The acronym for the World Health Organization is WHO. Established in 1948, the WHO is a specialized agency of the United Nations responsible for international public health. Its primary role is to direct and coordinate international health efforts, including disease prevention and health promotion. The organization also provides leadership on global health matters, shapes the health research agenda, and sets norms and standards for health policies. The WHO plays an essential role in responding to health emergencies and coordinating international responses to outbreaks, like the COVID-19 pandemic, while also addressing long-term health challenges around the world.
