Michigan has updated its breakdown of the latest COVID data and trends, showing a possible slowed increase in the spread of the virus, a new categorization for some variants and rising hospital metrics.
The new data was posted Thursday morning but represents COVID facts in Michigan as of Tuesday (Sept. 28).
Here are 63 important takeaways:
- Michigan as a whole remains under the category of “high” transmission.
- Cases per million are plateaued or decreasing in most Michigan geographical regions, though trend numbers are being impacted by backfill times, according to state officials.
- The percent of COVID tests coming back positive has held steady from last week, at 8.8%. This is a 9% decline since the recent peak on Sept. 12.
- The case rate rose from 234.4 cases per million people last week to 246.3 cases per million this week.
- Michigan’s case rate has increased for three straight months.
- The percentage of inpatient beds occupied by people with COVID in Michigan has increased to 7.4%.
- The hospitalization rate in Michigan has increased for 10 straight weeks and is up from 7% last week.
- Michigan has the 17th-lowest inpatient bed utilization in the country and the 13th lowest adult ICU bed utilization in the country.
- The state’s death rate is 2.8 per million people, up from 2.3 deaths per million last week.
- Michigan’s death rate has been increasing for eight straight weeks. There were 194 COVID deaths between Sept. 14 and Sept. 20.

- Currently, only the delta variant and its sublineages are considered “variants of concern” in the United States.
- The CDC has introduced a new class of variants, called “variants being monitored.” These are variants that are no longer detected or are circulating at very low levels in the country and don’t pose a significant threat to public health.
- Currently, the alpha, beta, gamma, epsilon, eta, iota, kappa, mu, zeta and B.1.617.3 variants are all classified as “variants being monitored.”
- The World Health Organization currently classifies delta, alpha, beta and gamma as “variants of concern.”
- There have been 10.57 million doses of the COVID-19 vaccine administered in Michigan.
- About 52.25 of eligible Michiganders are fully vaccinated -- 5.21 million people.

- Most doses of the COVID vaccine are currently being administered by pharmacies, local health departments and hospitals.
- 68,235 third doses of the vaccine have been administered since it was recommended for immunocompromised people.
- Trends over time show case and death rates among fully vaccinated residents are much lower than unvaccinated residents.
- Older age groups in Michigan have had higher vaccine coverage and lower case rates during the delta and alpha variant surges.
