First COVID-19 Cases Outside Chicago/Cook County

March 10, 2020

The Illinois Dept. of Public Health (IDPH), Kane County Health Dept. (KCHD), and the McHenry County Dept. of Health (MCDH) this afternoon announced the first Illinois residents outside of Chicago and Cook County to test positive at the IDPH laboratory for coronavirus disease (COVID-19).  The cases include a Kane County woman in her 60s and a McHenry County teen, neither of whom had a history of travel to an affected area and no connection to a known case of COVID-19.  Public health officials are identifying and contacting all close contacts.

"As we anticipated, the number of cases in Illinois is increasing and now includes the first cases outside of Chicago and Cook County," said IDPH Director Dr. Ngozi Ezike.  "The State of Illinois continues to take action to reduce spread of COVID-19 in Illinois and we again want to encourage people to start thinking and preparing now in the event they are not able to go to work, if schools are closed, if public transportation is not available, and how else their lives will be disrupted by this outbreak." 

Currently, there are 19 individuals in Illinois who have tested positive for COVID-19.  At least one case acquired the virus in the community, but probably more. IDPH indicates that as it continues to conduct surveillance testing, additional cases will be identified, and we will have a better understanding about the amount of virus circulating in Illinois communities.

In addition to the cases in Kane and McHenry counties, six other new cases include individuals in:

Cook County:

  • 70s - male
  • 60s - female
  • 40s - female
  • 40s – male


  • 40s - male
  • 40s – male

Public health officials are still investigating the travel history of these individuals and any potential contact with a known COVID-19 case.  These most recent cases are in isolation and are doing well.
