Both WHO (2006) & CDC (2007) admitted that cough etiquette recommendations were made "on the basis of plausible effectiveness rather than controlled studies"
6 years of taking on .@WHO directly on Twitter about droplet dogma
Of pointing out their failure to tell the world that COVID is airborne
After they published this rubbish
I first referenced a freshly published paper w easy to understand, hard to deny, visuals that showed coughs & sneezes produced 'jets' that could travel 8m or more, included a continuum of particle sizes & persisted in the air
This was after spending 2 months trying to convince early Twitter & WHO influencers that Covid was airborne & to pls help warn the world
