COVID-19 School Aged Metrics and School Outbreaks

IDPH is monitoring several trends at the county, regional, and statewide level. This page includes information about school-aged cases and outbreaks in schools. Data for school-aged cases include the number of new cases reported each week by county among age groups 5-11 years, 12-17 years, and 18-22 years. Not all cases among those aged 5-17 years are associated with schools.

Outbreak information is reported once clusters of cases are confirmed to be linked by location and time (within 14 days). Some outbreaks are pending processing and evaluation and will be added as more complete information is available. The outbreak information is reported by local health departments to the Illinois Department of Public Health through an outbreak reporting system. 

Specific outbreaks included are those that have been identified by the local health department to have two or more COVID-19 cases who may have a shared exposure on school grounds and are from different households. Case counts for school-related outbreaks also include those associated with before and after school programs (e.g., school-sponsored sports). These outbreaks do not include secondary cases that may occur in a household member who has not been on school grounds.

All data is provisional and subject to updating as more information becomes available. Data are updated once a week on Fridays. Last updated: ####
