World Health Day is observed on April 7 of each year. Since the celebration's conception at the First Health Assembly in 1948 and its implementation in 1950, it has attempted to raise awareness of a particular health topic to draw attention to a key area of concern for the World Health Organisation.

This has raised awareness of significant health concerns during the past 50 years, including mental health, maternity and child care, and climate change. The festival is highlighted by after-hours events and offers a chance to draw attention to these crucial facets of global health on a global scale.
