I know this may be dumb, but how easy is it to catch Hep C (or HIV) from dried blood. I had blood taken earlier and the attendant rubbed her finger on my vein before gloving and then put the needle there. She was using a pen patients typically use to sign stuff after getting blood drawn. Is there any way a patient could have touched their puncture spot, then the pen, then she gets it on her and passes along? Writing it sounds incredibly stupid, but anxiety can be illogical. I also handled my phone a lot after using this pen and my son played with my phone, then put his fingers in his mouth.
Logically, I think there's zero chance of there being a risk, but it would do me good to hear someone else agree (or disagree).
