news: Double Up

https://www.wired.com/story/how-to-double-mask/

THIS WEEK, THE US Centers for Disease Control and Prevention released findings that double-masking—wearing one face mask on top of the other—can be an effective way to reduce the transmission of the coronavirus that causes Covid-19. It’s a practice experts have been mulling over for a while now, with President Biden’s chief medical adviser Anthony Fauci advocating for double-masking back in January. Now the CDC’s lab tests show that double masks can reduce the likelihood of coronavirus transmission between two people by up to 95 percent if both parties wear them correctly.

Now that masks are (finally!) required on public transportation and federal premises, the CDC has updated its mask guidelines to include advice on double-masking.
