Thank you for reading my question. I was at the grocery store, at the self checkout and began checking out. Once I had rung up, I looked down and saw a bunch of dime to quarter size droplets all over the area for scanning. I could not tell if it was blood or not, but it looked like it could have been. I was not bleeding, so it may have been a person right before me. I believe that in scanning my purchases I ran my shirt sleeve through it (maybe my hand). My worry, however, is later, at home, my one year old old cut the side of his nose and was bleeding. I do not live far from the store. The cut went the length of his nostril or more and was bleeding, and looked rather deep (I have no idea what he cut it on). I cleaned his nose with a wipe. In tending to him again, he turned his face away and into my shirt sleeve, where I fear I may have had blood transfer from the store. Should I have any concern for him? or my self for that matter, but my biggest fear is for my baby.
