COVID-19: The Value of Masks

Medical Perspectives | COVID-19

Masks are important tools in stopping the spread of COVID-19. How do they work? Why should you wear one? What are the different types of masks? And how often should you wash your mask? Watch the video below for answers to these questions and read on for a recap. 

How do cloth masks work? 

Cloth masks are at their best when preventing the wearer of the mask from spreading the virus to other people, either when they are already sick, asymptomatic, or even pre-symptomatic. 

How do N95 masks or surgical masks work? When should they be used? 

N95 masks and surgical masks are best used in a medical setting, when the amount of virus in the environment is quite a bit higher. The intention of these masks is to reduce the transmission of the virus to the person wearing the mask. 

How can wearing a mask be a cultural tool? 

Wearing a mask in your neighborhood, in your workplace, or around your community is a way to show you care about those around you. You are essentially saying, "I care about you. I am member of this community. And my intention is to not give this infection to you, even if I don't know if I've got it."

How often should you wash a mask? 

Cloth masks should be washed every day. It's helpful to have multiple cloth masks available so you can rotate through your supply while others are washing or drying. 

N95 masks or surgical masks are intended to be worn through the course of one day and discarded.
