Over 900 Mayo Clinic staff in Midwest have contracted COVID-19
Here's a link to yesterday's article. https://www.yahoo.com/gma/over-900-mayo-clinic-staff-031548190.html
First, I hope everyone does well.
Key quote: "Most of the exposure — about 93% — happened in the community, not at work, Williams said."
Second, this suggests to me that no matter how disciplined and thorough your organization is and how knowledgeable the staff is, everyone is at increased risk if the community baseline level is high.
For me personally, what I use to track my direct local risk is my county health department website with particular attention on positive tests and hospitalization rate trends. In Washington State, with the acceleration of these, we just went back to increased closures and restrictions a day ago. With the highest community positive test rate right now, my wife and I are being much more selective in going out than we were even in March/April.
(I only spend 5-10 minutes a day thinking through our Covid Daily Risk strategy, but it is a very important 5-10 minutes.)
