HIV is unable to reproduce outside its living host (unlike many bacteria or fungi, which may do so under suitable conditions), except under laboratory conditions; therefore, it does not spread or maintain infectiousness outside its host.
"Blood to Blood Exposures". We get questions about this all the time. HIV is classified as a "blood borne pathogen", which is where a lot of this fear comes from. It basically means that the virus has to reach the bloodstream. In sexual exposures, it does this through the mucous membranes of the vagina or anus, which are VERY vascular, with very easy access to the vascular system. In a needle sharing scenario, a person is injecting infected blood DIRECTLY into their bloodstream. These situations are VERY different from a superficial skin "exposure":
Someone has a cut and was exposed to someone else's cut. This does not pose a risk for many reasons. First, the skin serves as an EXCELLENT barrier to the virus. The skin is comprised of several layers, and injuries, like paper cuts, etc...begin healing IMMEDIATELY from the inside out. Therefore, even if there IS a superficial abrasion/laceration, it will not allow the virus to penetrate deep enough to reach the bloodstream, which is what has to happen for infection. In a VERY severe scenario, there may be a risk....for example, two people being in a car accident with large major hemorrhaging injuries where there is HUGE exposure to the other person's blood through a very significant (deep) injury. However, again...being exposed to someone else's blood in small amounts, even with a small cut, will NOT place you at risk. "
thx for you reply but can you give more explation why the virus can not go to my blood throu this wound ?? actually i forgot to tell that the wound seems like fresh and almost bleeding .
No risk at all. your cut / wound doesn't permits virus to get into your blood streams / veins.
