|Wow, you must be higher than a kite tonight!|
First the science:
Covid update: Latest study looks at how COVID-19 is spread ...
Many respiratory viruses can spread via contact and droplet transmission but increasing epidemiological data have shown that viral aerosol is an essential transmission route of COVID-19 and influenza virus due to its ability to spread rapidly and high infectiousness.
Now apply the science to your propaganda:
Cloth masks do not stop smoke particles, still effective against COVID-19
By BEATRICE DUPUYSeptember 15, 2020
CLAIM: CDC warns that non-N95 masks will do nothing to protect you from wildfire smoke because “they do not catch small particles.” Smoke particles are larger than those of SARS-CoV-2, the virus that causes COVID-19, so masks do not work.
AP’S ASSESSMENT: False. Cloth and surgical masks are designed to prevent the spread of the coronavirus by catching respiratory droplets coming from the person wearing the mask. Respiratory droplets are larger than smoke particles.
Fact: Cloth masks and N95 masks are completely different form each other but AP decides to cleverly confuse the issue and conflate the two so the typical 2nd grade level reader that actually believes the AP propagandistas will believe cloth mask are the same as medical grade N95 masks and swallow this rather large lie. It worked for Rat!
THE FACTS: Social media posts are misrepresenting information by the U.S. Centers for Disease Control and Prevention regarding masks and wildfires to claim that masks do not work.
The CDC recently updated its guidance on wildfires to include information about the coronavirus. On the page titled “Wildfire Smoke and COVID-19,” the agency said that cloth masks would not protect anyone from wildfire smoke.
“Cloth masks that are used to slow the spread of COVID-19 by blocking respiratory droplets offer little protection against wildfire smoke. They do not catch small, harmful particles in smoke that can harm your health,” the agency said.
Online posts are using that information to say that if smoke particles are larger than those of the coronavirus, then how could masks be effective in stopping COVID-19.
“Mask won’t prevent smoke inhalation. But keep thinking they are protecting you from a virus,” one post on Facebook said. The posts were shared across Facebook and Twitter with one post on Twitter receiving more than 8,000 likes.
Such posts miss the point of wearing cloth or surgical masks.
“If the wearer has a respiratory droplet that has a virus, facial coverings keep that droplet from going out into the area around them which is why facial coverings are recommended when people are not social distancing,” Dr. Albert Rizzo, chief medical officer for the American Lung Association, said. “It’s never been designed to protect the person wearing the mask.”
Except that science now knows that Covid, like flu, is primarily spread not with droplets but by aerosol sized particles when the infected spreaders is in an enclosed space and heavily shedding small particles over extended period of time to those in the enclosed area with him/her.
N95 masks are engineered to protect against inhaling very small particles about .3 microns in size and larger, making them effective against smoke and virus particles, said Dr. Jonathan Parsons, a pulmonologist at The Ohio State University Wexner Medical Center.
Wildfire particles range anywhere from 2.5 microns and smaller. A coronavirus particle is about .125 microns in size.
“Cloth masks and surgical masks are not designed to protect you against particles that small so the smoke goes through,” Parsons said. “Respiratory droplets are much larger than the harmful materials in the wildfire smoke.”
And if droplets were the primarily means of spread, this would all make sense, but we now know this isn't true. That's why Covid spreads because infected people are readily identifiable.
Parsons recommends wearing cloth and surgical masks to curb the spread of COVID-19 in wildfire areas even if they do not protect against smoke particles.
This is part of The Associated Press’ ongoing effort to fact-check misinformation that is shared widely online, including work with Facebook to identify and reduce the circulation of false stories on the platform.

|This is from a 2004 CDC slide presentation to the National Academy of Science urging the participants to engage in fomenting fear in the public so they'll take useless flu vaccines.|
