1) Yes, "not appreciable" and "not realistic" mean the same thing.
2) From my original reply: "...HIV can in theory be acquired by exposure to blood during fights, [but] to my knowledge this has never actually happened" and "Any blood exposure is theoreticallly a risk". Under the specific circumstance you describe ("if wound occurs the instant it is in contact with infected blood"), the risk would be higher. But since this must have occurred many times over the 30 years of the worldwide AIDS epidemic, and yet there are no known cases of HIV transmission during fights, even in these special circumstances the risk obviously is very low.
In other words, my opinion and advice are unchanged.
Hi, just wanted to come back for clarification and for future reference.
1. When you say 'no appreciable risk' do you mean not a realistic risk?
2. If the guy had fresh blood on his finger tips when he opened my healing scab (wound) would could entry to the bloodstream have been possible? I've heard before that if wound occurs the instant it is in contact with infected blood there could be a risk. Probably because it hasn't had time to clot. Is that true?
I'd be grateful if you could answer these 2 last questions.
I won't ask any more.
Thank you.
Thanks for the thanks. Merry Christmas to you as well.
Thanks Doc. I'm happy with you advice and won't bother testing. Feel crazy asking about this but just got stressed when thinking about it too much. Have a great Christmas ad new year!
Welcome to the forum. Thanks for your question. The quick answer is that there is no appreciable risk of HIV and I don't recommend testing. Here is my reasoning:
First and most important, although it is commonly stated that HIV can in theory be acquired by exposure to blood during fights, to my knowledge this has never actually happened. Any blood exposure is theoreticallly a risk, but this sounds pretty trivial. As you suggest yourself, a wound generally must be deep and fresh (actively bleeding) to risk HIV from exposure to infected blood. Exposure of skin rashes like eczema also is often listed as a risk, but here too there are few if any actual reported cases of such transmission. And of course even this assumes your fighting buddy has HIV, which probably isn't the case.
I think those comments cover all four of your specific questions, but let me know if there is anything you don't understand. I don't recommend HIV testing -- but of course you are free to do that, if these words are not sufficiently reassuring and you would feel better knowing you have had a negative test result.
