Water, Sanitation and Hygiene (WASH) in Japanese elementary schools: Current conditions and practices.

Background: Water, sanitation, and hygiene (WASH) is the foundation for preventing infectious diseases, as the current COVID-19 pandemic has shown. WASH is essential for school health, yet there have been very few papers published on WASH in Japanese schools. The objective of this review is to describe the current conditions and practices in Japanese elementary schools using an international framework for WASH in schools and identify implications for handwashing promotion in other areas.
