Tuesday, September 22, coronavirus data by Michigan county: Western UP has 6 counties in red or orange

The coronavirus outbreaks at Michigan Tech University, along with the aftermath of Labor Day weekend and the fallout from a coronavirus outbreak in neighboring Wisconsin, have six western Upper Peninsula counties at risk. high levels of COVID-19 transmission.

Three UP counties — Houghton, Iron and Menominee — are now all coded red, based on a metric developed by the Harvard Global Health Initiative to assess coronavirus risk levels.

The Harvard Institute metric uses a seven-day average of new cases per 100,000 population. The latest assessment is based on data from September 15-21.

Three other counties — Delta, Dickinson and Ontonagon — are in the orange zone, signaling heightened concern.

The six counties have recorded a total of 270 new coronavirus cases over the past week, including 97 in Houghton, home of Michigan Tech.

“We’re about two weeks away from Labor Day weekend, so we’re seeing the effects of gatherings and socializing over the holiday weekend,” said Michael Snyder, who heads the health department for Delta and Menominee counties. “And now, of course, the schools are back, so there’s more interaction there, and we’ve continued to increase testing in our long-term care facilities.”

Another factor for western UP is its proximity to Wisconsin, which currently has one of the highest coronavirus transmission rates in the country, with a 17% positivity rate on diagnostic tests from coronavirus.

On the Lower Peninsula, Ingham County is still coded red, the result of ongoing outbreaks among Michigan State University students. Code orange corresponds to Cass, Benzie, Iosco and Ottawa counties. The latter is struggling with outbreaks at Grand Valley State University.

In Ingham and Ottawa – where public health officials have imposed quarantines on students – the numbers are starting to drop.

Ingham no longer averages more than 100 cases a day; in Monday’s report, which covered a two-day period, the county had 85 new cases.

Meanwhile, Ottawa had 270 cases last week, down from 373 the previous week.

At the other end of the spectrum, seven counties are in the green zone as of Tuesday morning, according to the Harvard Institute metric. These counties currently have minimal coronavirus transmission.

Five counties — Alcona, Algiers, Keweenaw, Lake and Luce — reported no new cases last week.

The other “green counties” are Mason and Ogemaw.

The map below is shaded by the average number of new cases per day per 100,000 population. The arrows indicate whether the total number of cases over the past seven days (September 15-21) has increased or decreased compared to the previous seven days (September 8-14).

Latest news on coronavirus testing

Five Michigan counties have a positive rate of at least 5% in reported coronavirus tests in the last 14 days ending September 20. The state averages more than 28,000 tests a day.

Iosco County had the highest 14-day average at 7.6%, followed by Cass (6.1%), Macomb (5.5%), Ingham (5.4%) and Benzie (5. 4%).

Note: The number of positive tests does not correspond to confirmed cases, because the same patient can be tested more than once.

The World Health Organization says schools can safely reopen if fewer than 5% of coronavirus tests in the past two weeks are positive.

Below are online databases that allow readers to search county-level data for each of the past 20 days.

Cases per day it was reported to the state

The first is a graph showing new cases reported to the state each day for the past 20 days. This is based on when a confirmed coronavirus test is reported to the state, which means the patient first fell ill a few days prior.

You can call up a graph for any county and you can hover your cursor over a bar to see the date and number of cases. (As of September 1, the state stopped reporting numbers on Sundays, so the numbers for September 7, 14, and 21 cover two days.)

(In a few cases, a county reported a negative (decreasing) number of new daily cases, following retroactive reclassification by the Michigan Department of Health and Human Services. In these cases, we subtracted cases of the previous date and put 0 in the reported date.

The following table below shows new cases in the past 20 days based on symptom onset. In this chart, numbers for the most recent days are incomplete due to the lag between people getting sick and getting a confirmed coronavirus test result, which can take up to a week or more.

More localized maps

Below are two maps created by the EpiBayes research group at the University of Michigan Department of Epidemiology, which has access to subcounty data collected by the Michigan Department of Health and Human Services.

The interactive maps break the state down into 10 kilometer hexagons to provide a more localized view of where coronavirus cases are occurring. You can click here to access the research project website.

The first map looks at confirmed and probable coronavirus cases over the past week. You can click on a hexagon to see the underlying data.

You can use the triangle button at the top right of the map to switch to the second map, which shows the total number of confirmed coronavirus cases and deaths since the start of the pandemic.

Last daily report

On Monday, which includes numbers for Monday and Sunday, the state reported 1,563 new cases of the novel coronavirus and 12 deaths.

The state’s seven-day average is now 684 new cases per day, down from an average of 737 a week ago. The seven-day average of deaths is nine deaths per day, which is unchanged from September 14.

Along with washing your hands regularly and not touching your face, authorities recommend practicing social distancing, assuming anyone can carry the virus.

Health officials say you should stay at least 6 feet away from others and work from home, if possible.

Use disinfectant wipes or disinfectant spray cleaners on frequently touched surfaces in your home (doorknobs, faucets, countertops) and carry hand sanitizer with you when you go to places like stores.

Michigan Governor Gretchen Whitmer also issued executive orders requiring people to wear face coverings over their mouths and noses in crowded indoor and outdoor public spaces. See an explanation of what this means here.
