Change in Cases

Commentary

Last Updated: October 02, 2020

Utah has left a phase where the COVID-19 data seemed to be improving and the state was entering a better position. Now the state is seeing an even greater outbreak than when the crisis started and even since the second surge in cases starting around June. Active cases are increasing at a breakneck rate, hospitalization is increasing, and the ratio of positive to total cases is rising to new heights, suggesting an undercount in cases statewide. Utah county is a major contributor to the rise (and also has more lax restrictions than the more populous Salt Lake county while also having a large population), and the rise also comes as schools resume classes.

Details

"Recent" means difference between the total of the most recent day and the day prior. The positive to total ratio is the ratio between recent positives and recent total tests, which is the sum of recent positive and recent negative results.

With the exception of the graph for total active cases, all charts are of daily changes, or ratios of daily changes. Red dotted lines present on some charts mean levels of interest, such as whether daily change in active cases is above or below zero—an increase or decrease in active cases—or whether the ratio of recent positive to recent total tests is above or below 0.05. The blue dashed line is a trend line estimated via Loess regression, and the shaded region surrounding the line is a 95% confidence region for the location of the trend line; in particular, note that the confidence region for the trend line is not a forecast for the location of future series values.
