A face mask cannot possibly stop a coronavirus.
Established science published by the Journal of the American Medical Association proves that facemasks should NOT be worn by healthy individuals
A study published in the New England Journal of Medicine on April 1, 2020 states:
“wearing a mask outside health care facilities offers little, if any, protection from infection.”New England Journal of Medicine April 1, 2020 issue, Study entitled Universal Masking in Hospitals in the Covid-19 Era link: https://www.nejm.org/doi/full/10.1056/NEJMp2006372
Then two months later the doctors who reported their study suddenly backtrack and write a letter to the editor published on June 3, 2020 at NEJM.org.
“the intent of our article was to push for more masking, not less. It is apparent that many people with SARS-CoV-2 infection are asymptomatic or presymptomatic yet highly contagious and that these people account for a substantial fraction of all transmissions.”New England Journal of Medicine June 3, 2020 Letter to the Editor. link: https://www.nejm.org/doi/full/10.1056/NEJMc2020836
Why is their retraction contrary to the known science published by the National Institutes of Health that asymptomatic individuals have ZERO chance of spreading the disease?
A study published by the National Institutes of Health on their government website link: https://pubmed.ncbi.nlm.nih.gov/32513410/ says that there is ZERO chance of spreading the disease — out of the 455 individuals (hospital staff, family members, patients) in close contact for several days with positive tested carriers.
Size of the Coronavirus is too small to be filtered
According to a study published in the New England Journal of Medicine https://www.nejm.org/doi/10.1056/NEJMoa2001017
“Electron micrographs of negative-stained 2019-nCoV particles were generally spherical with some pleomorphism. Diameter varied from about 60 to 140 nm. Virus particles had quite distinctive spikes, about 9 to 12 nm, and gave virions the appearance of a solar corona.”
A nanometer is one-thousandths of a micrometer (mm, also called micron). A virus diameter of 60 to 140 nanometers is a diameter of 0.060 to 0.140 micrometer.
Filter capability of N95 surgical mask
A N95 Surgical Mask is a mask manufactured to meet the NIOSH part 84 regulation N95. This government regulation requires the mask to filter out 95% of particles that are larger than 0.3 micrometers (0.300 microns). It will let through 5% of particles greater than 0.300 microns.
In other words, N95 mask will NOT filter out five side-by-side coronavirus, Nor 5% of larger particles that it is not required to filter out. Plus whatever gets in around the mask — and this is for government regulated surgical masks, not for cloth masks.
Even Surgical Masks have never been effective
Here is the proof:
Face masks are dangerous
Here is an article from Sign of The Times:
Cloth masks are just for virtue signaling politicians.
