“Face masks should be used only by individuals who have symptoms of respiratory infection such as coughing, sneezing, or, in some cases, fever. Face masks should also be worn by health care workers, by individuals who are taking care of or are in close contact with people who have respiratory infections, or otherwise as directed by a doctor. Face masks should not be worn by healthy individuals to protect themselves from acquiring respiratory infection because there is no evidence to suggest that face masks worn by healthy individuals are effective in preventing people from becoming ill.”
Preventing Infection Acquisition
Hand hygiene is one of the most important ways to prevent acquiring and spreading respiratory infections. Wash your hands often. Try not to touch your nose, eyes, or mouth prior to washing your hands. Avoid close contact with others who are sick. Clean household surfaces and objects with wipes or cleaning spray when available. If you become ill, stay home to avoid making other people sick.
