Whether widespread use of masks will help, or harm, during the next worldwide flu outbreak is a question that researchers are studying furiously. No results have come from their mask research yet. However, the government says people should consider wearing them in certain situations anyway, just in case. But its a question the public keeps asking while the government are making preparations for the next flu pandemi C. So the Centers for Disease Control and Prevention (CDC) came up with preliminary guidelines. We dont want people wearing them everywhere, said the CD C. The overall recommendation really is to avoid exposure. When thats not possible, the guidelines say to consider wearing a simple surgical mask if you are in one of the three following situations. First, youre healthy and cant avoid going to a crowded place. Second t youre sick and think you may have close contact with the healthy, such as a family member checking on you. Third, you live with someone whos sick and thus might be in the early stages of infection, but still need to go out. |
