I am currently working in an elementary school with 2nd-5th graders. I am working on my masters in teaching. I am so scared that I am going to get the stomach bug from working here. It is scaring me so bad I don't think I can handle it. I drink a cup of grape juice everyday (does this work?) to prevent the sickness and more than that if I know I am exposed. Does anybody have any suggestions? I am very scared...
