Wound inside mouth and sharing food, HIV infection risk?

Question: 

Last evening, i accidentally bit the inside of my cheek while eating at dinner. The wound was big and much blodd came out; i washed with water, but i continued to feel the taste of my blood inside my mouth for about 1 hour. Then, 2 hours after this accident, i was at a party, an unknown girl offered me to try some of her ice cream that she was eating. She passed me her ice-cream scoop and i ate a small quantity of her ice-cream using her ice-cream scoop.
Now i am a bit concerned because it is very likely that my wound was still bleeding when i shared ice cream and ice cream scoop with that unknown girl, and i would like to know from experts if this event was at risk for any infectious disease.

Thank you very much!

Answer: 

Hello,

Thank you for your inquiry. From what we gather from the question, you were asking about the risk of acquiring HIV through a mouth wound by sharing food with someone. From the information given, this scenario is determined to be No Risk (transmission of HIV is not possible in the given scenario). However, there have been case reports of HIV being transmitted to babies when food was pre-chewed by the HIV positive mother/caregiver. [3, 4]

The scenario mentioned above does not meet the three components of the transmission equation. It does not satisfy the equation because HIV is not transmitted through the saliva and sharing food is not an activity that allows for HIV transmission. Refer to the sources below for more information on HIV transmission and the three components of the transmission equation.

Recommendation: No need for HIV test with the scenario provided, refer to a physician for other health-related questions.
