Lower numbers on Sundays may represent less weekend testing
The Michigan Department of Health and Human Services (MDHHS) released the following statement about today’s update of COVID-19 case and death statistics.
Although a reduced number of COVID-19 cases are being reported today (April 12), 645 cases compared to 1,210 reported on April 11, and deaths, 95 compared to 111 on April 11, we cannot say if this represents a true decline in COVID-19 cases and deaths in our state.
Reported case counts may reflect a reduction in the amount of laboratory testing performed over the weekend and holiday. Single day fluctuations in the number of confirmed cases may not be significant, as a number of external factors can affect data reporting.
Although there is a limited amount of data to compare, previous testing reports have illustrated consistent Sunday decreases with some being as high as a 25 percent reduction over the previous day. Sunday, March 22 had a 25 percent drop in reported tests. Sunday, March 29 saw a 3 percent drop in reported tests. Sunday, April 5 saw a 25 percent drop in reported tests.
Please note that these represent the date that the laboratory sent the information, not the date of onset of symptoms for the cases which would precede this date and is collected during the public health response to these referrals.
