The acronym "WHO" stands for the World Health Organization. This is a specialized agency of the United Nations responsible for international public health. Established in 1948, its primary role is to coordinate international health activities and to help countries improve their health systems. The WHO provides leadership on global health matters, shapes the health research agenda, sets norms and standards, and monitors and assesses health trends.

The other options do not accurately represent globally recognized organizations within the realm of public health. For example, while "Western Hemisphere Organization" might imply a regional body, it does not have the same scope or recognition as the WHO. "World Hygiene Organization" and "Wellness Health Outreach" are not established organizations in public health and do not exist in the same capacity or with the same impact as the World Health Organization. Understanding the role of WHO is crucial for anyone involved in public health, as it provides vital information and resources that influence health policies worldwide.
