Q. What are the chances of getting HIV after protected sex?

Hi doctor,

I am a 26-year-old male. I had protected sex with a sex worker a month back. I used one condom, she gave oral sex and post that had vaginal sex for 5 minutes. Once I finished off, I went to the bathroom and got cleaned off. I could not see any tear as such on the condom. I just washed my penis and got back home. The same night after 2 hours I pulled my foreskin behind to clean my penis with soap. The frenulum got too tight and tore. It started bleeding. I washed my penis and let it heal for 2 weeks.

What are the chances of getting HIV from what had happened? I do not have any symptoms. Just had fever for a day and now I have a common cold. On the 15th-day post exposure (yesterday), I went for the HIV PCR RNA yesterday. The results are yet to come. Will the torn frenulum give chance for HIV virus to get in after 2 hours? I am feeling very anxious and stressed out. I really need your guidance. Please suggest what I need to do to rule out HIV and live a normal life. Please help.

Hi,

Welcome to icliniq.com.

The chances of transmission of HIV with given description is almost nil. The HIV test is likely to be negative. If the test is negative, it is almost conclusive provided there is no further risk exposure. The chance of test result coming positive later is almost nil. You can go for HIV antibodies tests after 3 months exposure to have final conclusive results to relieve your anxiety.

Hello doctor,

I really appreciate your quick response. There was no further exposure. Can I take this HIV RNA test result as conclusive and not retest after that? I just wanted to know how accurate this test is after 15 days of post exposure. Is it more than 95% accurate? And are there chances of false negatives?

Hi,

Welcome to icliniq.com.

HIV RNA PCR is more than 95%-99% sensitive after 12 to 14 days of exposure. It is almost conclusive. But, it would be better to go for HIV antibodies tests after 3 months exposure to have final conclusive results and to relieve your anxiety.

Thank you doctor,

I got my PCR RNA results but they have only done it for HIV 1. It has come back as not detected. I have attached the report for your reference. Lymphocytes are slightly high. Is this a bad thing? Please give me your feedback. I also want to know the following:

  1. Do I need to test for HIV 2?
  2. How safe am I with respect to acquiring HIV?
  3. Do I need to test for STD? I do not have any kind of symptoms.

Please suggest what I need to do to get this done and forget about this.

Hi,

Welcome back to icliniq.com.

The chances of transmission of HIV with given description is almost nil. HIV 1 PCR is negative. It is almost conclusive (attachment removed to protect patient identity) HIV 2 is usually rare. You can get HIV 2 RNA PCR too if you desire. It is rare.

Though the chances of tests coming positive later are nil, it is better to go for HIV 1 and 2 antibodies tests after 3 months exposure for final conclusive results.

You can get other STDs panel test if you desire like VDRL, HSV 1 and 2, IgM and IgG antibodies tests and HBsAg (hepatitis B surface antigen) as a routine.

For more information consult a community medicine physician online --> https://www.icliniq.com/ask-a-doctor-online/community-medicine-physician

Thank you doctor,

Can I take the STD panel test now? It has been 3 weeks since the exposure. I need not repeat it later on, is it? If I do a HIV 2 PCR tomorrow and if it comes as negative, will I be 95 % safe?
