CDC updates advisory on wearing of masks
From Fox News:
The Centers for Disease Control and Prevention (CDC) on Tuesday updated its guidance on coronavirus-related face masks to include protection for the wearer, too.
The update takes the federal health agency’s previous stance further, which held that wearing a face mask can lower virus spread to others.
The CDC said early research supports community masking to lower virus spread, particularly when it’s estimated that more than half of transmissions stem from asymptomatic people. The agency also explained the filtration power of masks, writing: “Studies demonstrate that cloth mask materials can also reduce wearers’ exposure to infectious droplets through filtration, including filtration of fine droplets and particles less than 10 microns.”
