While I was at lunch someone who sit's at my table poked another person with something like a tack but I don't think it was as sharp and then poked me with it as well. I then looked at the other kid who had been poked with it and I seen that he had a little bit of blood on his hand from it. I was not bleeding but it left 2 small redish pinkish marks that are still here 3 hours later. Could it have gotten in my bloodstream even though I wasn't bleeding or is a break in the skin enough to transmit HIV? Also what is the probability that the other kid was infected with HIV.

Hello and thanks for reaching out to the AIDS Vancouver Helpline.

It seems like you are concerned of contracting HIV through a bruise on your hand. We are glad to provide some information.

Superficial cuts and bruises do not pose a risk to HIV transmission. The virus needs direct access to you blood stream in order to transmit. If it is a cut it must be a deep cut that it requires stitches in order to transmit.

HIV TRANSMISSION EQUATION


BODY FLUID
+
ACTIVITY
+
DIRECT ACCESS TO BLOODSTREAM
---------- -------- ----------------------------
• blood (including menstrual) • unprotected anal or vaginal intercourse • vagina
• semen • sharing needles • anus
• pre-cum • mother to child (in specific cases) • urethra in the penis
• rectal secretions • open cuts and sores (in theory)
• vaginal fluids • other mucosal membranes
• breast milk • points of needle injection
The second thing is that when the virus is exposed to air it no longer transmit. So coming into contact with blood that has been exposed to air does not put you at risk. The activity you described does not put you at risk.

Additional information can be obtained from the [CATIE website](http://www.cdnaids.ca/home.nsf/ad7c054e653c96438525721a0050fd60/4d4cf16b70a7247f0525732500678839/$FILE/HIV_Transmission_Factors_that_Affect_Biological_Risk.pdf)
