The US Centers for Disease Control and Prevention has been conducting a scientific review about the public health benefits of masks, and will soon make an updated recommendation, a senior CDC official told CNN.
The reviews are happening even though the CDC has already published guidance on its website.
A senior official with knowledge of the review said science is being studied as to whether masks are not only “good for source control — and keeping you from giving it to others — but we’re also seeing if masks are going to protect you from getting [Covid-19] yourself.”
“We know it’s a good thing to wear a mask to protect others. We are studying if it is also potentially going to keep you safe,” the official added.
The CDC website has two separate pages of guidance on face coverings. One recommends people wear masks when they leave their home. The other recommends people wear a mask if they cannot properly social distance.
An official at the agency says recommendations from a final scientific review by its incident management “will happen soon.”
