How does contact tracing work?
We all need to work together to help slow the spread of COVID-19. Contact tracing slows the spread of COVID-19 by:
- Reaching out to people with COVID-19 to identify everyone they had close contact with during the time they may have been infectious.
- Letting people know they may have been exposed to COVID-19 and should monitor their health for signs and symptoms of COVID-19.
- Helping people who may have been exposed to COVID-19 get tested.
- Monitoring contacts for signs and symptoms of COVID-19.
- Connecting contacts with services they might need so they can self-isolate if they have COVID-19 or self-quarantine if they are a close contact of someone who has COVID-19

GET TESTED
Getting tested is one of the most important steps you can take to help stop the spread of COVID-19. Combined with contact tracing and proper isolation, it protects you and those closest to you. Visit our testing page for information about testing for COVID-19 in suburban Cook County.
RETRACE STEPS
Write down your travels and close contacts prior to finding out you were exposed to someone who tested positive for COVID-19. Notify your close contacts right away so they can take precautions to get tested, stay home and monitor for symptoms if you test positive.
STAY HOME
Quarantine keeps someone who might have been exposed to COVID-19 away from others. Quarantine helps prevent spread of disease that can occur before a person knows they are sick. To prevent spreading the virus, stay home, away from others and monitor your symptoms.
Rest Assured
Your private health information is secured and always kept completely confidential. We will not ask for your social security number. We will not share your name with anyone, including your close contacts, law enforcement, debt collection agencies or immigration.
