Incorrect mask usage

Incorrect mask usage refers to the wearing of a face mask in a manner that is not sufficient to protect against the spread of disease. In certain settings, such as healthcare, masks may be necessary to protect workers and/or patients from the spread of disease. During a pandemic, health experts may recommend the public wear masks in some settings. Wearing masks incorrectly may compromise the benefit they are intended to provide and possibly increase the risk of disease transmission.
Public education campaigns can be used to help instruct the public on how to wear a mask correctly.
Incorrect ways of wearing masks
Depending on the type of mask and the reasons for which it is worn, there are various ways in which a mask can be worn incorrectly.
Not fully covering face
Masks to protect against the wearer catching disease and spreading it to others are supposed to cover both the mouth and nose. Wearing it in a manner that does not fully cover both loses this benefit. Covering the nose is especially important in COVID-19 protection because the virus is transmitted primarily through the nose.
Wrong type of mask
Different types of masks are intended for different purposes. Masks may be necessary either to protect the wearer, protect others from diseases the wearer could possibly unknowingly be carrying, or protect from foreign objects or allergens.
Experts say cloth and surgical masks may not fully protect against the COVID-19 Omicron variant
Worn out mask
Disposable medical grade masks are intended for limited or one-time use. Those who reuse them or use them longer for the period of time for which they are intended risk infecting themselves. Masks also may lose their protective value.
