CDC released consolidated, evidence-based guidance for preventing the spread of infections in K-12 schools. The guidance includes everyday actions that schools can take to prevent and control the spread of respiratory and stomach viruses, such as influenza and norovirus, and bacterial illness, such as strep throat. This guidance is designed to maximize school attendance and its benefits for all students, while also preventing the spread of infectious diseases. Being in school provides many benefits, including ongoing learning and social and emotional development. This guidance is being released for consideration for the 2024 – 2025 school year. As school administrators are closing out the current school year and planning for the new school year in the fall, CDC is providing the guidance now to ensure it can be part of those back-to-school preparations. The strategies found in the new guidance are based on research and expertise CDC gained from decades of working to prevent disease transmission in school settings. They include:

• Teach and reinforce proper hand washing and respiratory etiquette.

• Take steps for cleaner air by improving ventilation in schools. Schools should consider ventilation enhancements and design when undergoing remodeling or when undertaking new building construction to optimize clean air.

• Clean, sanitize, and disinfect, when appropriate.

• Promote vaccinations for students and staff.
