Hep c requires blood to blood contact hep c infected blood must enter the blood stream on an uninflected person. However that being said people with hep c are advised to avoid sharing personal hygiene products like toothbrushes, fingernail clippers, and razors with others. So probably not the best practice to share a cleaning cloth between people. But I would worry too much hep c is not easily transmitted.
Thank u that makes me feel better. I was only so concerned because she was teething and the guy had some wounds not totally healed. Pedia saod not to.worry to much since there was no blood on the towel.
