Parent Message: October 31, 2021

Dear Parents,

Northbrook School District 27 has been advised by the Cook County Department of Public Health to quarantine all students in another third-grade classroom at Shabonee School, out of an abundance of caution, under outbreak criteria. If you have not already been contacted by the District, your child is not required to quarantine. 

All three of our classrooms that required quarantine this past week have been at the third-grade level. We will shift to a remote learning environment for this classroom beginning today, with a return-to-school date of November 15, 2021. The remainder of our classrooms will stay open for in-person instruction.

The CDC and Illinois Department of Public Health define an outbreak as:
1. Multiple cases comprising at least 10% of students, teachers, or staff within a core group; or
2. At least 3 cases within a core group that:
- meet the criteria for probable or confirmed school-associated COVID-19 cases with symptoms onset or positive test results within 14 days of each other;
- are not identified as close contacts of each other in another setting (i.e. household) or outside of the school setting; and
- are epidemiologically linked in the school setting or school-sanctioned extracurricular activity

This classroom will undergo cleaning and disinfection in accordance with CDC guidelines. We ask all families to monitor their children for symptoms and to keep their students home when ill.  We will continue to monitor cases and update the District’s COVID-19 Dashboard

The Shabonee SHIELD Testing results from Friday detected two positive cases schoolwide. The CCDPH reassures us that school is one of the safest places to be given our safety protocols that are in place. In fact, our contact tracing this past week has pointed largely toward out-of-school transmission. SHIELD Testing at Shabonee will continue twice weekly for 28 days, and weekly testing will soon be up and running District-wide. 

Please help your children adhere to COVID safety protocols this weekend as they are celebrating Halloween, and as we approach the upcoming holiday season. We must work together to keep our schools safe. 

Thank you for your partnership.


John Deiter, Ph.D.
Superintendent of Schools
