The negligent, outdated beliefs of medicine's management class (everywhere; from the UK inquiry here) contrasted with well-understood science from 👉1934👈. If you got sick after being told that COVID falls to the ground within 3 feet and N95/FFP2/FFP3 respirators aren't needed, 👉it was their fault.👈
The focus on handwashing over ventilation  12.32. As 2020 progressed, it was increasingly understood that airborne transmission of Covid-19 was a substantial risk and, by 23 July 2020, SAGE had endorsed the importance of good ventilation.ON AIR-BORNE INFECTION.*  STUDY II. DROPLETS AND DROPLET NUCLEI.  BY  W. F. WELLS, t  (Beceived for publication June 14, 1934.)  The infective range of droplets expelled from the nose or mouth depends primarily upon the time interval spent in the atmosphere. The unresisted falling time from mouth to ground can be readily shown by Newton's Law to be less than a second. Air resistance becomes a negligible factor in determining the time of fall of droplets larger than a tenth millimeter through the height of a man. As droplets decrease in diameter the volume and weight, or gravitational pull, decrease more rapidly than the surface area which determines the resistance to fall through air. Particles smaller than a tenth millimeter diameter soon reach a velocity which remains constant. This fact is expressed by Stokes' Law % which says that the velocity is proportional to the surface area of the droplet or to the square of its diameter.droplets would reach the ground in less than ten seconds (table 1). Whether droplets falling two meters obey Stokes' law or Newton's law, therefore, the time they spend in the air would be small, and their radius of spread would be limited to a few feet. Infection caused by such droplets would therefore appear to be limited both in time and space to the immediate vicinity of the source.  TABLE 1.  Settling of water droplets in saturated air.  Diameter of droplet Falling velocity Time in seconds of Millimeters Centimeters per second falling two meters > 1.0 981 X time in seconds .6 .1 30. 6. .01 .3 600. = 10 minutes .001 .003 60,000. = 16.6 hours  It would be incorrect to conclude merely from this, however, that air receiving infected droplets cannot convey such infection long distances. To do so would be to neglect a most important characteristic of liquid droplets, namely their tendency to evaporate. Evaporation causes the volume of water droplets to change, and this change becomes more rapid as the droplet decreases in size. Careful determination of the rate of evaporation has proved that at constant temperature and humidity the rate of change of surface is constant. The life of droplets in unsaturated air is therefore proportional to the square of their diameter. It becomes quite short for small droplets, in fact much shorter than their time of fall if they settled without evaporation. Approximate evaporation times for droplets of different sizes are tabulated below. We find, therefore, that minute droplets settle slowly and evapoTABLE 2.  Evaporation time of water droplets in unsaturated air at 18° C*  Diameter of droplet Evaporation time Millimeters Seconds 2 660. 1 165. .5 41. .2 6.6 .1 1.7 .05 4  * Computed from data given in chapt. 15, "Evaporation of Droplets." Smoke: A Study of Aerial Disperse Systems; R. Whytlaw-Gray and H. S. Patterson, page 176 Edward Arnold & Co., London, 1932.A chart from Wells (1934) showing that particles smaller than 100 microns shrink (via evaporation) to a size small enough to remain airborne indefinitely before they have time to fall to the ground.

Associated text reads:

"This is an important difference since it produces a complete change in state of small droplets in comparison with large drops. On chart 1 the curves of evaporation time and falling time (to fall two meters in saturated air) are seen to be almost similar in shape but opposite in direction. The point of intersection gives the size of droplets which would evaporate and particles which would fall two meters in the same time. Somewhere between .1 and .2 mm. lies the droplet size which identifies droplets of mouth spray that reach the ground within the life of the droplet as against droplets that evaporate and remain in the air as droplet nuclei with attached infection."
