Reopening June 11 If half of residents 16 and older have received at least one vaccine dose and coronavirus metrics have been stable or falling for 28 days. Masks mandatory indoors

Gov. J.B. Pritzker, a Democrat, announced that the state would move into the Bridge Phase of reopening, which allows for relaxed capacity limits, on May 14. The state could move into Phase 5 of reopening, which removes capacity limits entirely, as soon as June 11. More details ›

About this data Sources: State and local health agencies (cases, deaths); U.S. Department of Health and Human Services (tests, hospitalizations). The seven-day average is the average of a day and the previous six days of data. Currently hospitalized is the most recent number of patients with Covid-19 reported by hospitals in the state for the four days prior. Dips and spikes could be due to inconsistent reporting by hospitals. Hospitalization numbers early in the pandemic are undercounts due to incomplete reporting by hospitals to the federal government. Tests represent the number of individual P.C.R. viral test specimens tested by laboratories and state health departments and reported to the federal government.

Outbreak clusters

Since March 2020, The Times has paid special attention to cases in the types of places with some of the worst outbreaks, like nursing homes, food processing plants and correctional facilities.

Cases Connected To Location Cases
University of Illinois Urbana-Champaign Champaign, Ill. 6,693
Illinois State University Normal, Ill. 2,392
University of Illinois at Chicago Chicago, Ill. 1,654
Northwestern University Evanston, Ill. 1,216

About this data Information on cases linked to these places comes from official releases by governments, companies and institutions directly. The Times is publishing lists of groupings of 50 or more cases related to a specific site, workplace or event.

About the data

In data for Illinois, The Times primarily relies on reports from the state, as well as health districts or county governments that often report ahead of the state. Illinois typically releases new data each day. Weekend counts may be lower because fewer sources report to the state. The state reports cases and deaths based on a person’s permanent or usual residence. The state also includes nonresidents diagnosed in the state, but The Times excludes this category since nonresidents are likely also counted in their home state.

The Times has identified the following reporting anomalies or methodology changes in the data:

  • April 13, 2021: The reported number of tests likely includes many older tests.
  • Jan. 22, 2021: Illinois began including probable deaths as probable cases, resulting in a one-day increase in cases.
  • Sept. 4, 2020: Illinois announced many backlogged cases from earlier in the week after resolving a data processing slowdown.
  • June 8, 2020: Illinois began reporting probable cases and deaths.
  • On Nov. 6, Illinois began reporting probable cases and deaths at the county level, resulting in one-day increases for many counties.

The tallies on this page include cases and deaths that have been identified by public health officials as probable coronavirus patients. The Illinois Department of Health releases new data for probable cases once a week, which can cause a single-day spike in the number of reported cases.

Confirmed cases and deaths, which are widely considered to be an undercount of the true toll, are counts of individuals whose coronavirus infections were confirmed by a molecular laboratory test. Probable cases and deaths count individuals who meet criteria for other types of testing, symptoms and exposure, as developed by national and local governments.

Governments often revise data or report a single-day large increase in cases or deaths from unspecified days without historical revisions, which can cause an irregular pattern in the daily reported figures. The Times is excluding these anomalies from seven-day averages when possible.
