  • Wash hands before wearing a facemask.

  • In general, when wearing a surgical facemask, the following should be noted:
      • the facemask should fit snugly over the face;
      • the coloured side of the facemask should face outside;
      • tie all the strings that keep the facemask in place or fix the rubber bands of the facemask round the ears properly;
      • the facemask should fully cover the nose, mouth as well as the chin;
      • the metallic wire part of the facemask should be fixed securely over the bridge of the nose to prevent leakage;
      • under general circumstances, the surgical mask should be changed daily.

  • Put the facemask into a plastic bag and tie it properly before putting it into a rubbish bin. You may dispose a used facemask concealed in a separate bag with the rest of your domestic wastes.
  • Replace the facemask immediately if it is damaged or soiled.

Wearing a facemask is just one of the ways to prevent respiratory tract infections. The most important thing a person should do is to observe good personal hygiene. For example, wash hands frequently with liquid soap, especially after sneezing, coughing or cleaning the nose.
