The World Health Organization (WHO) is a specialized agency of the United Nations responsible for international public health. Established on April 7, 1948, with its headquarters in Geneva, Switzerland, WHO's primary objective is to promote health, monitor global health trends, and provide leadership on matters critical to public health.
WHO operates as a coordinating authority for international health within the United Nations system, working closely with governments, non-governmental organizations (NGOs), and other international partners to address health challenges worldwide. The organization's Constitution states that its objective is "the attainment by all peoples of the highest possible level of health."
One of WHO's key functions is to provide technical assistance and guidance to countries in areas such as disease prevention, health promotion, and health systems strengthening. It develops evidence-based guidelines and recommendations, conducts research, and disseminates information to support countries in improving their health outcomes and reducing health inequalities.
WHO's work covers a wide range of health issues, including infectious diseases (such as HIV/AIDS, tuberculosis, malaria, and COVID-19), noncommunicable diseases (such as cancer, diabetes, and cardiovascular diseases), maternal and child health, nutrition, mental health, environmental health, and emergency preparedness and response.
The organization is governed by the World Health Assembly (WHA), which is composed of representatives from all WHO member states and meets annually to set policies and approve the organization's budget and program priorities. The WHA is supported by an Executive Board consisting of 34 member states elected for three-year terms.
In addition to its normative and technical work, WHO plays a crucial role in coordinating international responses to health emergencies and outbreaks. It leads global efforts to contain outbreaks of infectious diseases, provides guidance to countries on preparedness and response measures, and mobilizes resources and expertise to support affected populations.
Despite its important mandate and achievements, WHO faces various challenges, including limited funding, political pressures, and the complexity of global health issues. However, the organization remains committed to its mission of promoting health, keeping the world safe, and serving the vulnerable, guided by the principles of equity, solidarity, and universal health coverage.
