New @CDCMMWR finds that after Kansas put in place a mask mandate in July 2020 rates of #COVID19 decreased in counties with a mask requirement & increased in counties without one.

Commentary on Twitter
The #COVID19 response focuses on acute illness, but accumulating evidence shows morbidity beyond acute infection, with at least 2 other periods of illness: a rare postacute hyperinflammatory illness, and late inflammatory/viral sequelae https://t.co/mrf8WDxKY4 @jtsylee @CDCgov

Commentaries on Twitter (threads – click for more)
Not perfect, nor confirmatory, but a good enough study to modulate the probability of a large self-efficacy from masks. Study powered to a 50% RRR, correctly concluded that it does not reduce infection by 50%. A negative study is negative only for the effect size it was powered https://t.co/aDPxRoIuqS
