This is prompted by our Commissioner of Health saying last week that masks definitely work. Well let’s see. Here is a chart showing the date the mandate was enacted. At that time the state first said it would take two weeks to work, but later amended that to four weeks. So we labeled four weeks later, see the big drop? Me either. See the huge spike while mask wearing was 90% plus. And then there is the date the mandate finally expired. Kind of ironic how the mask mandate didn’t work to reduce cases until the mandate was ended, or is that paradoxical? You will note that at no time during the mandate were cases ever lower than before the mandate. And as I constantly said, what really matters is mask wearing. Throughout this period Minnesota had one of the highest mask-wearing rates in the nation, most of the time over 90%. Yeah those masks worked great, as virus collection devices. Thanks to Dave Dixon for putting the chart together.
