Who we are and
what we do

The Pan American Health Organization (PAHO) is the world’s oldest international public health organization, founded in 1902 in response to a yellow fever outbreak that originated in Latin America and spread to the United States of America. As the specialized health agency of the inter-American system and the Regional Office for the Americas of the World Health Organization (WHO), PAHO has spent over a century turning regional cooperation into concrete health results – from eradicating smallpox to eliminating measles, rubella, and neonatal tetanus, and reducing child mortality, among its other achievements.

Today, PAHO serves 35 Member States and more than 1 billion people through a unique combination of country presence, regional platforms, and technical expertise that no single nation could sustain alone.

A unique institutional identity

PAHO has its own constitution and individual legal personality, making it a distinct entity within the multilateral system. In 1948, PAHO and WHO signed an agreement under which PAHO serves as the WHO Regional Office for the Americas – without altering its institutional autonomy.

This dual identity gives the Region a powerful advantage

PAHO's impact in Member States

Health Ministers across the Americas share how PAHO's technical cooperation strengthens their national health systems.

Jamaica’s partnership with the Pan American Health Organization has delivered real, measurable impact for our people. In 2025, national emergency preparedness was strengthened through targeted training, improved risk analysis, and a more resilient health system. These investments proved critical when Hurricane Melissa struck.

Dr. Christopher Tufton

Minister of Health and Wellness, Jamaica

We want to thank and recognize the joint work: the progress towards universal health; in the prevention and control of diseases, in mental health and better care for non-communicable diseases, as well as in the elimination of communicable diseases; in the area of emergencies and disasters (...) PAHO has been a fundamental ally. We thank PAHO for its commitment to Chile.

Dr. Ximena Aguilera Sanhueza

Minister of Health, Chile (2022 – 2026)

The collaboration of the Pan American Health Organization has accompanied and strengthened initiatives that the Dominican Republic has defined as fundamental to transforming its health system.

Why this matters

  • Record level of voluntary contributions strengthens PAHO’s financial resilience and confirms its role as a trusted partner for sustained health impact.

  • Forward-looking resource mobilization provides greater predictability and stability of funding, enabling PAHO to respond more effectively to health priorities.

  • Longer-term financing commitments extend beyond immediate implementation, securing continuity across future biennium and protecting hard-won health gains.
