Nations all around the globe celebrate the World Health Day on April 7 every year since 1950, under the sponsorship of the World Health Organization.
This day marks the founding of the World Health Organization in 1950.
It is an occasion to raise awareness of key global health issues. This year's theme is international health security.
The aim of the Day is to urge governments, organizations and businesses to "Invest in health, build a safer future", which is also the motto of this year's celebrations.
The World Health Organization itself is a specialized agency, which is part of the United Nations Organization's structure.
The accent of its work falls on the AIDS and cancer fighting.
