Airborne transmission is key. There is a high risk of the coronavirus (COVID-19) being spread through the air. This is key. But messaging is not clear.
Several terms are used to describe this. These terms include airborne, droplets and aerosols. But the bottom line is airborne transmission seems to be the main method of spreading the virus. This is key.
This is now part of the guidelines by the Centers for Disease Control and Prevention (CDC).
Here are the key mask messages. Please share them.
Masks Protect the Person Wearing the Mask
Masks help protect us from the virus. This is key.
Masks Protect Others, too
Masks also protect others, too. It can be days before symptoms appear. Yet, you could still spread it. Also, some people carry the virus but never experience symptoms themselves.
Masks Telegraph a Key Health Message
A mask is a health message. Wearing one telegraphs an important health message.
A mask reminds the person wearing it that the virus is serious. It also reminds others of the same message, too. Please set a positive example for others. Wear a mask.
A Face Shield Alone is not enough
A face shield alone will not stop COVID-19. Here is why.
We first published this story on September 2. It is worth repeating.
A simple study shows the limits of a plastic face shield. And they will not protect us from the virus. Nor protect others. It was done at the Florida Atlantic University.
However, wearing a face mask with the face shield does work.
Face shields have some advantages. Experts point out that a face shield will protect the eyes and discourage touching of the face.
Testing is Key
One the key tools to reduce the spread is testing. See our guide on testing.
