Health workers in clinical settings. See our guidance for more information on the use of personal protective equipment by health care workers.
Anyone who is feeling unwell, including people with mild symptoms, such as muscle aches, slight cough, sore throat or fatigue.
Anyone awaiting COVID-19 test results or who has tested positive.
People caring for someone who is a suspected or confirmed case of COVID-19 outside of health facilities.
Medical masks are also recommended for the following groups, because they are at a higher risk of becoming seriously ill with COVID-19 and dying:

People aged 60 or over.
People of any age with underlying health conditions, including chronic respiratory disease, cardiovascular disease, cancer, obesity, immunocompromised patients and diabetes mellitus.
Non-medical, fabric masks can be used by the general public under the age of 60 and who do not have underlying health conditions.

 

When should masks be worn by the general public?

In areas where the virus is circulating, masks should be worn when you’re in crowded settings, where you can’t be at least 1 metre from others, and in rooms with poor or unknown ventilation. It’s not always easy to determine the quality of ventilation, which depends on the rate of air change, recirculation and outdoor fresh air. So if you have any doubts, it’s safer to simply wear a mask.

You should always clean your hands before and after using a mask, and before touching it while wearing it.

While wearing a mask, you should still keep physical distance from others as much as possible. Wearing a mask does not mean you can have close contact with people.

For indoor public settings such as busy shopping centres, religious buildings, restaurants, schools and public transport, you should wear a mask if you cannot maintain physical distance from others.

If a visitor comes to your home who is not a member of the household, wear a mask if you cannot maintain a physical distance or the ventilation is poor.

When outside, wear a mask if you cannot maintain physical distance from others. Some examples are busy markets, crowded streets and bus stops.
