The WHO provides an easy, step-by-step guide on properly wearing a face mask.
Before using your face mask, sanitize your hands using alcohol or soap. You also need to wash them before and after taking your mask off.
Inspect the face mask for any holes or tears on the surface.
Wear your mask as needed. It must cover your chin, mouth, and nose. For surgical masks, make sure to have the white side on the inside.
Pinch the wire on the nose if there’s a nose strap.
When done using, take it off by the straps and place it in a clean breathable bag.
