Starbucks Cafe’s Covid Outbreak Spared Employees Who Wore Masks – Bloomberg
This was pretty striking: ‘A person sitting under an air conditioner infected 27 others with coronavirus at a Starbucks cafe in South Korea, but none of the employees, who were wearing masks, got the virus.’ Another great case writeup from South Korea (Via Andrew Flood)

Proactive screening for COVID-19 is individually costly
Thread from Professor Carl T. Bergstrom:
[…] proactive testing carries individual costs: those associated with purchasing the tests, time costs of taking them, and serious social and economic costs if one tests positive and has to self-isolate for upward of a week. So, we have an intervention that is costly to you but beneficial to others. We need to think about what the incentives are for people to (1) decide to take a daily test before the results are known and (2) follow through appropriately if a test comes up positive.
