HIV from scratching scab from mosquito bite

Hi Doctor.  My question is pretty simple.  I hope you can answer it.  I fingered a girl of unknown status.  Afterwards, while walking to the bathroom, I scratched a scab from a mosquito bite which started to bleed with the same hand I figured her with.  Assuming there is vaginal fluid on my fingers, do you think HIV could be transmitted when I scratched the scab to the point of bleeding? Please help.  I've lost some sleep over this.  Thank you doctor.

If HIV could be transmitted that easily, we all would have been infected 10 years ago.  There is zero risk from that sort of exposure.
