I spent an inordinate amount of time this year subtweeting articles, commenting on policy and discussing corona with folks on Twitter. Because I read studies and listened to weeks worth of podcast content on the topic in three languages (e.g. Das Coronavirus Update and This Week in Virology) I’d like to believe I have at least a somewhat informed take on the issue. I’ll try to summarise some of that here.
I wanted to get an order of magnitude sense of the utility of non-medical masks. Specifically their usefulness against floating droplets at a reasonable distance, and not from someone coughing loudly; those people can easily be avoided. In addition I focus on short term exposure. In other words, should I worry when waiting in an orderly line to order my take out frappuccino?
