Public Health Staff from either your local health department or the IDPH Surge Center are reaching out to individuals who have COVID-19 and their close contacts. Through these calls, they ensure that anyone who has COVID-19, as well as their close contacts, has the necessary support to isolate or quarantine safely. Please do your part; answer the call and provide our staff with all the information needed to help slow the spread of COVID-19 in our communities.



As part of our case investigations, public health staff will work to contact everyone who has COVID-19 along with their close contacts. By participating and answering our questions, you will protect the lives of your family, friends, and community members by helping to slow the spread of COVID-19.


Any information you share with public health workers is CONFIDENTIAL. This means that your personal and medical information will be kept private.

Public health staff will NEVER ask for:

  • Money

  • Debit/Credit Card or Bank Account Information

  • Social Security Numbers (SSN)

  • Immigration Status


First, public health staff will call anyone who has COVID-19 and will always provide residents with their name and 

312-777-1999 or 309-582-3759 as the call back number. 

The number that will appear on your phone from the IDPH Surge Center is 312-777-1999 and/or IL COVID HELP. Any of the following numbers will be MCHD staff: 582-3759, 582-3761, 582- 3762, 574-3264, 574-3265, 574-3266,

If you miss a phone call from any of the above numbers, please call the same number back to ensure you are speaking to the person who originally called you.

Occasionally we experience a glitch in the system. If you haven't received a call from public health staff, please call your local health department.

During the call, public health staff will ask you to confirm information about yourself, information about your close contacts, and they will ensure that you have the necessary resources needed during isolation. We will encourage you to notify your contacts about your illness. 

Once your interview is completed, contact tracers will reach out to your close contacts and notify them that they have been exposed to someone with COVID-19. Again, all your information is confidential, the only information your contacts will receive is that last date of exposure to the positive case. The necessary information for quarantine will be provided to them, they will be advised to stay at home, monitor their symptoms and be in touch with their healthcare provider. Staff will ensure they have the necessary support and resources.
