Chicago's travel order was updated once again Tuesday, with Wisconsin falling off the city's quarantine list, but another neighboring state returning.
Wisconsin and Nebraska were both removed from the quarantine list, effective Friday, but Iowa and Kansas have both returned. Arizona and North Carolina were also noted for dropping below the threshold to require a quarantine, but those states will need to stay below the mark for another week in order to be removed from the list.
Chicago Department of Public Health Commissioner Dr. Allison Arwady is expected to deliver an update on the order, along with the city's latest coronavirus data, at noon at City Hall.
As of last week, the list stood at 20 U.S. states and territories. Both Wisconsin and Nebraska were noted for dropping below the threshold required to remain on the list, but they needed a second week of numbers below the mark to be removed from the order.
Wisconsin was officially added to the city's order effective July 31, though the city noted exemptions for some people who work over the border.
Iowa, Kansas and Utah all fell off the quarantine list last Tuesday after multiple weeks of case numbers below the city's threshold, but both Kansas and Iowa marked a return this week.
The city's travel order is evaluated every Tuesday, with any changes taking effect the following Friday.
States are added to the list if they have "a case rate greater than 15 new COVID-19 cases per 100,000 resident population, per day, over a 7-day rolling average." If they fall below that threshold, they could be removed as well.
Chicago's travel order first began on July 6.
The states included are: Alabama, Arkansas, Arizona, California, Florida, Georgia, Idaho, Iowa, Kansas, Louisiana, Mississippi, Missouri, Nevada, North Carolina, North Dakota, Oklahoma, South Carolina, Tennessee and Texas. Puerto Rico was also recently added to the list.
Arwady said travelers entering or returning to Chicago from "states experiencing a surge in new COVID-19 cases" will need to quarantine "for a 14-day period from the time of last contact within the identified state." Essential workers could be exempt from the quarantine requirement, however, as long as their employer certifies their work in writing.
The order is set to remain in effect until further notice.
New York and New Jersey are also asking visitors from several states, including Illinois, to quarantine themselves for two weeks.
Still, outside of Chicago, Illinois Gov. J.B. Pritzker said the state likely won't require residents who travel to and from neighboring states to quarantine for two weeks solely because of that travel.
But Illinois' Department of Public Health on Monday did release a "travel map" indicating which states are a "higher risk" for travelers.
The state's map uses the same criteria as Chicago's travel order for determining the states that are deemed to be an increased risk.
“Travel may increase the chance of becoming infected and spreading COVID-19,” IDPH Director Dr. Ngozi Ezike said in a statement. “To help inform residents where they might be at greater risk of being exposed to COVID-19 when they travel, IDPH has launched a map that clearly shows states and other countries where case rates are elevated. While staying home is the best way to protect yourself and others from COVID-19, we know that it may not be possible to avoid all travel. We encourage people who are traveling, whether for work or otherwise, to check out the map before making plans.”
