The Wisconsin Department of Health Services on Wednesday reported 585 total cases of coronavirus infection, an increase of 128, or 28 percent, since 2 pm on Tuesday.
Public Health Madison and Dane County reported 88 cases, up 16 since Tuesday.
By 7 pm Wednesday, though, the Johns Hopkins University Coronavirus Resource Center reported 621 confirmed cases and seven deaths, up one from the six reported by the Wisconsin DHS.
It is the largest single-day jump since the pandemic first began affecting Wisconsin about two weeks ago.
The state reported just over 10,000 negative tests in total.
One new fatality was reported by DHS Wednesday — an individual in their late 70s from Dane County. Johns Hopkins also reports that an additional fatality in Milwaukee County. One death has been reported in Fond du Lac County, one in Ozaukee County and now four in Milwaukee County.
Up to 20 percent of those who have tested positive have required hospitalization, Bureau of Communicable Diseases Chief Medical Officer Ryan Westergaard said in a media briefing Tuesday. Westergaard also said that as many as 90 percent of the people infected never require medical care and therefore don’t get tested.
“We have hundreds of cases confirmed, but it could potentially be thousands right now,” he said.
On Tuesday, Governor Evers directed the DHS to issue what he’s calling a “Safer at Home” order, which closes non-essential businesses and orders people to stay home whenever possible. The order went into effect at 8 am today.
“No pot-lucks, no playdates, no dinner parties,” Evers said.
DHS Secretary-designee Andrea Palm said it might seem like an overreaction to issue the order — there were only 457 cases in Wisconsin.
“Our state benefits from those who have come before us,” such as Italy and Wuhan, China. Palm said public health experts’ models predict as many as 22,000 cases and 1,500 deaths in Wisconsin by April 8 if no measures are taken.
