World Health Day is celebrated every year on 7 April, under the sponsorship of the World Health Organization (WHO).

In 1948, the World Health Organization held the First World Health Assembly. The Assembly decided to celebrate 7 April of each year, with effect from 1950, as the World Health Day. The World Health Day is celebrated to create “awareness of a specific health theme to highlight a priority area of concern for the World Health Organization (WHO)”. Activities – related to that particular theme and the resources provided – continue beyond 7 April, that is, the designated day for celebrating the World Health Day.
