COVID-19: Answer the Call to Help Slow the Spread

Answer the Call

DuPage County Health Department (DCHD) Case Investigators and Contact Tracers 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.

*Close contacts are individuals who have been within 6 feet for a cumulative total of 15 minutes or more over a 24-hour period (for example, three individual 5-minute exposures for a total of 15 minutes) of an infected person (laboratory-confirmed or a clinically compatible illness). An infected person can spread COVID-19 starting 2 days before they have any symptoms (or, for asymptomatic person, 2 days before the positive specimen collection date), until they meet criteria for discontinuing home isolation.

  • Exception: In the K–12 indoor classroom setting, the close contact definition excludes students who were within 3 to 6 feet of an infected student (laboratory-confirmed or a clinically compatible illness) if both the infected student and the exposed student(s) correctly and consistently wore well-fitting masks the entire time. This exception does not apply to teachers, staff, or other adults in the indoor classroom setting.

Staff will ensure they have the necessary support and resources.
