The World Health Organization (WHO) celebrates the anniversary of its foundation, with 193 member states, as the directing and coordinating authority for health within the United Nations system. Founded in 1948, WHO is responsible for providing leadership on global health matters, shaping the health research agenda, setting norms and standards, articulating evidence-based policy options, providing technical support to countries and monitoring and assessing health trends.

This year, WHO aims to focus on the close links between our surrounding environment and our health. Today’s campaign will urge individuals, communities, governments and organizations around the world to share their stories of the steps they are taking to protect both the environment and our health.
