They were talking about toilet flush aerosol. Singing, talking and heavy breathing (smalllll droplets) are common. Note: many ppl think these are aerosols so just wanted to add this so no one gets the wrong idea.pic.twitter.com/kCQylt4jZq

Of course these droplets would be blocked by a face shield or mask. This is important because community PPE policy will be driven by understanding of risk. We need to focus on source control with face shields and masks
Has there been any research done to show whether a low dose infection is more likely to result in an asymptomatic case?
In animal models but would be unethical in humans at the moment, so it’s unclear
i agree; its not like the virus has "settled on the landscape";
But if you sit in a restaurant for 1 1/2 hours in that aerosol it’s going to be a problem?
Restaurant example from China was droplets spread by an air conditioner but indoors for hours no matter where is risky. Open doors and windows and stay outside if you can. If sick person wears a mask or face shield it could have prevented the outbreak - harder to do when eating
Excellent. I do note one other factor here, not a major one, is that smaller size aerosols do have a generalized characteristic of deeper penetration into the lower lung.
In a preschool classroom where no other students/teacher wear mask/shield, how much protection my child will have if she wears a shield herself? Thank you!
Well, it certainly makes sense that there must be a minimally infectious for this. This applies to all infectious diseases. But how much it is for this one is not known. So, I find the headline of the @nytimes article too speculative. What if it is very low?
Wouldn’t we see higher household attack rates than 10-15% if this was a low infectious dose airborne transmission pathogen?
