Chances of contracting hep c?

I work in health care and had an eraser sized drop of blood (from a pt with known active hep c) land in my nose. I immediately wiped it out, then rubbed with rubbing alcohol, then iodine. Of course I went to the ER and reported it, had a complete work up (as did the pt). I'm just wondering what my chance of contracting the hep c is? I will get re-tested in 4 weeks, and again 8 weeks after that, but I would like some insight now. Thank you
