The public health departments of Illinois and Cook County announced that another person has become infected with COVID-19 on Saturday.
Health officials said the person's test results will need to be confirmed by the Centers for Disease Control and Prevention, but the patient is currently in isolation.
"Public health officials are working to identify and actively monitor individuals who were in contact with the patient in an effort to reduce the risk of additional transmission," the departments said in a statement. "The state of Illinois will request CDC deploy a team to Illinois to support these efforts."

Meanwhile, a Palatine family is worried about their daughter who's currently quarantined while studying abroad in Italy due to the novel coronavirus outbreak.
Jena Spahic has been studying abroad in Italy for a month. But the Marquette University sophomore said she's barely been able to leave her Airbnb as concerns over COVID-19 continue to grow.
"It seemed kind of like an apocalypse when I went out. It was really eerie," Spahic said. "I was kind of really scared. I didn't know if people were going to be wearing masks, if there was going to be any people out, if there was going to be food at the grocery store."
Classes at the university canceled last week after Italian officials announced hundreds of confirmed cases of novel coronavirus.
"So far, I'm not studying anything. I haven't even been in the classes yet. Our classes were supposed to start last week, Spahic said.
Spahic's family is taking action to get their daughter back to Chicago.
"She is packing right now. As soon as we can get the flight, she is coming home," said Dee Spahic, Jena's mother.
The family said Marquette University did not have students' health and safety as a top priority.
"We contacted the school and the school said you can bring her home, it is up to you, but she will lose a full semester," Dee Spahic said.
Marquette University sent a letter to students studying abroad in Italy on Saturday, recommending that they return to the U.S.
"Due to recent changes in the virus outbreak in Italy, Marquette University is strongly recommending that you return to the U.S.," the statement read.
But will students lose credit for this semester?
"They said it is more than a month into the semester and they cannot catch up, so they will lose a semester," Dee Spahic said.
What about a refund for the thousands of dollars now wasted on canceled classes?
"I'm basically taking a semester off involuntarily," Jena Spahic said.
"They should have got the students out, back on a plane, back here and back in school," said Rick Spahic, Jena's father. "That is what they have to do."
On Saturday, the Trump administration elevated travel warnings to regions of Italy and South Korea, urging Americans not to travel to those areas.
