The World Health Organization (WHO) was established in 1948 as a specialized agency of the United Nations, three years after its initial founding. It focuses on connecting nations across the globe to promote health, serve the vulnerable, and coordinate the world's response to health emergencies. WHO is the main health-related arm of the UN, and plays roles in expanding universal health coverage, designing rapid response teams, and developing preventative care measures. Its goal for the next few years is to focus on the Triple Billion targets, which intend to achieve health and wellbeing across the globe using science-backed policies and initiatives.
