The following link for educational videos on hygiene were developed by the National Association of School Nurses (NASN). They are provided for school nurses as they return-to-school during COVID-19. The three videos are titled Washing Your Hands, Wearing Cloth Face Coverings, and Staying Home When you are Sick. There are English versions and Spanish versions.
