April 7 is World Health Day, a celebration of the founding of the World Health Organization (WHO). Sometimes in our day-to-day public health work, the way we deliver messages can create more obstacles than we realize. Changing behaviour does not come easily to anyone and a behaviour change project requires great insight into people's lives to understand the barriers to change.
My project has its roots with my colleagues at the Guatemalan Ministry of Health who, after the initial success in the roll-out of the zinc and oral rehydration salts (ORS) treatment program for diarrhea, started thinking of ways to improve the program and its potential impact. They had the initial idea for what's become the cajita salvavida or "Life-saving Box."
