World Health Day is a global health awareness day celebrated every year on 7 April, under the sponsorship of the 

World Health Organization (WHO), as well as

other related organizations.  In 1948, the

WHO 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 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.
