The Centers for Disease Control (CDC) published today that wearing a cloth mask over a surgical mask substantially improves protection against the coronavirus infection beyond wearing just a single cloth mask. Fitting a cloth mask over a surgical mask could reduce the wearer's exposure to aerosols by more than 90%, the CDC has stated.
A recent CDC study found that an unknotted surgical mask blocked 42% of particles from a simulated cough, researchers say, while a cloth mask alone blocked 44.3% of particles. When combined with the cloth mask over the surgical mask, 92.5% of cough particles were blocked. The data in this report underscore the finding that good fit can increase overall mask efficiency.
The CDC recommends that people wear masks in public settings, at events and gatherings, and anywhere they will be around other people.
A mandatory mask-wearing requirement is in effect in our state of Colorado. We continue to require wearing a mask for employees and patrons at PCCLD. We are working now to order PCCLD cloth masks that can be worn over a surgical or other mask to provide additional protection against transmission of the coronavirus.
