FCPHD reports both confirmed and probable case data as recently recommended by the CDC. Total cases include confirmed and probable cases. A confirmed case is someone who has tested positive for COVID-19 through a viral test, also called a molecular test. A viral test alone, is enough to be classified as a laboratory confirmed case. An example of a probable case is an individual who tests positive for COVID-19 through other testing methods, such as a “Rapid” test, or antigen test. Both confirmed and probable cases are treated the same with regards to isolation and contact tracing. For more information on case definitions and criteria, including probable cases, click here.
Please note, zip code data will not be shown unless a zip code has six or more confirmed cases. This is consistent with Collection, Disclosure, and Confidentiality of Health Statistics (77 Ill. Adm. Code 1005). Zip code areas 61773, 60962, 60959, 60957, 60952, 60946, 60936, and 60919 are being reported.
