First of all, I would like to thank you for everything you are doing for us. 

Please help me assess my risk 

Yesterday I was outside with a friend repairing his car, the car hood was open and suddenly he hit his head on the edge of the car hood. I immediately touched the car edge where he hit his head in order to check if it was sharp or not. I didn't see any blood on it (maybe some micro drops) 

Two minutes after I washed my hand with perfumed liquid soap and some drops of liquid bleach.. For information I haven't any cut in my fingers. 

One hour after that, I felt some pain in my anus(maybe hemorrhoids) and I directly put my finger in my anus to check what is hurting me (the same finger which had touched the car hood). I didn't push it into my anus but I touched the hole and scratch it a bit . Now I'm really stressed about it, please help me assess my risk and answer my questions 

1-is there any risk to catch hiv? In case I didn't wash my hand well. 

2-any testing is required in my situation? 

3-may I continue to have unprotected sex with my wife after this exposure? 

4- I didn't see any blood in my fingers after touching the car hood and after touching my anus, is it safe to resume my life without any worries? But what if there was some micro drops which I did not see? 

5- do you think it is irrational fear and I am worrying needlessly? As I have hiv phobia. 

6-may I forget this exposure and move on with my life without any fears of hiv (no matter my friend status), may put it behind me and never think about it anymore? 

7-should I take pep as it happened yesterday? 

8-is a perfumed liquid soap with water kill immediately the virus? I mean if the drops of liquid bleach were not enough to kill the virus (because I used some drops only) 

I really trust you, please help me with the exposure in order to know what I have to do

Thank you in advance sir

You shouldn't be at all worried. Nobody in the world has become HIV inftected by exposure to blood or other infected fluids in the environment. Even if your friend has HIV, there is no risk from things like this. To your specific questions:

1) No risk -- there would be none even if you hadn't washed your hands at all.

2) No testing is needed.

3) You can safely continue unprotected sex with your wife.

4,6) These all the same question in different words. vYou indeed should 'resume [your] life without any worries" and forget this event. (It was not an "exposure"!)

5) Your fear isn''t completely irrational, since you apparently have an inflated view of HIV risks. It will only be "irrational" if you continue to be fearful after you have read my replies!

6) Any soap instantaneously kills HIV.

Thanks for the thanks in advace. I hope this reply settle your fears. Let me know if anything isn't clear.

Many thanks for your quick answers. They really helped me.. I will do my best to not stay fearful after your replies. Maybe now I will ask for some "what if" questions to avoid them coming in my head later... I really want to move on with my life and forget hiv definitely. 

1- Sir please (this not a what if question, just asking for clarification). When you said "nobody in the world has become hiv infected by exposure to blood in the environment" I'm afraid you were only talking about the first part of my situation "when I immediately touched the car hood after my friend hit his head" I had no cuts so I think it's safe.. But were you also talking about touching my anus one hour after touching my friends blood? 

2-when you said sir "even if you hadn't washed your hand at all still no risk" does it mean that one hour is more then enough to rend the virus died and inactive? 

3- if I pushed my finger into my anus and I didn't pay attention, is it still no risk? 

4-if there was any pimple or irritation in my anus (the cause of my pain there) and I touched it with my finger, is it still no risk? 

5-all in all, may I be sure that one hour is enough to kill the virus. And all imaginary scenarios in my head  will stay no risk? 

6-after reading above scenarios (and what if qst). Is testing still no needed at all? 

7- last question sir, sorry for repitition, may I forget all this event, no matter which scenario come to my head? No need for concern nor for testing nor for pep nor for abstaining from unprotected sex with my wife? 

Finally, is this thread will still open even if I don't ask third follow up? Or will be closed after days or months? 

Thank you sir. 

2) It means that even without washing, HIV would not be caught by an event like this. Washing hands after blood contact is a good idea of course -- but if you had forgotten to wash, you still would not have been at risk.

3) Maybe if you had this contact immediately after contacting HIV infected blood with that finger -- within a minute -- there could have been risk of transmission to the anal partner. Not possible any later than that, after blood has dried -- and especially after washing.

4) Still no risk.

5) Yes. HIV is dead within a few minutes of drying or exposure to air. Or instantly with soap and water.

6) Still no risk and no need for testing.

7) Correct. If any other scenarios come to mind that worry you, the first thing you should do is come back to the forum and re-read all your questions and my replies. I am confident you'll find your new scenario questions already are adequately answered. Avoid the temptation to ignore any further "what if", "yes but", or "could I be the exception" questions. To avoid HIV, all you need do is not have unsafe sex and to not share drug injection equipment with other people. If you ever have friends or family members with HIV, you can safely share toilets, kitchens, eating utensils, and drinking cups; and you can hug and this them as any family member would. HIV isn't very easy to transmit!

This is my last follow-up, I will do my best to cover all my worries and clarify other points. 

1-sir, when you said "nobody is known to have acquired hiv outside any sexual exposure...." what's the difference between my event and a sexual exposure? I mean I put my finger which had probably infected blood (from my friend) into my anus to inspect hemorrhoids or something else which was hurting me? 

2-when you said sir,".. and a few other specific events." what did you mean sir? 

1. Having unprotected vaginal sex with an HIV infected woman has only 1 chance in 2500 the man will become HIV infected (which is why many spouses of infected people never catch it -- which perhaps you didn't know). Even though considered one of the highest risk exposure, the actual chance of transmission is low. If it's that low when a load of HIV infected semen is injected deep inside the body, how high can it be for the sort of event you are worried about? The answer is zero for all practical purposes. For infection to take hold, lots of virus must gain access to certain cells that are deep inside the body. Sex does this (often, but not always); the kind of exposure you had does not.

2. I don't have time to list all the other rare possibilities that can result in HIV transmission. One of them is transmission to a baby during delivery by an infected mother; and nursing babies exposed to mothers' infected breast milk.

3. This appears to be an English understanding issue. You'll have to figure it out or find a friend who understands.

4. Repeat question. No risk.

5. i agree with the CDC statement, except that the virus usually dies within minutes. "Several hours" only applies to wet and warm conditions.

6. That is correct.

7. I already said you can forget the event. If he didn't even bleed, I don't understand why you thought there might have been risk and why you needed to ask your original question.

8. YES.

You came to this forum convinced you were at risk for HIV. I have done my best to reassure you by explaining that there was no risk and the reasons you were not at risk. But you keep arguing -- or at least not trusting my replies. It's as if you are hoping I will confirm there was risk. But this isn't a debate.

That concludes this thread. I do hope you'll be able to move on with no further worry. Note that repeated questions on the same topic are not permitted. Please do not post any more questions about this event and your concerns about HIV risk. There is nothing you can think of that would possibly change our assessment of your situation or our advice. Thanks for your understanding.

Best wishes and stay safe.
