The actual reported COVID-19 on May 27 was 5,334, an increase of 68 deaths from the day prior. Of those 68 deaths 14 were identified by reviewing death certificates and the COVID database and then tacked onto the daily total. Furthermore, of those 68 deaths Southeastern Michigan accounted for 48 of them.

Chart 7 (a 5-day rolling average) portrays how the total number of COVID deaths in Southeastern Michigan continues to increase at a much slower rate, with Detroit reporting the highest cumulative number of deaths at 1,329 on May 25. Wayne County had the second highest total at 1,044 on May 25.

Chart 8 portrays the total number of COVID deaths per 100,000 people on May 27, and all the per capita rates in Southeastern Michigan remained the same for at least the third day in a row, showing that the number of new deaths are in fact stabilizing. The cumulative total of COVID deaths per 100,000 people in Detroit was 197 (representing 1,347 deaths). In Wayne County there were 97 COVID deaths per 100,000 people (1,059 total deaths-no increase from the day prior).

Chart 9, the five day rolling average of deaths,  shows the number of new statewide deaths increased by 8 from the day prior. On May 25 the State reported 35 COVID deaths. Chart 10 shows how the number of deaths in Southeastern Michigan have experienced minimal increases in the last day or two. Detroit reported 10 daily COVID deaths, which was a small increase from the day prior. This was also the highest number of new daily deaths reported in the region. On May 25, of the 35 new deaths reported 18 were reported out of Southeastern Michigan. These numbers are based on 5-day rolling averages.

On May 27 Detroit reported a fatality rate of 12.4 percent, which was a small increase from the day prior but a number the City has reported several times over the last week. The fatality rate in Macomb County again hit 12 percent, and the State continued to report a fatality rate of 9.6 percent for 9 days in a row.

One reason we may be seeing such high fatality rates in Michigan is due to the low testing rates. When only having-presumably-a lower of number confirmed COVID cases than is actually likely due to the limited availability of tests, the fatality rate appears higher because the base comparison is smaller than it might be.

The number of new cases COVID cases reported in Michigan did nearly doubled on May 27 after a lull over the holiday weekend. However, 75 percent of those new cases came out of areas other than Southeastern Michigan. As the holiday weekend gets farther away we will see have to see if the daily COVID numbers continue to increase or decline, as we all hope.
