Is diarrhea and frequent urination due to HIV post oral sex?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

I am a 33-year-old male. I had an exposure around five months back with a female sex worker. I had used protection as far as I remember, but oral sex was unprotected. I had taken PEP (Post-exposure Prophylaxis) within 18 hours and continued it for 30 days.

I also got the following tests done:

  • Day 33 - RNA (Ribonucleic acid) PCR (Polymerase Chain Reaction) test - Negative.
  • Day 75 - ELISA (Enzyme Linked Immunosorbent Assay) test - Non-reactive.
  • Day 90 - Rapid HIV 1 and 2 serum test - Non-reactive.
  • Day 117 - P24 duo HIV 1 and 2 - Non-reactive.

I have had chronic diarrhea and gastritis since day 33, diagnosed with a Helicobacter pylori infection. I have taken the Pantocid HP kit for ten days. I started having frequent urination recently, but there is no pain or pus discharge. No genital infection or swelling is observed. What could be the cause of frequent urination?

Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I understand your concern.

The chances of HIV (human immunodeficiency virus) transmission by a single unprotected oral sex act are almost nil unless there are bleeding wounds in the oral cavity. There is no need for additional HIV tests. The HIV tests are repeatedly negative even after three months of exposure. They are conclusive, provided there is no further risky exposure.

The other STD (sexually transmitted disease) tests also show normal results. So, no need to worry about STDs now. The symptoms of diarrhea need not be due to HIV. You can consult your doctor for further examination and management of symptoms, including diarrhea and frequent urination. Frequent urination may be due to diabetes, anxiety, or weather changes.

I hope you find it helpful.

Thank you.

Kind regards.

Patient's Query

Hi doctor,

Thank you for your reply.

My physician says that three months is not a conclusive time. He has asked me to wait for six months. I am worried as I have started getting a sore throat and a cold since yesterday.

Is my p24 duo test conclusive, taken post 117 days of exposure? There has been no other exposure in the interim. Do I need to retest at six months?

Thank you.

Hi,

Welcome back to icliniq.com.

I believe these are conclusive with the given risk exposure and different test results. I do not see any need for further HIV tests. If you are too anxious, you can also go for HIV tests after six months of exposure.

Thank you.

Kind regards.

Patient's Query

Hi doctor,

Thank you for your response.

I started getting painless, small spots (multiple) in my mouth after three months post-exposure, before the last HIV or STD tests were taken. Can you please examine if these are related to any STD or HIV? These are present only inside the cheeks on both sides and are painless.

I consulted two doctors. They told me that these are aphthous ulcers. Are these aphthous ulcers or Fordyce's spots?

Hi,

Welcome back to icliniq.com.

Thank you for the follow-up query.

These appear to be aphthous ulcers. With negative STD (sexually transmitted disease) test results, these may be unlikely due to STDs. You can consult your doctor or dermatologist for examination and management if they persist. It would be helpful if you followed the following activities. Avoid stress. Relax. Take a well-balanced diet with proteins. Take vitamin B supplements if possible.

Thank you.

Kind regards.

Patient's Query

Hi doctor,

Thank you for your reply.

Based on your experience, can you advise if my three-month HIV-negative test can change after six months? What is the window period for all STD and HIV test to be conclusive?

Thank you.

Hi,

Welcome back to icliniq.com.

The window period for detection of HIV antibodies usually is two to six weeks, with a maximum of three months. In some unusual cases (severe immunodeficiency conditions), it may be six months, which does not apply to you. Other STDs are less likely to be found, as no related symptoms are present, and your tests are negative, so you need not worry.

You can rely on these tests. Forget the episode. Relax and get involved in activities of your interest. Do yoga, meditation, and exercise. I hope you find it helpful.

Thank you.

Kind regards.
