World Health Organization

The World Health Organization (WHO) is a specialized agency of the United Nations, established in 1948, with a primary mission to act as the directing and coordinating authority on international health matters. Its core purpose is to promote health, keep the world safe, and serve vulnerable populations. WHO fulfills this mission through a wide range of concrete functions that span global health governance, disease surveillance, emergency response, normative guidance, technical assistance, and research coordination. One of WHO’s most visible roles is monitoring and responding to disease outbreaks. It maintains a global surveillance network that tracks infectious diseases such as Ebola, COVID-19, influenza, and other emerging pathogens. For instance, the webpage highlights an outbreak of Ebola disease caused by the Bundibugyo virus in the Democratic Republic of the Congo. In such emergencies, WHO deploys rapid response teams, coordinates with national governments, and facilitates the distribution of medical supplies, diagnostics, and vaccines. It also convenes expert panels to evaluate candidate treatments and vaccines, as seen in the news release about candidate therapies for Bundibugyo virus disease. This evidence-based approach ensures that interventions are safe, effective, and ethically sound. Beyond acute emergencies, WHO develops international health regulations, standards, and guidelines that countries adopt to improve public health. It produces the International Classification of Diseases (ICD) used globally for health statistics and billing. It sets norms for drinking water quality, air pollution limits, food safety, and workplace health. Through its World Health Assembly—the decision-making body composed of member states—WHO establishes global health priorities
