Classrooms, shared learning equipment and high-touch surfaces like door handles and desks see constant contact throughout a school day, and illness spreads quickly in these settings simply due to the volume of shared contact between students.
A consistent daily cleaning routine covering the basics is the foundation, but a more thorough sanitisation pass, ideally weekly or aligned with the start and end of school terms, addresses the deeper build-up that daily cleaning alone doesn't fully catch.
Flu season and any period of elevated illness in the school community are sensible times to increase sanitisation frequency temporarily, particularly on shared equipment and common areas like libraries and canteens where contact volume is highest.
