Only in the past month have public health authorities in Canada acknowledged that SARS-CoV-2 is primarily spread through the air, after more than a year of prevaricating by ‘Droplet Dogmatics’ in face of the evidence.
“Since March 2020, Ontario [Province of Canada] public health guidelines have stated that droplet precautions are adequate to guard against COVID-19 transmission. According to the province, airborne precautions, such as N95 masks, are needed only by those performing aerosol-generating procedures, such as intubating a patient [in June 2021].” —CBC 2021-06-20
COVID-19 is an airborne disease. Canada’s Chief Public Health Officer only publicly acknowledged airborne transmission this November. But many protocols to control fomite transmission continue, such as plexiglass dividers and surface washing conveyor belts in supermarkets.
In view of overwhelming evidence, our structures — workplaces, schools, eating establishments — still do not change to adapt to the evidence. Peter Drucker is attributed for the saying that ‘Culture eats strategy for breakfast’. [What Drucker really said was, “Culture—no matter how defined—is singularly persistent.”] Or perhaps Robbie Burns said it best when considering what happens to our ‘best laid schemes’.
