COVID-19 in Central Kansas Counties

Dates of interest:

• The City of Wichita (in Sedgwick County) adopted a face mask ordinance on July 3.
• Harvey County’s mask ordinance took effect July 15.
• The Harvey County Fair happened July 30 - August 3 with little observation of COVID-19-safe practices.
• KDHE Sec. Norman says it can take 1 to 2 incubation periods (so 2-4 weeks) for the effects of masks or other enhanced protocols to be visible in the numbers. Because this chart uses a 7-day simple moving average, the effect is further delayed.
• The Harvey County data had a downward correction in number of cases on January 22, reducing by over 100. This explains the unnaturally low (and even negative) numbers you see in the 14 days after that.

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.

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.

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.

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.
