Hello doctor, I am a 26 year old male. I only received unprotected oral sex for roughly two minutes around 46 days ago from a commercial sex worker. I did not have any intercourse. I do not know her HIV status. I had an episode of diarrhea immediately after within the next five days and it resolved after taking Levofloxacin and Lomotil (which I guess was food poisoning as it occurred the very next day). I tested for all STI’s (chlamydia, gonorrhea, hepatitis, and HIV) in 14 days after exposure and all came back as negative. It is an early test for HIV. I traveled abroad for vacation in the meantime and I took Azithromycin 500 g for three days as I had throat ache and mild fever in 20 days after my potential low-risk exposure. I developed a sore on my upper gum and it has been there for 16 days. It is painless now. Also applied Orasore ointment. Recently after 40 days after exposure, I developed small red bumps only in my hand and behind the ear with a sore throat and mild fever. The doctor has prescribed me Amoxicillin antibiotic for five days and Vizylac once for five days. My throat is feeling better now. My questions are:  Am I at risk of HIV? Are these recurring mild fever and sore throat acute HIV symptoms? Is the sore in my mouth a concern? As I have had an eye transplant and my immune system is weak would I have contracted HIV from my exposure?
Hello. I have noted your concern. Unprotected insertive oral sex with an HIV positive woman has a negligible/non-existent risk of transmission of HIV for the male partner unless she had oral sores or blood mixed saliva or bleeding gums which might increase the risk. You have had two episodes of a sore throat after this sexual encounter which can be because of seasonal flu and change in weather. I have a few questions.  The sore on your gum could be more of a dental problem rather than an STD. I suggest you take oral Metronidazole 400 mg, thrice daily in addition to the Amoxicillin that you are already taking. Also apply Metrogyl DG gel (Metronidazole), twice daily. Regards. For more information consult a dermatologist online -->
