Custodians Viamarie Irigoyen and John Tirk use an electrostatic sprayer to disinfect the classrooms at Butler Intermediate High School on Tuesday. The district temporarily closed the school and switched its students to remote instruction after it reached the state-mandated threshold for positive COVID-19 cases within a 14-day period. Students are expected to return to school in person on Friday, as they were before the temporary closure.
