What is the actual likelihood of aerosol transmission?
This is a much-discussed question with huge consequences.
A fantastic new paper has actual data to address the question by monitoring infection in nurses caring for #COVID19 patients.

Background
A huge question with any new pathogen is:
How is it transmitted?
SARS-COV-2 is a respiratory virus and *could* be transmitted by surface contamination, close-range contact via large droplets, & longer distance via smaller aerosol particles.

I wrote detailed thread on this before and will summarize key points again here. https://twitter.com/DiseaseEcology/status/1279664793087963136">https://twitter.com/DiseaseEc...
It matters b/c it determines how we stop transmission. If surface contamination was major mechanism then avoiding touching frequently-touched surfaces and hand-washing/hygiene would be key. This was suspected to be important in March & led to 20+ sec hand-washing campaign.
