Masks stopping Covid is like Stopping a mosquito with a chain-link fence

• Mask mandates never supported by evidence
• Viral PPE includes negative pressure rooms, flow hoods, suits etc
• Don't stop droplet (flu), how could they stop aerosols (CV19)>
• Pore size in cloth, surgical masks were too big to stop CV19
• Denmark and Bangladesh RCTs showed no impact on absolute risk reduction
