Statewide Reopening Metrics

IDPH continues to monitor key indicators to identify early increases of virus transmission in Illinois, potentially signifying resurgence. These indicators are calculated for the entire state. IDPH will monitor if these indicators show an increase in the COVID-19 disease burden with a simultaneous decrease in hospital capacity. 

Indicators are calculated daily for Illinois based on the most current, complete data. Each indicator is monitored for the trend over 28 days to evaluate the COVID-19 disease burden and hospital resource capacity. By applying the same metrics across Illinois, IDPH uses a standardized approach to monitor the state as a whole.

On June 11, 2021, Illinois moved into Phase 5 of the Restore Illinois Plan. IDPH will continue to track the vaccinations rates and hospital capacity metrics, and cases over 28-day monitoring periods. New evidence concerning variants, vaccine effectiveness, or waning immunity could substantially and quickly increase COVID-19 hospitalizations and will be taken into consideration, in addition to the metrics being monitored.

Data are provisional and are updated daily. Data Updated: ##/##/####

Methodology

Vaccination Rate (First Dose)

Vaccine administrations are reported to the Illinois-Comprehensive Automated Immunization Registry Exchange (I-CARE). Administered vaccines are reported based on the date IDPH receives the vaccination record.

Calculation: [Total First Dose of Vaccine Administered in persons 65+] / [population 65+]
Population 65+ = 1,992,961

COVID-19-like-Illness (CLI) Admissions

COVID-19-like-Illness (CLI) new hospital admissions are reported to the Illinois Syndromic Surveillance System. Visits are defined as CLI if the patient presents with a fever AND either cough, difficulty breathing or is given a diagnosis of COVID-19. Data is provisional, and a three-day lag after admission is used to allow time for IDPH to receive more complete data before analysis is performed.

Hospital Beds Occupied by a COVID-19 Patient

The number of COVID-19 patients in hospital is reported daily by each hospital to IDPH EMResouces and represents the daily total number of hospital beds occupied by a suspected or confirmed COVID-19 patient.

Number of Deaths

Deaths of lab-confirmed cases of COVID-19 are reported in the Illinois-National Electronic Disease Surveillance System (I-NEDSS) as the underlying cause of death or the contributing cause of death, confirmed either by investigations or record match with the Illinois Vital Records data.

Intensive Care Unit (ICU) Beds Percent Availability

Intensive Care Unit (ICU) beds availability is reported daily by each hospital to IDPH EMResources and represents the number of ICU hospital beds that are empty.

Calculation: ICU availability = [Sum of ICU beds available for 7 days] / [Total ICU beds for 7 days] x 100

Number of New Cases

COVID-19 cases are newly identified lab-confirmed cases of COVID-19 that are reported in the Illinois-National Electronic Disease Surveillance System (I-NEDSS).
