I am happy to say that there is no risk whatsoever of becoming infected with hiv, for the following reasons:
1. The blood did not enter your bloodstream - hiv does not pass through intact skin, or even healing wounds.
2. A wound must be fresh and deep, and the other person's infected blood to be of a high quantity, for there to be any kind of risk.
Hiv is a difficult virus to become infected with. If you avoid sharing needles, and make sure that you use a condom properly for vaginal/anal sex, this is a disease you need ever worry about.
You did not get hiv from this scenario. If you require further reassurance, please visit aidsmeds.Com, and post in the 'fears' forum. True experts will answer you within minutes.
No risk. No way, no how.
