Why Wear a Mask
Masks reduce the spread of respiratory droplets when you talk, cough, or sneeze. They help protect others if you are infected but feel well. In crowded indoor spaces, a mask can lower transmission risk.
Types of Masks
Common options include disposable surgical masks, cloth face coverings, and respirators such as N95 masks. Surgical masks block large droplets, while tighter-fitting respirators filter smaller particles. The best mask is one you can wear consistently and comfortably.
How to Wear a Mask Correctly
Wash your hands before putting the mask on. Cover your nose, mouth, and chin with no gaps on the sides. Avoid touching the front of the mask while using it, and replace or wash it when it becomes damp or dirty.
