Will it help to wear a mask?

Information on the effectiveness of facemasks and respirators for decreasing the risk of influenza infection in community settings is extremely limited. So, it is difficult to assess their potential effectiveness in decreasing the risk of Swine Flu virus transmission in these settings. However, a well-fitted, FDA-approved mask together with other preventive measures MAY reduce the risk of contracting the flu. Those who are sick or caring for someone who is ill should consider using a mask or respirator if leaving the house becomes necessary.
