The World Health Day is held to mark WHO's founding, and is seen as an opportunity by the organization to draw worldwide attention to a subject of major importance to global health each year. The WHO organizes international, regional and local events on the Day related to a particular theme. Resources provided continue beyond 7 April, that is, the designated day for celebrating the World Health Day.
World Health Day is acknowledged by various governments and non-governmental organizations with interests in public health isssues, who also organize activities and highlight their support in media reports.
The WHO's constitution states that its objective "is the attainment by all people of the highest possible level of health." In 1986, the WHO said that health is "a resource for everyday life, not the objective of living. Health is a positive concept emphasizing social and personal resources, as well as physical capacities." (With material from: Wikipedia)
