The U.S. Centers for Disease Control and Prevention (CDC) updated its guidelines for U.S. citizens during the 2020 global global pandemic,media reported. The update includes several key points, such as the CDC’s change of wording on its “How to Wear a Mask” guidance page. They retained the first sentence, which states, “When combined with daily preventive action and social guidance in public places, masks are an additional step to help slow the spread of COVID-19”.
Until Friday, the first message on the page’s list was “Who shouldn’t use masks.” The location of this description may be pushing the reader in the wrong direction. For example, the “wear-free mask” scam and the groups behind it.
The updated guidelines make it clear that the CDC now “recommends people wear ingons in public” is their main message. The guide also expands the “Wear the Mask Correctly” section below. In the correct way to wear the mask, the following points have been added:
“If the mask has an exhalation valve or breathable hole, the CDC does not recommend using a mask or cloth mask for source control.” The CDC says the purpose of wearing masks is to prevent the spread of respiratory droplets to help control the source. However, masks with breathing valves or breathable holes allow air to flow through holes in the material, which can cause respiratory droplets to disperse and reach other areas. This mask does not prevent people wearing masks from spreading COVID-19 to others. Therefore, CDC does not recommend using a mask with an exhalation valve or breathable hole for source control.
