There are currently a number of anomalies in testing data.
Our testing data provider, The COVID Tracking Project, is in the process of changing how it maps states’ data to the categories we use for our positivity calculations. Additionally, some states have made changes to the data they report. We are currently evaluating how best to adapt to these changes and reviewing our data inputs and calculations to ensure that we can present the most responsible and accurate view of state test positivity data. Placer County Note: Due to rapidly changing conditions, the dashboard will now be updated twice weekly on Tuesdays and Thursdays. Additional daily Placer data is available on the state website.
