I really enjoyed the long, thoughtful discussion I had with @zeynep @TheAtlantic on this complex topichttps://twitter.com/zeynep/status/1288837333752709122 …
Hah, true! I tried, as we chatted, to focus on the fairly overwhelming consensus on how we can stack ventilation as a layer of mitigation, despite the remaining uncertainty on exact mechanisms. I suspect there will be fascinating research for years into the rest!

Such a challenge: to communicate all the unknowns, and yet the need for practical steps especially if they are easy/cheap, but also no scaremongering.
