Contact Tracing & Quarantine/Isolation 

IDPH Guidance

Contact Tracing: Illinois Department of Public Health (IDPH) now has a centralized contact tracing system to focus on text notification of all reported positive COVID-19 cases and the investigation of high-risk populations. If you tested positive for COVID-19 at a local test site, you will get a text  with directions from IDPH  to call 312-777-1999 or visit for additional guidance on isolation, close contact notification, and resource availability.

At-Home/Over the Counter COVID-19 Testing: At-home COVID-19 test results, where both specimen collection and testing are conducted at home, are not recorded or reported to public health for the purpose of public health follow-up. Only individuals with positive lab-based PCR tests will receive notification for contact tracing guidance. See lab-based Testing sites in the area.

Quarantine/Isolation Guidance:  See the IDPH website for guidance for the general public:

Fully Vaccinated Individuals:  Fully vaccinated individuals do NOT need to quarantine after contact with someone who had COVID-19 unless they have symptoms. However, fully vaccinated people should get tested 5-7 days after their exposure, even if they don’t have symptoms, and wear a mask indoors in around others for 10 days following exposure. More information on CDC guidelines.

Return to Work Letters No Longer Required:  With the shortened isolation and quarantine periods, most businesses and schools are following CDC guidance and are no longer requiring return to work letters.
