There is very little evidence that face masks will reduce the risk of infection. Masks need to be worn correctly, changed frequently, removed properly and disposed of safely in order to be effective. Therefore, we are not recommending routine use of face masks.  Masks can be useful to prevent the spread of the virus if you are infected. If you have symptoms of a respiratory tract infection and it is essential for you to attend hospital, please wear a mask, or ask for one when you arrive.
