Yesterday I learned that a man I ve been sitting next to in class, week after week, has crusted scabies. He had it analyzed last week & came with his head shaved. Yesterday he had been treated and told me when I asked him how he was, that it is scabies for sure. I came home to Google scabies and learned that it s highly contagious. I don t touch him but he gave each of us a paper report last week, so we all got contact thru the paper. How shall we protect ourselves?
