The World Health Organization (WHO) is a specialized agency of the United Nations established in 1948. Its primary goal is to promote global health, ensure access to essential healthcare, and coordinate responses to health emergencies. The WHO works with countries to improve health systems, set health standards, and provide guidance on public health issues. The organization focuses on various health topics, including infectious diseases, non-communicable diseases, and mental health. It also plays a crucial role in responding to global health crises, such as the COVID-19 pandemic, by providing resources, information, and support to nations around the world.
