Dear Helpline Volunteers 

Really appreciate your hard work to answer the questions from the public. I have a toilet paper related question about it is not exactly the same as the archive ones. Please kindly review my questions:

I accidentally wipe my vagina area with public toilet with wet spot on it. The wet spot is not bright red at least for easier recognize but also not totally colorless. I am worried what if it is some blood and other body fluid mixture. I have two pimples around my vagina area and I just scratched it to a little bit break one night before. Am I at risk? do I need to do test? I appreciate your answer.

Thanks
Regards

Hello,


Thank you for your inquiry. From what we gather from the question, you were asking about the possibility of HIV transmission through contact with wet toilet paper that was possibly contaminated, with blood or another body fluid mixture, to your vaginal area. From the information provided, this scenario is determined to be No Risk (HIV transmission is not possible in the given scenario). 

HIV (contained in a body fluid such as blood) is extremely sensitive to the environment outside of the body. Exposure to oxygen in an environment outside of the body causes HIV to undergo a rapid reduction in concentration (1). From the CDC, HIV outside of the body that is drying on a surface (in this case being the toilet paper you used), has a rapid (within several hours) reduction in concentration of 90-99% (1). Therefore, this situation does not meet the requirements for the HIV Transmission Equation (see the image below) as the fluid that was in contact with your vaginal area did not have sufficient access to your bloodstream through a High, Low, or Negligible Risk activity. 

For these reasons, you are not at risk of HIV transmission. Contact between environmental surfaces and fluids with your vaginal area/the pimples you have described does not warrant an increased risk of HIV transmission, due to the above reasons. Although you do have an open wound (i.e., your popped pimple), the equation will not be satisfied under these circumstances. 

Recommendation: There is no evidence or no documented cases of transmission. Refer to a healthcare professional for more personalized answers or other health-related questions.


All the best,

AIDS Vancouver Online/Helpline, Shirley
