The state shows no signs of being out of the woods on one of the key factors the Department of Health Services is using to gauge the effectiveness of its fight against the COVID-19’s spread.
For the third day in a row, Wisconsin reported over 3,000 tests were processed and over 10 percent came back positive.
The increased testing totals are a positive sign, besting the April average of 1,917, but they’re still below the reported testing capacity of 11,147 tests at 50 labs.
And while testing is trending in a positive direction, the percentage of those tests that are coming back positive is trending up, which is not what public health officials want to see.
“The trend is the important thing,” said Dr. Ryan Westergaard, Chief Medical Officer of the DHS Bureau of Communicable Diseases, during a briefing Wednesday. “We want to see a sustained move in the right direction. We have been a little flat going between nine and 11 percent.”
The state averaged a positive test rate of 9.57 percent in April. But over the past 14 days that figure jumped to 9.87 percent and 9.66 percent in the past week. For the past three days it’s been 11.3 percent.
DHS reported Saturday that 3,350 people were tested in the past 24 hours, 346 of which came back positive (10.33 percent).
The death toll from the virus has reached 334, with seven new deaths in the past 24 hours. DHS reports that 191 of the deaths have occurred in Milwaukee County. The county’s residents represent 3,147 of the 7,660 confirmed cases according to state data. Testing access has increased in Milwaukee with community health centers and Walgreens launching drive-thru testing.
The gap between the percentage of residents with a confirmed case inMilwaukee and Brown counties to grow. Brown County, which is anchored by Green Bay, now has 489.6 cases per 100,000 residents (up from 452.3 yesterday). Milwaukee County has 329.8 cases per 100,000 residents (up from 319). On April 16th, Brown County had only 53.5 cases per 100,000 residents while Milwaukee had 204. Brown County has now reported five deaths.
Kenosha County has the third-highest rate at 309.5 cases per 100,000 residents. Racine (208.8), Walworth (177.6), Rock (150.2), Sauk (100.6) and Ozaukee (100.8) are the only other counties with more than 100 cases per 100,000 residents, the latter two crossing the threshold for the first time in the last 24 hours. The statewide average has risen to 132.6 (up from 126.6).
The cumulative hospitalization rate for those with confirmed cases stands at 21 percent (1,591 people) over the length of the outbreak after peaking at 30 percent, but the state does not have hospitalization data in 21 percent of cases (1,631 cases).
There are currently 969 ventilators and 418 intensive care unit 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 921 ventilators and 446.25 intensive care unit beds as available.
