March 17, 2020: Doremalen et al, NEJM (experimental) showed SARS-CoV-2 remains viable in aerosols for hours, supporting airborne spread.
March 19, 2020: Zou et al, NEJM (virology observational) showed that SARS-CoV-2 reaches extremely high viral loads in the nose and throat at or before symptom onset which explained the ease of presymptomatic transmission and why COVID-19 spreads so efficiently through shared air.
March 26, 2020: Bourouiba et al, JAMA (mechanistic) highlighted that SARS-CoV-2 can spread much farther than current social distancing guidelines suggest (far past the social distance recommendation of 6 ft, up to ~23-27 ft), especially indoors
