For the second time, Chicago on Tuesday added Wisconsin to the list of states on its travel order, meaning travelers returning to the city from there should stay inside their homes for two weeks because of high coronavirus counts.

Health Commissioner Dr. Allison Arwady made the call as part of her weekly update on the states that have earned the designation because of high virus counts. Her move came as Wisconsin’s governor on Tuesday declared “a new public health emergency” because COVID-19 is spiking there.

“Unfortunately, Wisconsin is currently in very poor control when it comes to COVID,” Arwady said. The Badger State now trails only North Dakota and South Dakota in terms of case rates, she said.

Arwady warned last week that if Wisconsin’s case rate didn’t come down below the 15 cases per 100,000 residents threshold Chicago officials use to determine the self-quarantine list, then she would include it soon.

Wisconsin is now at 31 cases per 100,000 residents, she said.

Wisconsin Gov. Tony Evers on Tuesday extended a statewide mask mandate until Nov. 21. The order has been in effect since August, and was scheduled to expire on Monday.

In a series of Tuesday tweets, Evers noted the state’s struggle with COVID-19 and called on residents to help get the disease under control.

“With the start of the school year, we are now facing near-exponential spread of COVID-19. This is driven in part by the unprecedented number of infections among 18-24 year-olds, which have a case rate five times higher than any other age group,” Evers tweeted. “Today I declared a new public health emergency and face covering order effective immediately to address the recent surge in cases among young people. We have to get this virus under control, and we need everyone to do their part, especially students across our state.”

In addition to Wisconsin, Montana, Idaho, Minnesota and Puerto Rico also have been added to Chicago’s quarantine list. Kentucky and Louisiana are removed, Arwady said. The new quarantine requirements take effect Friday.

Mayor Lori Lightfoot’s administration first added Wisconsin to the 14-day quarantine order in late July, only to take it off the list in mid-August when case numbers there dropped.

It’s tough to tell whether the city taking the step makes much difference, since officials are doing little to determine whether people coming to Chicago from these states are following the two-week stay-at-home order. Arwady said the travel list has served mostly to educate Chicagoans to avoid states that are coronavirus hot spots.

“I hope that when people see this news about Wisconsin, they think twice about going to Wisconsin right now,” Arwady said when asked about enforcement. “This is about risk for someone who’s traveling, and then the risk if they bring it back to Chicago.”
