Tests have shown face masks have no detectable effect against transmission of viral infections. The CDC reported that 85% percent of respondents who tested positive for Coronavirus reported having "always" or "often" warn a face covering 14 days before the onset of their illness. A paper published in the Annals of Internal Medicine determined surgical and cotton face masks are ineffective at blocking SARS-CoV-2 particles created during a hard cough. A study of 44 mask brands found mean penetration of 35% by Covid aerosol gas. Backward unfiltered airflow was found to be strong with all masks compared to not masking. In respiration, the relevant aerosol is the suspension of bacterial or viral particles in inhaled or exhaled breath.
Honeywell N95 respirators are made with a 0.3 micron filter. Coronaviruses are approximately 0.125 microns in diameter. An analysis of cloth masks used during the 1918 pandemic examines the failure of masks to impede or stop flu transmission at that time, and concluded that the number of layers of fabric required to prevent pathogen penetration would have required a suffocating number of layers. Democrat leaders are openly saying they are using the Covid pandemic to advance their "progressive" agenda. Marxists/Democrats continue to fight to keep the U.S. economy shut down to prevent President Trumps re-election.
Dr. Kulldorff of Harvard, Dr. Gukpta of Oxford and Dr. Bhattacharya of Stanford, recommend the most compassionate approach is to allow those who are at minimal risk of death to live their lives normally to build up immunity to the virus through natural infection, while better protecting those who are at highest risk. It is essentially the approach followed in Sweden, the country that has most successfully dealt with the virus.
