The number of new COVID-19 cases in Wisconsin in the past 24 hours increased by over 33 percent Tuesday, but the number of tests administered fell by 20 percent.

In total 3,933 processed tests resulted in 198 new cases as 5.03 percent of tests came back positive. That’s below the seven-day average of 6.02 percent and the 14-day average of 6.30 percent, but substantially ahead of yesterday’s report of 2.90 percent. Public health officials are looking for that number to steadily trend downward, even as testing increases.

But testing didn’t increase over the past 24 hours. The 3,933 tests processed were below the seven-day average of 5,394.71 and the 14-day average of 4,899.21.

According to the Department of Health Services, 12,885 Wisconsin residents have now tested positive for the disease, an increase of 198 from yesterday’s total. DHS data shows that 57 percent of those people have recovered, as determined by the case either being first diagnosed over 30 days ago or the state having a record of resolved symptoms. Since the outbreak started, 2,110 people have required hospitalization as a result of complications with the disease.

The death toll from the virus has reached 467, with eight newly-confirmed deaths in the past 24 hours. Four percent of people with confirmed cases have died from the disease.

Milwaukee County is the site of 5,076 of the 12,885 confirmed cases and 260 of the 467 deaths according to state data.

Both Brown and Racine counties continue to have greater per capita outbreaks than Milwaukee.

Brown County, which is anchored by Green Bay, has 815.3 cases per 100,000 residents (up from 809.1 yesterday). Racine County has 543 cases per 100,000 residents (up from 529.2). Milwaukee County has 532 cases per 100,000 residents (up from 524.5).

Kenosha (514.5), Walworth (278.6), Rock (270.8) and Kewaunee (152.3) are the only other counties with more than 150 cases per 100,000 residents.

The statewide average of cases per 100,000 residents has risen to 223 (up from 219.6).

There are currently 954 ventilators and 470 intensive care unit (ICU) beds available across the state according to the Wisconsin Hospital Association. Since the data became publicly available on April 10th, WHA has reported an average of 928 ventilators and 426 ICU beds as available.
