The CDC now recommends that you wear a mask with the best fit, protection, and comfort for you.
Layered prevention strategies such as staying up to date on your vaccines and wearing a mask can help prevent severe illness or death.
The CDC has implemented a new tool to help us decide what prevention steps to take based on the latest data. Use the tool below to find your county and the recommended prevention measures you can take.
Choosing a mask
It is important that your mask fits well and that you wear it correctly and consistently. Your mask should completely cover your nose and mouth, fit snugly against the sides of your face and not have gaps, and have a nose wire to prevent air from leaking out of the top of the mask. Multilayer cloth masks are preferred over single-layer cloth masks. Be sure to wash your cloth masks after each wear.
Transmission of the virus can occur when an infected person expels respiratory droplets and a non-infected person breathes these in through their nose and into the lungs, or touches a surface with the droplets on them and then touches their mouth or nose. Respiratory droplets are called aerosols and are a type of particle in the air. Larger sizes can carry the COVID-19 virus through the air.
Stanford Medicine, University of Colorado, Arizona State University, and others have found that the cloth face covering, depending on the material, can protect the user from about 50% of particles in the air like those from coughs and sneezes. Also, because these face coverings cover the mouth and nose they stop the source of the aerosols produced by sick, pre-symptomatic, and asymptomatic people.
