A drunk lady wiped her profusely bleeding palm or hands on my forearm

Question: 

So I was walking last night along the sidewalk when a random drunk lady whose hand was bleeding profusely ( she hid her hand in her jacket) suddenly touched my forearm with her bleeding hand. I got so much blood on my forearm which i then washed to a nearby restaurant's washroom, it took me couple of mins to get to the washroom so it kind of dried on my forearms. And While i was about to go in the restaurant to wash she ran away with her friend and wont answer my question if she has any disease like hiv or any bloodborne disease. I have a small wound on the side of my posterior palm that i covered with bandage. Some blood stained the side of the bandage but not on top of the wound. I have no other wound on my forearm except very few redspot (like one or two petechiae) Probably it was around 15 ml of blood that stained my right forearm that i washed. I tried not to get my wound wet so as not to get any blood on it. Im not sure if a little water went to my wound while washing. It is small wound from burn that hasnt healed yet. Im just a bit worried. also im not sure if small bits of blood went anywhere else in my skin/ Should i get checked asap? What are the risks of getting hiv if ever she was hiv positive who doesnt take any medication. please help.

Answer: 

Hello,

Thank you for your inquiry. From what we gather from the question, you were asking about if you can acquire HIV through your bandaged wound from 15 mL of unknown blood. From the information given, this scenario is determined to be No Risk because the transmission of HIV is not possible in the given scenario.

The scenario mentioned above does not meet the three components of the transmission equation. It does not satisfy the equation because exposure to oxygen renders HIV inactive and the activity does not allow for direct access to the bloodstream.

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