Dear Vancouver volunteer, Thanks for answering my previous post. After I post my question, I realized that I forgot one scenario. I know toilet problem has been asked again and again. I just have one more special case want to double check on your opinion.
I once used a airpot public toilet. It is a busy hour so people used that spot one by one in queue. I may sit too front while pee. My urine hit the toilet bowl surface, the porcelain part and flash back on my annal area. I did not see obvious blood at that area. But not sure about other body fluid like vagina discharge etc. What if there is some body fluid from the previous lady who just left the spot before I entering in and it come to my annal area with my backsplash urine, am I at risk? I did not get chance to wash my under immediately. Just use paper to wipe the wet part. I don't have any bleeding cuts around my annal area but I have tiny annal fissure a week ago, that may not been totally healed. And since I just delivered a baby not a long time ago, my immune system may not be as strong as normal people. Thanks
Thank you for your inquiry. Form what we gather from the question, you were asking about a possibility that broken skin on your anal area was contaminated by vaginal fluid left on the toilet seat from a previous lady at an airport public toilet.
From the information given, this scenario is determined to be of No Risk (transmission of HIV is not possible in the given scenario).
The scenario above does not meet the three components of the Transmission Equation. For a risk to exist, a specific HIV+ fluid must come into direct contact with the bloodstream of an HIV- person. In this case, there is no possibility of infection in your anal area because mucous membranes (such as in your anus) are covered with thick layers of cells that are tightly joined together to protect certain microorganisms from entering the body (1). Furthermore, HIV undergoes a rapid reduction in concentration when exposed to oxygen or environmental surfaces. In this scenario, the exposure of the fluid you have described to oxygen would have essentially rendered any HIV inactive, effectively reducing the risk of HIV transmission to zero (2). Toilet sharing is not an activity that leads to transmission therefore does not meet the transmission equation.
Recommendation: There are no evidence or no documented cases of transmission. Refer to a healthcare professional for more personalized answers.
