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, with the numbers in Wayne County now reaching above those in Detroit. On July 27, Wayne County’s numbers reached 12,589, which was above Detroit’s reported number of COVID cases at 12,574. Charts 3 and 3.1 show the new daily COVID case numbers and reflect a spike on July 22, followed by decreases in the number of new daily COVID numbers. On July 27, which is reflective of 5-day rolling average data, Wayne County reported the highest number of new cases at 20.

The daily data highlighted in these posts is from Michigan.gov/coronavirus, where data is updated daily at 3 p.m. Historical data were supplied from covidtracking.com, 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.
