* General population:
For best results, people should wear medical masks as they are more effective than cloth masks in preventing infection. These should have three layers to provide good protection against outside particles; and an internal wire across the nose to allow a close fit with no air leaks from the sides.
* Those at high risk of severe Covid-19
Those at high risk of severe disease, such as older people and those with chronic diseases, should wear an N95 or KN95 mask when they are outside or near other people. These masks use multiple layers of synthetic material to provide high levels of protection against outside particles.
* When are people required to wear a mask?
To ensure the health and safety of the population and reduce the spread of Covid-19, the wearing of masks is mandatory in all closed and open public settings. The only exceptions are for children under six years old (although it is safe for children above two years of age to wear a mask) and people performing sports and exercise in open spaces.
