HIV transmission via contact with blood

Patient

Q: I went to the supermarket this morning and when I took the change that the cashier handed me, I got into contact with his undried blood on my hand. The blood got onto my nail and cuticle. Although I had no visual cuts, what are the chances of me getting HIV if he were HIV-positive? I am so worried...

Doctor

A:   The chances are there if the person is HIV positive and you have an opening on your skin as well. I always suggest being extra cautious and going and getting tested, even though the chances sound very slim from what you have described.
