Coronavirus Disease (COVID-19): Face Masks Sep 15, 2022


Why do people wear masks?

Masks are a key measure to reduce transmission and save lives.


Wearing a well-fitting mask should be part of an overall "Go All Out!" Approaches include maintaining physical distancing, avoiding crowded, closed, and close-contact environments, ensuring good ventilation in indoor spaces, cleaning hands regularly, and covering sneezes and coughs with a flexed elbow tissue.


Depending on the type, masks can be used to protect healthy people or prevent further transmission, or both.



What masks should the public wear?

WHO recommends three types of masks to the public:


 Reusable non-medical masks that meet ASTM F3502 standard or CEN working protocol 17553, or non-medical masks that meet WHO essential parameters;

 Disposable medical masks complying with medical mask standards EN 14683 Type I, ASTM F2100 Level 1, YY/T 0969, YY 0469 (or equivalent standards);

Other types of fitted non-medical masks, including homemade multi-layer masks, may be accepted when other options are not available.

Disposable medical masks are also recommended for the following groups, who are at higher risk of developing and dying from COVID-19 if infected:


People 60 years old or older.

People of any age with underlying health conditions, including chronic respiratory disease, cardiovascular disease, cancer, obesity, immunocompromised patients and diabetes.



Disposable medical masks are also recommended for:


Anyone feeling unwell, including those with mild symptoms such as muscle aches, mild cough, sore throat or fatigue.

Anyone waiting for a COVID-19 test result or who has recently tested positive.

 Nursing staff should wear respirators or medical masks in any setting providing care for patients with suspected or confirmed COVID-19, including home care, long-term care facilities, and community care settings
