The World Health Organisation (WHO) recommends that masks should be worn 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.
Appropriate use is essential to make wearing masks effective. Even when masks are worn properly, people should still keep physical distance from others as much as possible. Wearing a mask does not mean you can have close contact with people. Medical masks are for single use only.
