With Indiana's recent surge in coronavirus metrics, Chicago residents could see the state on the city's travel order by Tuesday, according to Chicago Department of Public Health Commissioner Dr. Allison Arwady.
"Indiana very well may be added to Chicago's travel order next week," Arwady said last week.
The state has already crossed the average of 15 cases per 100,000 residents, sitting at 15.8 as of last week, Arwady said, but the city chose to keep it off the list.
"We made a decision not to add it this week for a few reasons," Arwady said.
Among those reasons were the fact that the state had recently changed the way it reports its coronavirus data and that state colleges have marked a large spike in cases.
"If we don't see improvement across the state then we will add them next week," Arwady said last week.
As of Monday, more than 100,000 individuals in Indiana tested positive for coronavirus since the pandemic began, according to state health officials, adding 596 new cases and four additional deaths.
The rolling seven-day positivity rate for all tests maintained steady at 5.4 % on Monday, and among unique individuals tested, that figure also stayed consistent at 7.4%, health officials said.
Chicago's travel order was updated once again last Tuesday adding three states to its quarantine list, including some that were recently removed.
The states added to the list include Hawaii, Nebraska and North Carolina.
Both North Carolina and Nebraska had previously been removed from the quarantine list.
The emergency order now requires anyone visiting or returning to the city from one of 22 locations to self-quarantine for 14 days.
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 currently included are: Alabama, Arkansas, California, Florida, Georgia, Hawaii, Idaho, Iowa, Kansas, Louisiana, Mississippi, Missouri, Nebraska, Nevada, North Carolina, North Dakota, Oklahoma, South Carolina, South Dakota, Tennessee and Texas, as well as Puerto Rico.
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 has released 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.
