(KAIR)--Only five of the 105 counties in Kansas are not placed in the high division when it comes to the number of coronavirus cases identified by state health officials.  That means the majority of the state, including all of the local area. is listed in the high class, meaning 100 coronavirus cases per 100,000.  

The Kansas Department of Health and Environment explains those figures come through what's known as the Weekly Cumulative Index Rate. The state health department calculates the weekly cumulative incidence rate by summing the number of new COVID-19 cases with a symptom onset date for a weeklong period, divided by the population in the county and multiplied by 100,000.  

The dominant High Case class is among four classifications used: Low, Moderate, Substantial, and High.  

The latest Kansas figures reflect the reporting period beginning July 16 and ending July 22.
