Masks! How They Keep Us Safe

What are Masks?

Masks are a piece of cloth or paper that people wear to cover their noses and mouths. Wuh Lien-tuh was a Chinese doctor that invented masks in the early 1900’s. Wuh Lien-tuh invented layered masks because there was a virus outbreak. We are using masks right now!

How Do Masks Work?

Masks work by preventing aerosols from exiting out mouth or nose. Aerosols are tiny droplets that come out of your mouth and nose when you cough, sneeze, or even breathe! These aerosols can be carrying bad viruses and bacteria that can make other people sick. The mask does two things: it prevents the aerosols from leaving your mouth, and two, it prevents the aerosols from other people from going inside of your mouth and nose. That is why it is VERY IMPORTANT that you wear your mask on your nose and your mouth.
