There is more and more evidence to support that facial masks do not do anything. They do not protect against this virus.
This video explains it:
Here’s another link to support this:
This link provides several scientific articles to support this claim.
“In Epidemics 2017, a meta-analysis concluded that masks had a non-significant protective effect. In the Annuals of Internal Medicine, April 2020, “neither surgical nor cotton masks effectively filtered SARS-CoV-2 during coughs by affected people.”
Here’s another very interesting article:
“COMMENTARY: Masks-for-all for COVID-19 not based on sound data”
Lisa M. Brosseau, ScD, and Margaret Sietsma, Ph.D. wrote a commentary, using 52 professional references, where they state the following:
Sweeping mask recommendations—as many have proposed—will not reduce SARS-CoV-2 transmission, as evidenced by the widespread practice of wearing such masks in Hubei province, China, before and during its mass COVID-19 transmission experience earlier this year. Our review of relevant studies indicates that cloth masks will be ineffective at preventing SARS-CoV-2 transmission, whether worn as source control or as PPE [Personal Protective Equipment].
Overall, the body of research on mask efficacy in real-world settings is small and scattershot. And because SARS-CoV-2 was completely unknown to humanity just five (extremely long) months ago, there is no data on the efficacy of any type of mask-wearing in any setting (healthcare or home) for this virus.
In sum, given the paucity of information about their performance as source control in real-world settings, along with the extremely low efficiency of cloth masks as filters and their poor fit, there is no evidence to support their use by the public or healthcare workers to control the emission of particles from the wearer.
The following article looks at the size of viral particles and if facial masks are effective
“Covid-19 Face Mask Protection – What Leaders Fail to Understand”
“For many fabric materials including shirt, sheet, towel, and handkerchief, the effectiveness factor decreased with decreasing particle size from 4800 to 410 nm, indicating a further decrease in the respiratory protection for virus-containing particles <410 nm.
“nm” stands for nanometre, which is one-billionth
of a meter or a fraction of an inch equaling 0.00000004 (four one hundred
millionths) of an inch. In other words, to equal an inch, something this small
would have to be placed end to end four hundred million times.
410 nanometres, then, equals 0.0000164 (one hundred, sixty-four thousandths) of an inch. Something this small would have to be placed end to end one hundred and sixty-four thousand times to equal an inch.
The size of a single coronavirus is 125 nanometers, four times smaller than the stated limit in the previous quote. This means that the size of a coronavirus is a fraction of an inch equaling 0.00000496 (496 millionths) of an inch, which means that 496 million coronaviruses stacked end to end would equal one inch. Even the tiniest grains of sand stacked 496 million times end-to-end would stretch over fifteen miles. (I encourage readers to look up the size of a virus, the size of a sand grain, and do this calculation for yourselves.)”
Finally, I have met countless of people suffering while wearing a mask, especially people who have underlying lungs issues like asthma or COPD.
To summarize, there is not enough evidence for advocacy that all people must wear masks all the time, and it is proven that cotton masks can do more damage than good.
God bless y’all
