Michigan updated their breakdown the latest COVID data and trends, showing a possible slow increase in the spread of the virus, a new categorization for some variants and increasing hospital measures.

The new data was released Thursday morning, but represents COVID facts in Michigan as of Tuesday (September 28).

Here are 63 takeaways:

COVID indicators

Michigan as a whole remains in the “high” transmission category.
Cases per million are leveling off or declining in most geographic areas of Michigan, although the trend numbers are affected by refill times, state officials say.
The percentage of COVID tests that come back positive remained stable from last week at 8.8%. This is a 9% drop from the recent peak on September 12.
The case rate fell 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 consecutive months.
The percentage of inpatient beds occupied by people with COVID in Michigan has risen to 7.4%.
Michigan has the 17th lowest inpatient bed utilization rate in the country and the 13th lowest adult intensive care bed utilization rate 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 rising for eight straight weeks. There were 194 deaths from COVID between September 14 and September 20.
Michigan’s average seven-day test rate has risen to 3,978.9 tests per million per day.

Regional facts

Michigan’s 83 counties are now classified as being at a “high” transmission level.
Positivity declines in three of Michigan’s eight geographic regions: Detroit, Kalamazoo, and Lansing.
The percentage of positivity in six of the Michigan regions is over 10%.

Delta variant

Of the positive tests available for sequencing in Michigan over the past four weeks, 99% have been identified as the delta variant.
Currently, only the delta variant and its sublines are considered “variants of concern” in the United States.
The CDC has introduced a new class of variants, called “watched variants”. These are variants that are no longer detected or that are circulating at very low levels in the country and do not represent a significant threat to public health.
Currently, alpha, beta, gamma, epsilon, eta, iota, kappa, mu, zeta, and B.1.617.3 variants are all classified as “monitored variants”.
The World Health Organization currently classifies delta, alpha, beta and gamma as “variants of concern.”

Vaccination

There have been 10.57 million doses of the COVID-19 vaccine administered in Michigan.
About 52.25 of eligible Michiganders are fully immunized – 5.21 million people.
83.8% of Michiganders 65 and over are fully vaccinated.
Reports show that the side effects of the third dose are comparable to the side effects of the second dose and are extremely common, officials said.
On average, 4,723 first doses are administered per day.
Most doses of the COVID vaccine are currently 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 that the case and death rates among fully vaccinated residents are much lower than those among unvaccinated residents.
Older groups in Michigan had higher vaccine coverage and lower case rates during delta and alpha variant flares.

Vaccine breakthrough case

Less than 1% of fully vaccinated Michiganders have experienced breakthrough cases of COVID.
There were 30,867 fully vaccinated residents (0.636%) to receive a positive test 14 days or more after the final dose.
A total of 417 fully vaccinated residents died from COVID (0.009%) – 368 in the 65 or older age group.
Only 1,211 fully vaccinated Michiganders (0.025%) were hospitalized with COVID.
Of 500,158 cases of COVID during this testing period, 93.8% were in people who were not fully vaccinated.
Of 14,191 COVID hospitalizations during this testing period, 91.5% were in people who were not fully vaccinated.
Of 5,728 deaths from COVID during this testing period, 92.7% were in people who were not fully vaccinated.

Future projections

Models of the Centers for Disease Control and Prevention project cases of deaths and hospitalizations in Michigan are leveling off, or the increase is slowing.
Ridge regression models predict that cases and deaths will continue to increase in Michigan, although the trends may slow.
CDC data shows child case rates are higher in counties where school districts do not have a mask policy.
Pediatric admissions are on the increase and more than 50% of hospitalized children have not reported any underlying conditions.

Health care

Hospitalizations and intensive care use are increasing.
3.9% of emergency room visits are for COVID diagnoses, up from 3.5% last week.
Michigan hospital admissions have increased for most age groups over the past week.
The hospital census rose 9% after reaching a plateau the week before.
All areas of Michigan have seen an increase in hospitalization trends this week.
The volume of COVID patients in intensive care units has increased 6% since last week after experiencing a 3% drop the week before.
Since hitting a low on July 22, Michigan’s death rate has increased 547% over eight weeks.

Children and young adults

The largest number of cases concerns 10 to 19 year olds. This age group experiences 521 cases per million per day.
The age group representing children 0-9 has seen the strongest growth over the past week, increasing by 10%.
Every day, nearly 370 children under the age of 12 are infected with COVID, 50 more children a day than last week.
The average daily census of pediatric hospitals is around 25.

Age group data

Trends in the case rate for all age groups in Michigan are slowing, with most age groups even declining.
Case rates for all age groups in Michigan are currently between 130 and 415 cases per million people per day, as of September 20.
Case rates are currently highest among those aged 10 to 19, followed in order by those aged 30 to 39, 20 to 29, 40 to 49, and 0 to 9.
The age group with the greatest decline in case rate trends is the 20 to 29 age group, down 9%, or about 35 cases per day.
The case rates for the 10-19, 20-29, 30-39, and 40-49 age groups are all higher than Michigan’s overall case rate.

Data on racial and ethnic groups

Case rates are declining for most races and ethnicities in Michigan.
Michigan officials said the high number of cases with missing data on race / ethnicity, and those multiracial or otherwise is impacting the data on the case rate.
American Indian / Alaska Native have the highest case rates.
In the past 30 days, 22% of race data and 26% of ethnicity data were either missing or reported as unknown.

Outbreaks

The number of active outbreaks in Michigan is up 9% from last week.
Michigan authorities have identified 168 new outbreaks over the past week.

The number of reported outbreaks has increased since last week (218 to 289), including increases in secondary schools (88 to 107), middle / high schools (46 to 68) and preschools / elementary schools (79 to 110).
