1) Somewhere around 99% But consider the odds: Say there is a 1% chance your partner had HIV. Then esttimate a 1 in 1000 risk you caught it. Then a 99% accurate test. Your odds of having HIV at this point are 0.01 x 0.001 x 0.01 = 0.0000001. That's 1 in 10 million. According to a statistic I heard on NPR today, he odds you will be struck by lightning someday are 1 in 28,000. That's 357 times higher than the chance you have HIV.
2) No recurrent yeast infecttions in women rarely is a sign of HIV.
3) No, you do not need further testing.

I believe that Dr. Handsfield has said that recurrent yeast infections aren't a strong symptom of HIV.
You have yeast in your vagina most, if not all the time, but it's kept in check by the other little organisms. However, sometimes something happens to alter the balance of bacteria, allowing the yeast to overgrow. Are you on the pill? Taking antibiotics? Those can be big culprits. And are you sure you're getting rid of each yeast infection, rather than repeatedly treating the same one? There's at least one strain of yeast, I think it's called candida glabrata, that is pretty resistant to treatment. I think I'd ask your doctor to follow up on this. Having had more than my share of yeast infections in the past, I know how much this sucks. I hope you feel better soon!
