   The World Health Organization (WHO) is a specialized agency of the United Nations that is responsible for promoting public health worldwide. It was established in 1948 and is headquartered in Geneva, Switzerland.

   The WHO works to improve health outcomes by providing leadership on global health matters, setting norms and standards, and coordinating and monitoring health-related activities around the world. It also provides technical assistance to countries and supports research and development in the field of public health.

   Some of the key areas of focus for the WHO include communicable diseases such as HIV/AIDS, tuberculosis, and malaria; non-communicable diseases such as cancer, diabetes, and heart disease; and health emergencies such as outbreaks of infectious diseases and natural disasters.

   The WHO has a membership of 194 countries and is governed by the World Health Assembly, which meets annually to set policies and approve the organization's budget. The current Director-General of the WHO is Dr. Tedros Adhanom Ghebreyesus, who took office in 2017.
