I just completed an interview with the Minnesota Department of Health. At this point, they appear to be saying 10 days from first symptoms, assuming you are generally trending better? I'm not entirely sure, since I was pretty focused on my own situation. After some discussion, we agreed to go with the more conservative approach of 10 days from when I took the test, rather than 10 days from first symptoms, in part because my symptoms are fairly amorphous. So, they think I am ok to actually interact with another human come Friday. Which is great, really.
