HIV Infection

[Dada123]

When i was in Prague I Visited a Night Club on February 19th and had Protedted Sex with a Prostitute. After some time she took out the existing Condom and replaced it with a new one. We continued the Vaginal Sex and suddenly when she checked the condon it had slipped into the Vagina and the penis was exposed . I did not ejaculate inside her. She pulled out the Condom from inside here Vagina. I immediately pulled out and washed with soap and moved from that place. I checked with the Night club about health testing and they said that all the girls are medically checked. But after two weeks i got some yeast infection in the penis ,i applied Clotrizamole on the same , it cleared off in three days. Same time i also got a Lymph node under the armpit enlarged for a day. I also got a Sore throart for two days. After 5 Weeks i went to a Dermatologist and checked for all the STD including HIV . They did a swab test and did a blood test for Syphillis and HIV . All the report came out negative . The Blood test report was as follows

HIV COMBI                : Negative
RPR IMMUTREP             : Negative
Syphillis recomb , ELISA : Negative

The detmatoligist anyway told me to get it checked after three month . I really do not not if i am infected. But by reading your previous replies i get some satisfaction on the Women to Male transmission and also the transmission through a single episode of the Vaginal Sex.

Doc, i wanted to know what is HIV Combi test ( is it the Antigen + antibody test) . If i was infected this result should have shown Positive by five weeks if my assumption is correct about the test. What does the other tests mean .

I am really worried about HIV infecction. If you could clear my questions it will be really helpful. what are my chances of HIV Infection.

Thanks Doc, Can you let me know what are the other blood tests for including ELISA and also clear me of the Yeast infection in about two weeks. is it related to some infection.

Let's assume there is a 10% chance your commercial partner had HIV.  (She probably didn't given the history of regular testing.)  Now assume 1 chance in 1000 of transmission to you if she was infected.  Now assume the testing you had at 5 weeks would have picked up 99% of infections, i.e. there is a 1% chance that if you were infected and the test missed it.  To calculate your odds of actually haveing HIV, those odds are multiplied.  Thus 0.1 x 0.001 x 0.001 = 0.0000001.  That's one chance in 10 million.  Perhaps you will agree with me those are pretty good odds in your favor!

You've got it right about the combination test:  it checks for both the virus itself (the antigen part) and the body's reaction to the virus (antibody).  At 5 weeks, normally one or the other will be positive, often both.  Some experts would advise being retested at 3 months, as your dermatologist told you.  But maybe you'll be comfortable with the current low risk of 1 in 10 million.  But if you're still a little nervous, get retested at 3 months.  In the meantime, rest easy.  You're fine.
