COVID-19 in Central Kansas Counties

Dates of interest:

Note that the higher the population of a county, the more useful the statistical data is for interpreting a trend. Marion County looks bouncy because just one or two people can make a significant difference in the case rate even if it is hard to use to predict a trend.

New COVID-19 Cases: Global Perspective

This graph is similar to the one before, but looks at things on a more global perspective. Again, notice how poorly the USA fares, and how Kansas is even worse.

Updated graph: masks vs. no-mask counties

This graph is a different view of the data KDHE Sec. Dr. Norman presented, updated to the present day (his was updated through August 3). It shows new cases per 100,000 population. Note that the mask counties began with a much higher case rate than the no-mask counties, and after the adoption of masks, significantly narrowed the gap. The mask counties were and are higher due to being more dense and urban.

Changing mask rules have made the mask vs. no-mask county distinction somewhat arbitrary; for instance, neither Harvey nor Saline adopted mask requirements at the beginning, but did so later.

KSDE Metric Graphs

These charts pertain to the school reopening metrics set out by KSDE.

Some of the relevant data is above; additional data is here.

2-week cumulative county incidence rate

COVID-19 Test Positivity Rates - Local & Global Perspective

This graph shows what percentage of all COVID-19 tests are coming back positive. The WHO and CDC recommend no more than 5% (the “recommended maximum” line on the chart). Values above that indicate insufficient testing in the population and greater likelihood of undetected cases.

Note how many countries are doing better than the recommended, and, as of August 2020, how poorly both Kansas and the United States are doing.

You will observe an unusual peak in the Kansas data beginning July 27 and extending for 14 days. There was an apparent data correction that occurred at KDHE on July 27, and so it reflects in the 14-day average from that date. This is apparent in the KDHE screenshots from July 26 and July 27 that reflect a reduction of approximately 1000 negative cases and a corresponding reduction in the total test result count, leading to a very high calculated positivity rate on that one day. Since we are using a 14-day window, this effect persists for 14 days.

COVID-19 Test Positivity Rates - Harvey County, KS

This graph shows the percentage of all COVID-19 tests coming back positive, smoothed across a 2-week window as used in the KSDE metrics.

The source data for this comes from the Kansas Department of Health and Environment (KDHE) and from the Harvey County Health Dept. Neither makes an automated download available, so these may be updated less frequently than the rest of the data on this site because a human must manually update the numbers.

About these charts

These charts are generated by the covid19ks program using the covid19db database aggregation, both by John Goerzen.

The charts identified “NYT” use data from The New York Times, based on reports from state and local health agencies. It uses the aggregation at COVID-19 derived dataset for the data.

Charts identified “COVID Tracking” use data from the COVID Tracking Project at The Atlantic.

Charts identified OWID use data from Our World in Data.

Charts identified JHU use the JHU CSSE COVID-19 Data from Johns Hopkins University.
