Nonpharmaceutical Measures for Pandemic Influenza in Nonhealthcare Settings—Personal Protective and Environmental Measures

Limited Evidence of Effectiveness

Individuals may feel as though wearing face masks provide a sense of security that allows them to disregard other important hygienic practices such as washing their hands or physical distancing.

False Sense of Security

Government officials and some health officials advise against the use of face masks citing concerns regarding the limited quantities of face masks in circulations, meant for health workers in hospitals, nursing homes, and other congregate facilities as well as at-risk individuals.

Limited Quantities

Many sources point out that members of the public may not wear face masks in its intended usage, such as leaving the nose uncovered, taking off the mask whenever it feels uncomfortable, or reusing disposable masks.
