COVID Update: Michigan Cases Reach 104,395

Michigan reported 685 new COVID cases on Sept. 3, 2020, bringing the total number of cases Michigan reported to 104,395. In Chart 1 we show that the State total for the number of COVID cases on Sept. 1 was 103,159–a five-day rolling average. The five-day rolling average for the total number of COVID cases (Chart 1) reflects a smoother curve and adjusts for fluctuations in testing and/or the quality of reporting or failure to report.

Chart 2 shows that, based on the five-day rolling averages, the growth of new COVID cases in Southeastern Michigan continues to increase. However, the chart also shows that the growth of COVID cases in Detroit has begun to stagnate compared to the growth of cases in Wayne, Oakland and Macomb counties. On Sept. 1, Wayne County reported the highest number of cases in the region at 15,909. Oakland County reported 14,611 cases and Macomb County reported 12,484. Detroit reported 13,696 COVID cases on Sept. 1.

In addition to having the highest number of total COVID cases Wayne County in the region, Charts 3 and 3.1 (which is just a closer look at the data) shows that it also had the highest number of daily cases on Sept. 1. Wayne County reported 33 new cases on Sept. 1. Oakland County reported 27 new daily cases, Macomb County reported 28 and Detroit reported 10 new cases, according to the five-day rolling averages.

The daily data highlighted in these posts is from, where data is updated daily at 3 p.m. Historical data were supplied from, which republishes COVID data from the State. Additionally, the case totals do not reflect the number of people who have recovered, just those who have been infected. In early June the State changed how it reports its data on the website, making data more accurate in the long-term but more complicated to track as well. The State regularly updates older data and as we continue to publish regular updates on COVID the State’s changes to past data many not always be reflected in our posts. The data published in new posts is accurate for the day we received it on though.

In Chart 4, the five-day rolling average for the number of deaths in Michigan, shows the number of deaths in the State of Michigan reached 6,495 on Sept. 1. The actual cumulative COVID-19 deaths on Sept. 3 was 6,519, an increase of 10 deaths from the prior day.  However, of those 10 deaths, 9 were added to the daily total after death certificates were compared to the COVID database.

Chart 7 (a 5-day rolling average) further hones in on how majority the number of COVID related deaths has significantly flattened out in Southeastern Michigan. On Sept. 1, the City of Detroit reported 1,510 deaths. Wayne County had the second highest total at 1,241 deaths on Sept. 1.

Charts 6 and Chart 6.1 shows how on Sept. 1 Macomb and Oakland counties each reported 2 new deaths and Wayne County reported 1 death.
