"However, there is currently no evidence that wearing a mask (whether medical or other types) by healthy persons in the wider community setting, including universal community masking, can prevent them from infection with respiratory viruses, including COVID-19." World Health Organization, April 6, 2020 Interim Guidance
"Between 2004 and 2016 at least a dozen research or review articles have been published on the inadequacies of face masks. 5,6,11,17,19,20,21,25,26,27,28,31 All agree that the poor facial fit and limited filtration characteristics of face masks make them unable to prevent the wearer inhaling airborne particles. In their well-referenced 2011 article on respiratory protection for healthcare workers, Drs. Harriman and Brosseau conclude that, “facemasks will not protect against the inhalation of aerosols.” 11 https://www.oralhealthgroup.com/features/face-masks-dont-work-revealing-review/
Masks: Are There Benefits or Just a Comfort Prop? Let the Facts Speakhttps://www.collective-evolution.com/2020/05/21/masks-are-there-benefits-or-just-a-comfort-prop-let-the-facts-speak/
"Dr. Russell Blaylock warns that not only do face masks fail to protect the healthy from getting sick, but they also create serious health risks to the wearer. The bottom line is that if you are not sick, you should not wear a face mask."
"The researchers found that the mask reduced the blood oxygen levels (pa02)significantly. The longer the duration of wearing the mask, the greater the fall in blood oxygen levels. The importance of these findings is that a drop in oxygen levels (hypoxia) is associated with an impairment in immunity. Studies have shown that hypoxia can inhibit the type of main immune cells used to fight viral infections called the CD4+ T-lymphocyte. This occurs because the hypoxia increases the level of a compound called hypoxia inducible actor-1 (HIF-1), which inhibits T-lymphocytes and stimulates a powerful immune inhibitor cell called the Tregs. This sets the stage for contracting any infection, including COVID-19 and making the consequences of that infection much graver. In essence, your mask may very well put you at an increased risk of infections and if so, having a much worse outcome.5,6,7"https://www.technocracy.news/blaylock-face-masks-pose-serious-risks-to-the-healthy/
