I shaved in the morning and I cut the skin on my neck and it bled a little and then there were some cuts and irritation on that area. A couple of hours later, I went to get a haircut and the hairdresser used a seemingly dirty towel to dry off my hair and it came in contact with my neck as well. If there was any blood or bodily fluid on the towel (because it might have been used on other clients after shaving) is there any risk for transmission? Would you recommend getting tested because of this?
