I had a fingering exposure where i fingered a prostitutes virgina possibly after biting nails because i have a habit of nail biting. Though i did not notice any bleeding or pain from finger after fingering incident and the virgina was not wet. I have some neck pains and groin but no sign or feeling of swollen lymphnodes. I just noticed a bump on my groin which i figured was a pimple because when i squeezed it, it removed pus and some blood. I did an oral hiv test at close to 6 weeks (just about 2 to 3 days to 6 weeks) and it was negative.

What are my chances of my results not changing to positive? Whats the difference between hiv lymphnodes and lymphnodes from different infections such as an injury just incase it was a lympnode in my groin?

Hi there,

Thank you for your inquiry. From what we gather from the question, you are asking about the risk of acquiring HIV after engaging in fingering after biting your nails. From the information given, this scenario is determined to be Negligible Risk (there is no evidence or no documented cases of transmission, however, there is a theoretical possibility of transmission under certain extenuating circumstances).

In order for transmission to occur, a number of requirements must be met (see below). 
Helpline Transmission Equation .jpg 
HIV transmission requires the presence of HIV positive fluid (such as semen, vaginal fluid, pre-cum, rectal fluid, breastmilk, etc.), coupled with a High, Low, or Negligible Risk activity, that provides the virus with direct access to the bloodstream.

In the scenario you described, you had superficial wounds on your fingers (i.e. small skin breaks that are not actively bleeding), therefore it is highly unlikely that HIV particles had direct access to the bloodstream, meaning the transmission equation is not satisfied, and your risk of transmission is Negligible in this case.

Rapid HIV tests are 99.6% accurate, therefore your results should be interpreted as negative (1).

Recommendation: There is no evidence or no documented cases of transmission. Refer to a healthcare professional for follow up regarding your symptoms.
