PAHO is the specialized international health agency for the Americas.
It works with countries throughout the region to improve and protect people's health.
PAHO engages in technical cooperation with its member countries to fight communicable and noncommunicable diseases and their causes, to strengthen health systems, and to respond to emergencies and disasters. Under the leadership of its 52 member countries and territories, PAHO sets regional health priorities and mobilizes action to address health problems that respect no borders and that, in many cases, jeopardize the sustainability of health systems.
PAHO wears two institutional hats: it is the specialized health agency of the Inter-American System and also serves as Regional Office for the Americas of the World Health Organization (WHO), the specialized health agency of the United Nations. From its Washington, D.C., headquarters, 27 country offices and three specialized centers in the region, PAHO promotes evidenced-based decision-making to improve and promote health as a driver of sustainable development.
