first of all, congratulations for your work. You are really helping people and making a difference.

I would like to ask you the following question, if possible.

Two months ago, I had a sexual encounter with a women that I’ve never seen before. We didn’t had condoms and so we just had some fingering and oral sex. She gave me a blowjob and I did cunnilingus on her, just licking around the clitoris for some 5 minutes. 

There were no open wounds or sores on my fingers or on my mouth. However, some years ago I was diagnosed with periodontitis. The disease is under control and I have no bleeding gums for a long time. 

What made me anxious was that happened afterwards.

10 days after, I begun feeling sick, with headaches, chills, loss of apetite, general weakness and a running nose. I had no fever, nausea, diarrhea, sore throat or swollen glands.

But 4 days later (14 days after the exposure), a rash appeared all over my thorax. It was a maculopapular exantema, and it was not itchy. This rash disappeared almost completely in just two days. 

Probably it is important to mention that on the day before the first symptoms appeared I’ve started to taking two meds that I’ve never used before: Metamizol Cinfa and Arcoxia. I’ve stopped taking these meds on the day that the rash appeared, because I thought it could be an allergic reaction to the pills.

3 days later I went to the doctor and she told me that the rash was probably caused by those medicines. She also told me that I had a respiratory infection and gave me antibiotics to deal with with. I asked her about Acute HIV, without telling her about my recent possible exposure, but she dismissed that possibility without further explanations.

In 2 or 3 days, the antibiotics worked and the symptoms (mainly difficulty on breading, catarrh and running nose) disappeared. 

However, I cannot stop thinking if these symptoms were not from a pulmonary infection but from ARS. So, I would like to ask you the following questions: 

1. Could I get HIV from getting a blowjob and for doing cunnilingus, as described above?

2. Having periodontitis is a risk factor, even if I have no bleeding gums or any kind of cuts or sores?

3. The symptoms I had could be ARS?

4. Should I get tested?

Thank you very much for you help. 




Thank you for your inquiry. From what we gather from the question, you were asking about the risk of HIV transmission from receiving oral sex without a barrier and performing cunnilingus with periodontitis. From the information given, this scenario is determined to be Low Risk (Evidence of transmission occurs through these activities when certain conditions are met).

In order for HIV transmission to occur the three components of the transmission equation (pictured below) need to be met. If vaginal fluids were to enter an open sore present due to your periodontitis transmission of HIV may be possible (1). Therefore, if there were open sores present in your mouth the cunnilingus mentioned above does meet the three components of the transmission equation.
Helpline Transmission Equation .jpgPeriodontal disease is a risk factor for HIV transmission because it causes open lesions and activated inflammatory cells which could favour the transmission of the virus (2). If you have your periodontitis under control where you do not have bleeding, inflamed gums your risk of transmission would decrease.

In response to your other question about your symptoms, the symptoms for initial HIV infection are very broad and can have many different causes. Due to the fact that you were diagnosed with a respiratory infection and given medication and it subsequently cleared up I would not be concerned. If you are unsure or worried I recommend that you follow up with your physician.

Recommendation: Refer to a health care provider for HIV testing
