I used my dads hair clippers and nicked a healing scab on my head. There was a speck of blood. i started to worry about if there may have been dried blood on the clippers. I then asked my dad if he had hep c or anything like that. He said definitly not. He was tested a few years ago. I also didnt see any dried blood on the clippers. I asked my dad the last time he used the hair clippers and he said about a month ago. The cdc says that hep c can only survive for a max of four days outside of the body. what do you guys think about my risk? Was there any? What if my dad has a doormant infection (hypothetical i know). and if you guys could especially answer this last question, if there was a miniscule amount of dried blood on the hair clippers, but the blood was from a month ago, is it still infectious? Sorry, im a worryier. Thanks.
