How to know when you should double-mask

When it comes to preventing the spread of COVID-19, we know that more distance between people is better than less, smaller crowds are safer than larger, and outdoor activities are less risky than indoor ones.To get more news about famous nonmedical mask stock, you can visit official website.

We also know that a wide variety of face masks work to protect both the wearer and those around them. So are two better than one? Dr. Anthony Fauci has hypothesized that the answer is yes, as have experts on virus transmission.

And now, there's evidence they're right. According to a study out of the Centers for Disease Control and Prevention February 10, if everyone double-masked, we could reduce COVID-19 exposure by 96.4%, Insider's Hilary Brueck reported.

But that doesn't mean wearing two masks is right for everyone, since a well-fitting one can be nearly as effective. Here's how to figure out what works best for you. In general, face masks work by blocking the large respiratory droplets that spread the virus when people sneeze,or cough. They can also serve as a barrier against smaller aerosols, a less common but still possible way the virus transmits.

The CDC study showed that while a single surgical mask on an infected person blocks about 42% of infectious particles from reaching a healthy person and a cloth mask blocks more than 44%, wearing a cloth mask over a surgical one blocked 92.5% of cough particles.When both parties (or dummies, in the case of the study) are double-masking in this way, the protection 96.4%, Brueck reported. That seems to be because the surgical mask filters out virus particles well, while the cloth mask can improve the fit.

Stephen Morse, a professor of epidemiology at the Columbia University Medical Center, told Insider he's found this strategy is more comfortable than a single mask, as it helps prevent the inner lining from sticking to his face when he breathes. If two masks is irritating to you, don't force it. "The real limit is likely to be comfort. Can you breathe through the combo?" Morse asked. "Otherwise, you might not fit it closely enough to your face, and then it could be less protection than one good, well-fitting mask."

A well-fitting mask should seal around the nose and mouth, preventing droplets from escaping through any gaps.The CDC study found you can make a single surgical mask fit better by knotting the ends and tucking the fabric so it better hugs the face. That strategy, it found, is almost as effective as double-masking.

One mask may be sufficient in certain situations, too. Biking solo through a sparse neighborhood, for instance, requires less protection than standing in a crowded grocery store line.
