What Causes Severe Diarrhoea After Unprotected Anal Sex?

Posted on Mon, 13 Jul 2015

Question: Hello doctors I had a high risk encounter unprotected anal on May 8th 2015. 4 weeks after the encounter I experienced 1 day of diareah and 1 week of awkward soft stools. This entire time I'v been worrying since the encounter. So far no fever just s few hot flashes. I have tested the following

2 weeks - APTIMA hiv1 rna by TMA - not detected (negative)

5 weeks- negative labcorp Hiv-1 rna - not detected(negative)

5 weeks- 4th generation Combo ab/ag - negative

What are the chances of my results becoming a positive at
The 12 week mark? And do I even need further testing? The anxiety is effecting my work life.

Thanks

Hi
Thank you for query. I am Dr Bharatesh D Basti answering your query.
Welcome to health care magic.I have gone through the details.
The chances of transmission by single unprotected intercourse is low.The person may be negative too.You can relax if you know the HIV status of the person.
The HIV 1RNA test is negative after 10 days is almost conclusive. Also combo test is negative too.
The chances of HIV is almost nil.
The possibility of results turning positive later is almost nil.
You can allay fears.Get an Antibodies test after
12 weeks for final relief of your anxiety.
You can get back for any clarification.

Thank you so much doctor! So my symptoms i have experienced are probably just out of fear and stress? Also have you ever saw a negative 5 week duo turn positive at 12 weeks?

Thanks doctor!

Hi
Thank you for follow up query.
The symptoms may be due to anxiety or simple infection.
It is not specific to HIV.
RNA PCR is more reliable than duo test.Unlikely to get positive test results later.

Okay sorry doctor just for clarification both my RNA tests are probably considerd more then 95% reliable by themselves as HIV rapidly replicates during the first weeks of infection? I have attached my results for you to view if possible also i will get the 12 week test just to clear my mind
