a good idea, if your friend wants to get the Visa), or someone leaks about it (hopefully not, so keep it a secret).

The second scenario is rather complicated, since the medical report would show that your friend has hepatitis currently (if the infection is current), which means that your friend either has to wait until your friend has been cleared of the infection or, worst case, your friend may get, at this point only, denied in getting the visa. Of course, the latter is only a speculation, but it is something to reconsider should this scenario be the case at hand.

This changes definitely if your friend has been cleared of the infection but tested positive for hepatitis b (this is possible, and does happens since free-floating hepatitis b antigens could be circulating in a previously-infected person even after there are no infectious hepatitis b viral particles). In such a case, your friend can consult an immigration lawyer to circumvent a dilemma that involves complications regarding this scenario.

If all else fails, consulting a lawyer is always the best option (which I would recommend), since what I have stated are possibilities for your friend's case.

Hope this helps!
