Not sure if anyone can help with my question but its worth a try. I went and got blood work today. I told the girl I bruise easily so she made a small cotton ball and put it under my bandaid without gloves on after she put a bandaid on another lady with out gloves on. She did use hand sanitizer after putting the bandaid on the otehr lady. If she got blood on her finger then made a cotton ball for me and put it under my bandaid could some sort of infectious disease be passed that way?? let me know thanks!
