Hello,Doctor:
    Thank you very much for reading my letter.
    
    I am chinese.so my enlish is not very good.if I have some offence,please forgive me.
    
    I have a question about HIV want to consultation you,because I belive you are authority.
    
    I have read the article on USA CDC wetsite, and I know drying of even high concentrations of HIV reduces the amount of infectious virus by 90 to 99 percent within several hours. But I want to know how long does hiv virus live outside in a common patient's blood or vaginal fluid.
    
    I want to know it is because my instance is special. I made love with Miss A without condom, after about halfhour, I made love with Miss B without condom, I want to kown if Miss A is  hiv patient, her vaginal fluid or blood was on the surface of my private parts, after halfhour, CAN this fluid or blood infect B? Maybe you have guessed B is my girlfriend, that is why I urgently want to know how long does hiv virus live outside in a common patient's blood or vaginal fluid. PLEASE help me analyse the the possibility of infection to B.

    THANKS AND BEST REGARDS!
    Please accept the highest gratitude from a  Chinese

Welcome to our Forum.  I see that you asked the same question on the HIV Community site several weeks ago.  My answer is the same as the one you have already received - your second partner (B) is not at risk from HIV from carriage of the virus on the surface of your genitals from one partner to the other a half hour later.   HIV lives only minutes, at most outside of the body.  Precisely how long depends on many things such as temperature, humidity (drying) and the duration but I can assure you that in the situation you describe, partner B was at no risk for infection.

A more important question however is your own risk.  While your own risk is low, having unprotected sex with an infected or possibly infected person puts you at risk for acquisition of HIV.  Please use condoms.  EWH

No, given those test results you do not need further testing.

Less than 50% of persons who acquire HIV get symptoms from early infection. This is the reason testing is so helpful and worrying about symptoms is not.

Glad to help. Take care. EWH

Last answer.  This makes no difference.

Further questions will be deleted without comment. EWH

Dear doctor,  I suddenly bethink of another detail.  AFTER I make love with A,  I had a shower bath,  I wonder weather this have  effect  on you conclusion.
THANK YOU VERY MUCH!

This is not a debate.  HIV does not live outside of the body more than a few mintues.  It would not survive half an hour.  You are not at risk.

Please, no more "what if" or "But could it...." questions.  they are a waste of your time.  No risk.  EWH

Dear doctor:
  When I read your reply again,I have an important doubt,If you don't know how long  hiv virus live outside,why you can assure  my partner B was at no risk for infection.
    I have no doubt about you authority,I just want to know why,Please forgive my offence!
    Thank you very much!
