WHO began when their Constitution came into force on 7 April 1948 – a date we now celebrate every year as World Health Day. WHO works worldwide to promote health, keep the world safe, and serve the vulnerable. WHO goal is to ensure that a billion more people have universal health coverage, to protect a billion more people from health emergencies, and provide a further billion people with better health and well-being. WHO, as the directing and coordinating authority on international health within the United Nations system, adheres to the UN values of integrity, professionalism and respect for diversity. The values of the WHO workforce furthermore reflect the principles of human rights, universality and equity established in WHO’s Constitution as well as the ethical standards of the Organization. These values are inspired by the WHO vision of a world in which all peoples attain the highest possible level of health, and our mission to promote health, keep the world safe and serve the vulnerable, with measurable impact for people at country level. We are individually and collectively committed to put these values into practice.
