The latest COVID-19 activity level report from the Department of Health Services shows that nine counties in the state have faster per-capita disease spreads in the past two weeks than Milwaukee County. Included among those are the county’s western and northwestern neighbors Waukesha and Washington counties.

Milwaukee’s other two bordering counties, Ozaukee and Racine, also have per-capita case levels above the state average of 182.7 cases per 100,000 residents over the past 14 days.

Milwaukee’s rate fell for the second straight week, as did the rates in Racine and Ozaukeee counties, but Waukesha and Washington counties saw their spreads accelerate. The state per-capita total fell from 194.

Waukesha’s total grew from 280.5 to 290.2 and Washington’s total grew from 273.6 to 278.8.

Milwaukee’s total fell from 278.1 to 252.1, Ozaukee’s fell from 259.2 to 238.7 and Racine’s fell from 286.8 to 205.9.

Marinette County has the highest per-capita total in the state, 422.6 or more than 4 out of every 100 residents, but because of its population the actual total is only 173.

DHS reported 740 new cases on Thursday from 9,871 tests, a positive case rate of 7.50 percent. It’s the first time the state has reported less than 10,000 consecutive tests for a string of five days since May 26th, the day before the state reported 10,000 tests in a 24-hour period for the first time.

The seven- and 14-day rate positive case rates stand at 7.96 and 7.37 percent, the latter at its highest point since early May.

A total of 68,233 Wisconsin residents have tested positive for the disease since the outbreak began, with 5,027 in the past week and 10,454 in the past 14 days. DHS reports that 87 percent of individuals with a confirmed case have “recovered,” as defined by a documented abatement of symptoms or a diagnosis over 30 days ago. A total of 63,126 tests have been processed in the past seven days

The death toll from the disease grew to 1,067, an increase of eight in the past 24 hours. The state has averaged 6.93 deaths per day over the past 30 days and 6.49 per day over the past 100 days.

According to DHS data, 2,387.1 out of every 100,000 Milwaukee County residents have tested positive for COVID-19 (up from 2,363.8) since the outbreak began. Racine County has 1,925.3 cases per 100,000 residents (up from 1,916.6). Brown County, which is anchored by Green Bay, has 1,802.3 cases per 100,000 residents (up from 1,792.2).

Iron (1,714.8), Kenosha (1,688.9), Walworth (1,500.8), Trempealeau (1,321.4), Marinette (1,307.4), Waukesha (1,269.3), Dodge (1,118.8), Waupaca (1,094.4), Lafayette (1,063.6) and Washington (1,008.7) are the only other counties with more than 1,000 cases per 100,000 residents.

The statewide average of cases per 100,000 residents rose to 1,180.8 (up from 1,168 yesterday). Wisconsin has recorded a per-capita rate of 182.7 per 100,000 in the past two weeks according to the DHS activity level report released Wednesday.

  1. Dan Wilson says:

    I wish there was a simple metric the media could adopt that illustrates the up or down trend. Maybe the seven-day average expanded to a two-week average, or a 30-day average of new cases. I find the current batch of numbers bewildering. I just want to know what progress we are making.

  2. Jeramey Jannene says:

    There is regrettably not such a figure, but there are a few that I would suggest keeping an eye on.

    1. The positive case rate – it should trend downward if cases are slowing (particularly if testing is expanding). It is currently trending up substantially as testing contracts (a likely indicator that more people should be tested).
    2. Total cases – a surge in total cases, including what was seen in much of July, will lead to more hospitalizations and deaths in the future (what is being seen now)
    3. New hospitalizations and active hospitalizations – these are both lagging indicators but indicators none the less. Daily new hospitalizations, on a rolling 30-day-average, are near an all-time high set a week or two ago. Active hospitalizations are not at an all-time high (but are elevated compared to a month ago), the why is the interesting question. Have strategies gotten better? Are cases less severe because of limited exposure (masks, shorter contact, etc, etc)? Or because it’s younger people being admitted? No easy answer there.
    4. Deaths – Another lagging indicator. The death rate is highly variable based on age, so Wisconsin’s per case death rate has dropped as the majority of cases are in young people. But the total number of cases has spiked, leading the daily death total to climb substantially from where it was a month ago.
