Bitting and hiv

Question: 

Hello! Id like to know if bitting is considered a way of transmission of hiv. Someone i hardly know bite my cheek. It hurt abit when he bit me, i had a bite mark for a little bit but disapeared an hour or so later. I didnt bleed or bruise or anything. For hiv to be transmitted does one have to bleed? Also do bites always break the skin, or if it didnt bleed it means he didnt break my skin. Also, whos more at risk the person who bites or the person who gets bitten. I was hoping you guys can help me solve my situation and ease my anxities. Because now im worried i must get tested for this situation!
Thank you :)

Hi there and thank you for reaching out to AIDS Vancouver with your questions! We're happy to help.

The situation you describe is No Risk for HIV transmission for either party involved. This is for a couple of different reasons.

First of all, there is no exchange of bodily fluids in this situation. The person biting you is not a risk since HIV cannot be transmitted through saliva. Additionally, HIV needs direct access to the bloodstream in order to establish an infection. This can be provided by either very severe wounds (such as ones that require immediate medical attention such as stitches) or through mucous membranes in the anus, vagina, or urethra. Your cheek is just skin, and therefore is not a risk for HIV entry. Biting doesn't generally break the skin, and even if it did (which it did not in your case) there would still be no risk because of the fact that saliva doesn't transmit HIV, and that the wound wouldn't be severe enough to provide direct access to the bloodstream.

It may be helpful for you to consult this transmission equation. please note that you need all three components for there to even be a risk of HIV transmission at all.

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

= RISK OF HIV TRANSMISSION
