TL;DR The Tome of Nuance

IMHO this review muddies the messages and flip flops on key mitigation strategies

When the science and our understanding evolves, it’s important to communicate this clearly and concisely to the public rather than fall back on nuance and shades of gray. Even when this means admitting that previous messaging was incorrect.

Side tweet - Probably could have saved some pages by omitting the giant shades of gray diagram - not a difficult concept

We thought SARS-CoV-2 spread primarily through droplet spray at “close contact”. We were wrong. Close range aerosol inhalation is a key mode that was overlooked. Depending on environmental factors (ie indoors, 3C’s), long range inhalation also not uncommon. #COVIDisAirborne

We know that airborne pathogens spread most commonly at close range, where aerosols are most concentrated. The public knows TB is airborne. This doesn’t lead to panic. It leads to airborne mitigation measures like avoiding 3Cs and wearing respirators when in high risk settings

We thought asymptomatic transmission wouldn’t happen. We were wrong. Asymptomatic spread can and does happen.

We thought universal masking wouldn’t help and may hurt. We were wrong. Masks help through source control and through filtering inhaled aerosols for personal protection. True respiratory PPE should optimize fit, filtration & function (ie respirators - N95s/elastomerics)
