Question on risk (for teak, etc...)

Greetings, I have been reading this community for a bit and I had a question about a risk myself. So I hope for some insight as opposed to an "are you serious" or "move on" type of answers like I've read several times.

Lets say a person has a papercut type break on their fingertip and in the process of flushing the toilet gets actual semen on that exact location from somebody who has obviously used that restroom prior. The bodily fluid was washed off immediately. The timeframe for the fluid being on the toilet handle would have been AT LEAST 5 minutes at the very minimum. So the questions are...

1. What type/how much of a risk would be associated with this?
2. Should one consult their MD about this?
3. How long would a virus like HIV survive outside the body in semen on a toilet handle?

Your time is appreciated

1. Zero
2. No
3. It doesn't stay active outside its host.

So even if it's only been 5-10 minutes? Which I have no idea if it was that or much longer...I am just assuming minimum times here...the viris is no longer active in a fluid like semen?

You cannot contract HIV from environmental surfaces.

Well I do thank you for your responses..one final wrap up I suppose, you say a person can't contact the virus from an environmental surface? I guess I wonder why this is...how does the virus become "inactive" after being exposed to the surface?? One would think it would be able to survive for hours and still be able to infect?

As soon as the virus is exposed to air,temp change and ph changes it causes the outer shell of the virus to become damaged and it becomes ineffective to cause infection.
