HIV Question

Dear experts, I am from China.
10 days ago, a friend drunk one bottle of cow yogurt mouth to mouth (which mixed with oligosaccharide, milk , water, citric acid, lactic acid and so on) , not drunk the yogurt up, then put the left half  bottle of cow yogurt on the table. 5 minutes later, I drunk up the half bottle of cow yogurt he left (mouth to mouth). He and me both had canker sore and a little bleeding that day. He was tested hiv+ yesterday. My questions are as follows:
1. How long will  hiv virus live on the bottle mouth stained with yogurt and in yogurt? Does hiv virus die immediately on the bottle and in yogurt?
2. Is 5 minutes enough for hiv virus to die on the bottle and in yogurt?
3. I read the answers of drinking coffee by experts here, does hiv virus live longer in yogurt than in coffee and in water and in other beverage?
4. Will I be infected hiv this way? Is anyone you know infected this way?
5. Do I need test? I want to get married next week, Can I get married without test?
Thanks sincerely. Please answer me objectively, not console me and relax me.

Welcome to the forum.  Thanks for your question.

I understand your concern; situations like yours are unnerving.  However, after you learn some basic facts, you'll find you need not worry at all.

First, oral exposure to HIV rarely results in infection.  Part of the reason is that saliva and stomach acid and enzymes kill the virus.  Second, family members of HIV infected persons, living in the same home for many years and regularly sharing kitchens, eating untensils, cups, etc never become infected.  Third, almost nobody with new HIV infection has no apparent risk factors -- that is, all of them have had unprotected sex, shared drug injection equipment, or other obvious factors.  Those that deny such exposure usually are lying, or had exposures they forgot about.  If events like yours could explain HIV infection, obviously there would be many people with HIV but without the typical risk factors.

To your specific questions:

1-3) These all ask about how long HIV will or will not survive, i.e. the biological reasons why there is no risk. This really doesn't matter.  The important thing is that such exposures never result in HIV transmission.  The biological reasons for it are unimportant.  I have no idea whether HIV may survive in yogurt versus coffee, or on a yogurt bottle.  It just doesn't matter.

4) No, you will not be infected.  You need not worry at all.  Don't have sex with your friend, and don't share injection equipment with him or her.  Aside from that, don't worry.  You can shake hands, hug him, share meals, and let him use your toilet or shower.  You will not be at risk.

5) There is absolutely no need for you to be tested on account of this event.  Of course, if you have had any unprotected sexual exposures or other risky behaviors, it would be wise to be tested before marrying.  But definitely not because of your infected friend.

I hope this has helped.  Best wishes--  HHH, MD

I drunk  the half bottle of cow yogurt he didn't drunk up which he put on the table, We shared the same bottle of cow yogurt mouth to mouth.We both had canker sore and little bleeding on lips that time.

Please answer the last question i concerned. Hiv virus in a drop of blood exposed in air and hiv virus in yogurt, which will live longer?
I think it is not diffcult for you.
I just want an exact answer by which one.

I assume the virus would survive longer in yogurt than in the air.  But as I said above, it doesn't matter.  Either way, you are not at risk.
