The World Health Organization (WHO) is a specialized agency of the United Nations that is responsible for promoting public health worldwide. Founded in 1948, its headquarters are located in Geneva, Switzerland. The organization works with governments and other partners to improve health outcomes and address health emergencies, such as disease outbreaks, natural disasters, and humanitarian crises. Its areas of focus include disease prevention, health promotion, and improving access to healthcare services, particularly in low- and middle-income countries. WHO sets international standards for healthcare, conducts research to develop evidence-based policies, and provides technical support to countries to help them strengthen their healthcare systems. Some of the major health issues that WHO has tackled in recent years include the COVID-19 pandemic, Ebola outbreaks, non-communicable diseases, and maternal and child health. WHO also plays a leading role in promoting global health equity and advancing the Sustainable Development Goals related to health.
