So...my wife is a third grade teacher and she came home yesterday telling me that she had a conference with one of her parents who informed her that the reason her child was not at school yesterday is because he was at home with terrible v* and d*...and she just emailed me from work and he is back at school today. dont people continue to be contagious for several days after symptoms disapear? should I be concerned that she will bring the germs home with her, or on her belongings - then I will risk exposure? or maybe she will get the virus from the child?? then maybe I will get it from her?? I know I worry too much, but I just always try to consider all aspects and possibilities?? should I be concerned do you think??
