Hi, I have always thought I would like to be a nurse, but I tend to get sick (contagious illnesses) a little more often than other people. I was wondering, as a nurse, when is it best to call off from work due to illness? I mean, I would always be worried if I had what seemed to be a cold or a flu, for example, that it would get patients sick, but I wouldn't want to call off too often either. Can you wear a facial mask when you are sick to minimize the likelihood of getting patients ill, or what do you do? Thanks.
