This book provides essential guidance to help schools in developing countries to promote and maintain hand hygiene practices, thus reducing the prevalence of infectious diseases such as diarrhoea and respiratory infection that cause both illness and absenteeism. Discussing both the challenges that hinder hand hygiene practices and the opportunities available to promote positive behaviours, it is particularly timely since the onset of the global Covid-19 pandemic, where infection could also be passed on through the hands. Drawing on both evidence-based research and successful interventions in specific countries, the book builds to offer a best-practice manual to address this important issue. This will be ideal reading for public health and community health working in developing regions, as well as those working for NGO's.
