How it works

  • COVID-19 spreads mainly among people who are in close contact.
  • All of us have droplets in coughs and sneezes that can carry COVID-19 to others.
  • Coughs spray droplets at least 6 feet. Sneezes travel as far as 27 feet. Droplets also may spread when we talk or raise our voice.
  • These droplets can land on your face or in your mouth, eyes and nose.
  • When you wear a mask, it keeps more of your droplets with you.
  • A mask also adds an extra layer of protection between you and other people’s droplets.
