Science: Masks have been proven to be ineffective at preventing the transmission of viruses-- evidenced by the numbers peer-reviewed medical studies, but there are also studies showing negative affects of wearing masks, such as causing Bacterial Pneumonia. An N-95 mask still lets 5% of anything smaller than 3 microns thru all the time. At 10% relative humidity to lets particles up to 8 microns thru. The Wuhan corona virus is 1.25 Nano microns big, that's : 0.00125 microns. That's 2400 times smaller than what an N-95 mask can filter. Yes, you can catch the flu while wearing an N-95 mask, and this variant too. That's the equivalent of putting up chainlink fencing to keep mosquitos out of your yard. And NO... 2 fences won't work either genius. "More to the point, indoor airborne virus concentrations have been shown to exist (in day-care facilities, health centres, and onboard airplanes) PRIMARILY (not secondarily) as aerosol particles of diameters smaller than 2.5 μm, such as in the work of Yang et al. (2011): If his view of the mechanism is correct (ie. "physical loss"), then Shaman's work further necessarily implies that the dryness-driven high transmissibility (large R0) arises from small aerosol particles fluidly suspended in the air; as opposed to larger droplets, which are quickly gravitationally removed from the air. Such small aerosol particles fluidly suspended in air, of biological origin, are of every variety and are everywhere, including down to virion-sizes (Depres, 2012), making wearing a face diaper IRRELEVANT, and if you worked in a lab, you should know that.
