fortunately...there are many way overinflated views of HIV risks. The "blood to blood" scenario comes up all the time. A poster will ask if exposure to another person's blood, or genital secretions to a cut or abrasion will lead to infection. The answer it NO! This kind of situation will not lead to infection for a few reasons. ONE, the "exposure" is taking place "outside" of the body, where the virus quickly becomes inactive when it is exposed to the elements. Secondly, there needs to be exposure to a significant amount of infectious fluids on a vulnerable surface (bloodstream or vascular mucous membrane as in the vagina or anus) in order for infection to occur.
