My dad has Hep C but i think his non infectious is this possible? i got into a punch up with him and i think i punched his earing and i cut my self, i don't know what caused the cut on my knuckle. it was a small graze but it did bleed i don't think it was deep enough into my blood stream? and i looked at his earings the next day and i don't see any blood on them? am i at risk for Hep C ?
