Hi. Your website is very useful for people who are worried like me.
I have a question that needs your help. I eat an ice cream in the refrigerator for 2 hours, if the ice cream stick is bloody and I'm injured in my mouth, I'm at risk of hiv exposure.
I took the road and was shot in the face by unknown water. If the liquid is hiv blood or viral fluid, then I have a risk of hiv exposure.
Thank you for your inquiry. From what we gather from the question, you were asking about the risk of acquisition of HIV from exposure to infected water and infected ice cream stick. From the information given, this scenario is determined to be No Risk.
HIV is not transmitted by food. Even if the refrigerated ice cream stick had some dried blood it does not aid in the transmission of HIV, as HIV does not survive long outside the human body (such as on surfaces)  and also the stomach acid would help to destroy the virus. Contaminated water does not serve as a source for HIV transmission, if you take infected blood into the mouth then only you are considered to be at risk. The above scenario does not pose as a risk for HIV transmission.
Only certain body fluids—blood, semen (cum), pre-seminal fluid (pre-cum), rectal fluids, vaginal fluids, and breast milk—from a person who has HIV can transmit HIV. These fluids must come in contact with a mucous membrane or damaged tissue or be directly injected into the bloodstream (from a needle or syringe) for transmission to occur. Mucous membranes are found inside the rectum, vagina, penis, and mouth.
Recommendation: No need for HIV test with the scenario provided, refer to a physician for other health related questions.
