Here is the deal. I have been sitting in a CNA class for the last 3 weeks next to a guy who I just found out has TB. He says he is a carrier and can not spread the infection but I read that there are no carriers to this disease. He did say that he just found out last week about it while getting his physical and is now on medicine for the next 9 months. Shouldn't he have told the instructor and the class? Am I as well as everyone else around him at risk for getting TB? I have read a bit but it is still kind of confusing where the line is drawn.
