The biggest lie of the Covid-19 apandemic, with the gravest consequence for life and living was a lie told on February 11, 2020. Dr Tedros shared that "Corona is airborne", ready a shorte scribbled note passed to him my Dr Michael Ryan and then told us he mis-spoke.
Of course the main transmission route was aitborne - with infection happen the the simple act of breathing in. Rooms that were ventilated and had air cleaning would lower the risk. Good masks would also lower the risk, but the WHO decided to inform us that it was spread by droplets instead. The world duly enacted two-meter distancing, emthusiastic surface wiping, and hand washing which were not as important as clean air.
