The Chicago and Boston public school systems will be closed beginning next week due to coronavirus concerns, officials in both cities said Friday.

Boston schools will be closed beginning Tuesday and through April 27, Mayor Marty Walsh announced, according to Boston25News.

Illinois Gov. J.B. Pritzker made the decision to shutter all schools statewide, a move that impacts some two million students.

Like Mayor de Blasio, Chicago Mayor Lori Lightfoot had resisted the move for more than a week, arguing that the schools provided crucial social services to the city’s 350,000 kids — many of them low income.

“To be clear, I understand the gravity of this action, and what it means for every community in our state,” Pritzker said, according to the Chicago Sun-Times. “This is the right thing to do, to protect our students and their teachers, school workers and parents.”

Despite Lightfoot’s resistance, the city’s teachers union called for a shutdown earlier Friday.
