The state update 10/21/20 includes data up through 10/20/20 and so I updated the positivity graphs. The moving average continues to move up.
I isolated the ND counties associated with metropolitan areas in the state to investigate positivity there.
The state updates the positivity data daily at around 11, so to the extent my schedule allows I will update in the afternoon. Here are the updated graphs for data released 10-20-2020.
With ND daily COVID-19 positivity rates fluctuating so much I created a 14-day centered moving average and overlaid it on the daily values to look at trends and smooth out the volatility.
