This article has been making the rounds. It doesn’t actually answer whether a *substantial* portion of spread happens via aerosols. It says that aerosols likely play a role. This has been a largely consistent assumption.

2/ The only take-away for me from this is that we need better masks. We don't know if aerosols play a significant role. They might. They might not.

If they do, cloth masks are not enough. If they don't, better masks are still better.

3/ In my mind, right now there are 3 pragmatic ways out of this:

1) Substantially increase masking, esp indoors + better masks

2) Consistent avoidance of high-risk, crowded indoor venues. Bars/gyms/indoor dining etc

3) Rollout of rapid diagnostic platforms

4/ Additional critical points:

-cont test/trace/isolate--> harder to depend on this when cases are rising exponentially. Still needs to happen. Digital tracing...

-need diff federal leadership (November...)

-central isolation options away from the home. Period.
