Data Points to Keep in Mind
The Calhoun County Joint Operations Center is monitoring key data to understand the spread of the virus in our community. Two helpful data points are, the percent of positive cases, and cases per day per million. State and local leaders monitor these in addition to other data to determine phased reopening, as well as regional status.
A reliable place to see these updated data points is the state's MI Safe Start Dashboard, which can be found at
. Calhoun County is within the Kalamazoo Region, and on this dashboard users can narrow their search by region and even county. As of today, Wednesday, July 29, Calhoun County's positive test rate is 2.0% and our cases per million per day is 19.1. What does this mean?
Positive test rate:
When testing levels are high, a low positive test rate is evidence of declining spread. States across the nation are experiencing a range of positive test rates, and Michigan's overall on this day is 3.4% Health officials have cited 5% or higher as the threshold for concern, including moving regions of the state to different phases of reopening. Local schools have also decided to use this as a gauge for the state of the virus in our community.
Cases per million:
This number provides a baseline understanding of the transmission of the virus in our community. Low levels of new cases suggest limited continued transmission. The state's cases per million is approximately 36.7 per day, which is do
wn from earlier in July.
These are two important data points that provide Calhoun County, as well as Michigan and the nation, a framework for understanding the spread of the virus and benchmarks for when to ramp up our response. The Calhoun County Unified Command Team monitors these numbers for Calhoun daily.
The Health Department also is following confirmed cases, probable cases (people with symptoms who are awaiting test results), and contacts. The change in contacts over the last few months is the most significant. In the beginning, during the statewide shutdown, a positive case might have one or two close contacts, likely from their household. Today, a positive case comes with 10 to 13 close contacts.
"People are spending more time in groups, with more people," said Calhoun County Health Officer Eric Pessell. "We still have community spread. If you find yourself in a group, and someone tests positive for COVID-19, you might find yourself in quarantine for 14 days."
