I was wondering if one could get HIV from basically touching a surface which have had viral DNA extract, serum, or blood on it; and then by touching their (bleeding) pimple or acne (or any other area of the skin that is damaged enough make blood leak through) area of the skin.

From what I've seen, the answer is no due to the fact that the virus is not able to live (or better say stay infective) for that long outside the human body.
Popular science: How long do microbes like bacteria and viruses live on surfaces in the home at normal room temperatures? If I am not getting it wrong, the first paragraph states this fact clearly:

The answer is probably not what you want to hear: Microbes can live on household surfaces for hundreds of years. The good news, however, is that most don't. Some well-known viruses, like HIV, live only a few seconds.

If the information is right, what I still don't understand is:
If so, why is it not possible for it to be infective since there will still be RNA present on the surface (even after the virus is dead or no virus left), getting in contact with skin, and eventually with the blood through the acne or the blood in the damaged area? Because the whole strain would still be there and would have gotten into the body. (Maybe even along with the ingredients in the dried fluids?)

  • @LanfLang - to me the OP shows a clear question and signs of reasonable research. Unless it's been edited to improve, I don't think your comment is very relevant, as the points in it are already pretty well addressed, and it's clearly asking for general understanding not medical advice for a specific situation. – Stilez Sep 15 at 23:07
