      We now have more data supporting the airborne nature of sars-2 than we have for measles. Looking forward to hearing from ID colleagues about why measles cases can now be managed with droplet precautions.

      I think one block to progress here has been lack of understand that what's called droplet precautions, of course, also dampen aerosol transmission (which concentrate near the emitting person) especially in well-ventilated places like US/Canada hospitals, and masks are universal.+

      There is also the fact of HCwer and nosocomial transmission at rates we would never have contemplated in our most pessimistic moments pre pandemic . These require transparent, meticulous and open minded assessment.

      Don’t forget about the study at Brigham Woman’s where the technican was wearing droplet precautions and still got infected in a short exposure.https://twitter.com/abraarkaran/status/1359253780097818625?s=21 …

      1/ The major #covid19 outbreak from @BrighamWomens where I work is now published in @AnnalsofIM — definitely worth a read. Phenomenally detailed work here from many smart people. The index patient tested negative twice, but soon became positive after. https://www.acpjournals.org/doi/full/10.7326/M20-7567 … pic.twitter.com/bolQwEfB7v

      Of course. I think a key point here is that "droplet precautions" aren't useless. They do a lot against aerosols as well (and a lot of good lab/mechanistic studies on why) especially if they are universal, but there is part of the risk curve outside it as well.

          👍🏻 Specifically 1. distance helps avoid the higher concentration aerosols + the direct ballistic hit of the larger droplets pre evaporation. 2. source control with FRSM helps both- droplets >aerosol but very good 3. FRSM excellent for mucosal protection, not inhaled

          When diverge in terms of mitigation- 1. Close + no source mask + no FFP3 for extended periods of time. Hand wash and clean away ( rightly so) but still aerosol risk 2. >2m in closed space poor ventilation - hands and clean away but still aerosols to breath

          yes, but worth mentioning that the majority of Covid19 infection is from asymptomatic & pre-symptomatic patients.. who by definition are not coughing & sneezing.. so not producing much droplets
