Im pretty sure you cant catch it from her breathing on you. And if you don't wash your hands and touch your face ie. your eyes, mouth nose....there is a slight chance if she didn't wash her hands. Do you think she is being careful and washing her hands after being sick? I definitely would never take food out of someone elses hand and put it in my mouth, especially if she has been sick. That may have not been the wisest decision. I would Lysol everything you think shes touched and things that you touch and start taking preventative measures such as boosting vitamin C and drinking 100% grape juice. Just remember, wash your hands and clean around you....and never take food out of someone elses hands....hang in there!!
