The WHO is considered as the acronym for the World Health Organization, it is a specialized agency within the United Nations system. It was created in April 1948 to act as the directing and coordinating authority on health matters and public health at the international level. WHO’s mission is to achieve the highest possible level of health for all peoples, so that they can enjoy socially and economically productive lives. WHO provides its constructive and technical services, helping to train specialist personnel in general health matters.

This organization has two main functions: technical cooperation with the countries and directing international cooperation in the area of ​​health by adopting, when necessary, specific measures in the area of ​​health, developing and transferring technology, and disseminating information through publications, preparing regulations, norms, plans and policies and monitoring and follow-up models, as well as promoting research and technical consultations.

As a result of globalization, communicable diseases such as AIDS or diseases that are easily spread worldwide, such as the A1N1 flu, require coordinated international responses that only a world organization like the WHO can help implement.

WHO provides specialized advice on epidemiological control issues, communicable diseases, and emergency health training. Its activities include the supply of medicines and emergency material, the displacement of emergency evaluation missions and technical support.

The structure of the WHO is made up of a main and highest body known as the World Health Assembly, which determines the rules of action of the organization, is represented by its 193 member countries, which meet annually; the Executive Council which acts as the executive body of the Assembly; and the Secretariat, which is composed of a Director General and the necessary technical and administrative staff.

WHO has its headquarters in Geneva, Switzerland, and maintains continental regional offices in Southeast Asia (New Delhi, India), the eastern part of the Mediterranean (Cairo, Egypt), Europe (Copenhagen, Denmark), Africa (Brazzaville, Republic of Congo), the Americas (Washington DC, United States) and the Western Pacific (Manila, Philippines).

For its health and humanitarian work, in 2009, the institution was awarded the Prince of Asturias Award for International Cooperation. In 2000, at the Millennium General Assembly of the United Nations, a series of health objectives were defined to be achieved by 2015, deciding that the WHO would monitor these issues.
