School Exposures

The data on this page represent information collected through contract tracing. Location information is gathered by asking cases to recall locations visited in the 14 days preceding symptom onset or specimen collection if symptoms are not present.  The location name and type of location are entered into a centralized database called Salesforce®.

School data show the number of confirmed and probable cases who listed a school as a place visited, but that does not mean it is where they were infected. Only schools where names have been provided  are included. 

Data completeness is affected by several factors, including ability to reach cases, willingness of cases to report location information, completeness of the location information provided, and differentiation in how contact tracers interpret and enter information provided.

Data for Chicago Public Schools are tracked separately. These data are subject to change as contact tracers enter new information.

Data includes information elicited from cases opened within the previous 30 days from date of update. Data will be updated weekly.
