Question about transmission

[bumblebee2513]

Hi Doctors,this forum is great, thanks for all the useful advice I've read. I've been worried about something for a while. I've read in threads one shouldn't worry about HIV transmission from toilet seats. I just had concerns about if a piece of toilet paper was sitting in the bowl (on the ceramic and not inside the water, i.e.it never flushed away or got contact with water) and if someone urinates on it, can that splash the blood up into a mucus membrane?
Also I once used a toilet very quickly after my friend who had her period. I guess it was still filling up, or flushing away, but I felt spray on my body and worried that could cause transmission. (I had my period as well but i guess its not significant).
I know these Qs show signs of anxiety but I became scared as she's talked about having dated guys she thought may be gay and I don't know what she did with them etc, and I'm worried about bringing HIV into my relationship or home.

Welcome to the forum.

Urine contains little if any HIV, and also inhibits the virus.  Urine contamination or exposure probably never is a source of transmission. But even if you were talking about blood, the sort of events described here could not result in HIV transmission.  Probably nobody in the world has ever caught HIV in a public toilet unless they had unprotected sex or shared drug injection equipment while there.

So no worries, no need for testing, and no danger to your sexual relationship or in your home.

Of course it applies to you.  Do you see any ohter people in this conversation?  And even if you were unsure, please re-read my original reply, especially "Probably nobody in the world...."

Thanks Dr for your reply.

At the risk of being very frustrating, I wasn't sure if your response was intended for my thread or someone else's - I wasn't sure if the word 'environment' covers my situation.
Sorry again

[H. Hunter Handsfield, M.D.]

Blood exposure in the environment probably has also never led to an HIV infection.

Many thanks Dr for your help!
I realised my writing was confusing - I meant to say that I was worried about blood being on toilet paper or around the toilet bowl AND not having been contacted by water. And then getting some kind of splash from it if I used the bathroom (i.e. my urine splashed up the other person's blood).
But I think if my understanding is correct - the blood still couldnt infect me even if it didnt hit the water

Promise this is my final comment as I know you have more important Qs to attend to!
