Good afternoon Doctor
I had a exposure with a prostitute 15 days ago and while having relations, the condom broke. It was almost literally 40 second into the act in which I notice that it had broken. I immeditalety stopped and washed of everything. According to her story ,she doesn't have anything and get tested often and it was around two month prior and she is HIV negative. 5 days later i had a negative result in Westren Blot exam and 8 days later another blood test and it came out negative too. I had all the of stds exam done and it came out negative also. A week ago I got Oraquick test and came out negative.
Im not sexually active and the last time i had a sexual encounter was around a year ago. I had a normal cold the past week with swollen lymp glands which is very usual in myself because i suffer from allergies and asthma. Im planing to take the COMBO test this coming week just to make sure i dont have anything. From you POV as a Medical expert, what are the posibilities of contracting HIV ?
