Fact Check: Debunking misinformation about face masks from buzai232's blog
Since the beginning of the pandemic, there has been a raging — sometimes ill-informed — debate over the effectiveness of face masks as protection against SARS-CoV-2, the virus that causes COVID-19.To get more news about famous medical mask factory outlet, you can visit tnkme.com official website.
Initially, there was limited evidence to support broad masking policies for the general public, and the Centers for Disease Control and Prevention recommended masks only for those infected and medical providers treating them. On April 3, 2020, the CDC reversed course and recommended that everyone wear face coverings in public, citing new data that showed a "significant portion" of people infected with the coronavirus lack symptoms but can spread the virus to others.
Numerous lab studies, for example, show that high-quality, well-fitting masks can partially block exhaled respiratory droplets, which are thought to be the primary way the virus spreads — and may offer some protection to the wearer. In one CDC study, N95 respirators performed the best in preventing the spread of particles from a simulated cough — blocking 99% of the particles — while medical masks blocked 59% and a cloth mask blocked 51%. (See SciCheck’s "The Evolving Science of Face Masks and COVID-19.")
On May 13, the CDC updated its guidance to say "fully vaccinated people no longer need to wear a mask or physically distance in any setting." But two months later, with COVID-19 cases on the rise and the delta variant becoming dominant in the U.S., the CDC changed course again — recommending "fully vaccinated people to wear a mask in public indoor settings in areas of substantial or high transmission."
With each decision, federal health officials have said mask guidelines are based on the "evolution of the science," as Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases, once put it.
The evolving science also has offered an opportunity for those peddling misinformation to distort the facts at every turn.
"It's not healthy for these students to be sitting there all day, 6-year-old kids in kindergarten covered in masks," Florida Gov. Ron DeSantis said in a July 28 speech in Utah, repeating an unsubstantiated health claim that we debunked before.
On Aug. 11, Sen. Rand Paul was kicked off YouTube for a week after making inaccurate claims about the effectiveness of face masks. "Most of the masks you get over the counter don’t work. They don’t prevent infection," Paul said in the video, citing as evidence a Danish study that, as we wrote last year, has been distorted by critics of mask mandates.
In reviewing our work on masking, we have found that false and misleading claims about face masks tend to fall into four categories of misinformation: distortions of science, misrepresentation of government guidance, claims that mask-wearing has been proven to be ineffective and claims that mask-wearing increases your health risk.
There is some overlap of categories. For example, claims that distort scientific research do so to conclude, incorrectly, that masks have proven to be ineffective or even dangerous.
