Some articles on Internet say that if the wound on body is big and deep, and the bleeding is very serious, you will have chance to contract HIV when your wound is contacted by people's blood who is HIV +. Do you agree it? Is there anyone who gets HIV infection by blood contact through his or her wound on body in the world?
Thank you for your inquiry. From what we gather from the question, you were asking about the potential for HIV transmission from an individual's blood into an open actively bleeding wound. From the information given, this scenario is determined to be Low Risk: (Evidence of transmission occurs through these activities when certain conditions are met).
With that said, transmission through blood to blood contact is quite unlikely. For transmission to be possible, both people have to be actively bleeding with deep and severe wounds. Keep in mind, even when a wound is actively bleeding, the body is continually pushing the blood out, which may act as a preventative mechanism from anything getting in. The HIV virus is very fragile and dies within seconds once exposed to air; therefore HIV positive blood would need to immediately enter the other person's wound. If only one person were bleeding, the other person would have no direct access for the virus to enter their bloodstream. When your body becomes infected with HIV, it detects the virus and then begins to produce specific antibodies in response. The window period is the time it takes for your body to produce enough antibodies that they will be detectable in an HIV test, up to 95% of infections are detectable within 4 - 6 weeks. It should be noted that testing is the only way to be sure if transmission has occurred, and if this scenario has occurred please proceed with the necessary resources to get tested.
Recommendation: Refer to a health care provider for HIV testing
