I was shaving some hair from my neck and grazed a part of my skin. The skin become red and it felt a little irritated. If I rubbed my fingers over the area it would hurt a little. It was not bleeding actively, i.e. when I touched it with my fingers no blood came on my fingers. However, it was grazed and had a few minor scratches (and maybe little cuts like little red lines). I asked my roommate to examine it. He felt the area with his fingers. I then noticed that my roommate was occasionally rubbing a wound on his arm with his fingers. It was a partially healed open wound that was not actively bleeding at that time. However, if you looked at it you could see that it was reddish and a little bit wet. As my friend was rubbing his wound just before I asked him to examine the skin on my neck. Could this be a risky situation for HIV transmission? My friend is of unknown HIV status. He has been quite careless with some things and I have been urging him from quite some time to get tested.
