Three Chicago area schools were closed last week because their water systems had dangerous levels of Legionella, the bacteria that causes Legionnaires Disease. Officials from School District U-46 closed Eastview Middle School, Larkin High School and the Educational Services Center, housing Gifford Street middle and high schools and the Central Schools Program, on Thursday and Friday while cooling towers were cleaned and sanitized.
The closures affected an estimated 3,000 of the district’s 40,000 students and about 300 employees. No illnesses have been reported.
