CDC Guidance on Masks
February 18, 2021
In the midst of the vaccination rollout, I want to be sure that you have not missed the important new guidance from the CDC about masks.
The CDC conducted research and found that when 2 people are both wearing tightly fitting masks, or doubling up on masks, exposure to aerosols that transmit virus was reduced by 95%.
For example, the CDC recommends wearing a surgical mask (those are the light blue ones that you can readily purchase from a variety of retail vendors, not the N95 type) with a fabric mask on top of that, both adjusted to fit tightly.
Please review this CDC guidance carefully and consider how you can increase your level of protection by wearing a more powerful mask combination.
The CDC research is good news because it means that we can stamp out this virus by
- Increasing our mask protection
- Continuing to safely distance
- Getting vaccinated
P.S. you probably know that I have a personal passion for mask protections. I was one of the first elected officials in the U.S. to propose a mask requirement, and we got it done. Governor Hogan even thanked Montgomery County specifically when he announced a statewide mandate shortly afterwards.
