The World Health Organization (WHO) is building a better future for people everywhere. Health lays the foundation for vibrant and productive communities, stronger economies, safer nations and a better world. Our work touches lives around the world every day - often in invisible ways. As the lead health authority within the United Nations (UN) system, we help ensure the safety of the air we breathe, the food we eat, the water we drink and the medicines and vaccines that treat and protect us. The Organization aims to provide every child, woman and man with the best chance to lead a healthier, longer life.
