World Organisation for Animal Health: A Century of Global Veterinary Leadership
The World Organisation for Animal Health (WOAH) stands as one of the oldest intergovernmental organisations in existence, dedicated to the coordination of responses against infectious animal diseases. From its inception during a global pandemic in the early 20th century to its current role as a primary standard-setting body, the organisation has evolved to meet the shifting challenges of global health, trade, and environmental sustainability.
Key Facts
- Founded: January 25, 1924, as the Office International des Epizooties (OIE).
- Primary Mission: Coordinating global responses to infectious animal diseases and improving animal welfare.
- Major Achievement: Official recognition of the global eradication of rinderpest in 2011.
- Key Framework: Recognized by the WTO as the reference organisation for animal health and zoonoses (diseases that jump from animals to humans).
- Current Approach: Implementation of the "One Health" concept, balancing the health of humans, animals, plants, and the environment.
The Founding and Early Years (1920s–1940s)
The catalyst for the organisation's creation was a rinderpest pandemic—a devastating cattle plague. In May 1921, diplomats from 43 countries met at the International Conference for the Study of Epizootics, where they called for a global body to coordinate the fight against infectious animal diseases. This led to the signing of an international agreement on January 25, 1924, establishing the Office International des Epizooties (OIE).
The OIE established its headquarters by the late 1930s, though its operations were severely hindered by the Second World War and the Nazi occupation of Paris in 1940. Following the war, the OIE faced existential challenges with the creation of the Food and Agriculture Organisation (FAO) in 1946 and the World Health Organisation (WHO) in 1948. Despite overlapping goals, strong opposition from OIE Members and Delegates ensured the organisation maintained its distinct functions.

Expansion and International Integration (1950s–1990s)
The mid-century was marked by a shift toward formal collaboration. The OIE signed official agreements with the FAO in 1952 and the WHO in 1960. Additionally, following the 1957 Treaty of Rome, the OIE supported efforts to harmonise animal health legislation within the European Community.
Recognition as a Standard-Setter
The 1990s brought a surge in global recognition. In 1998, the OIE entered a formal cooperation with the World Trade Organisation (WTO). Under the SPS Agreement (Agreement on the Application of Sanitary and Phytosanitary Measures), the OIE was designated as the reference organisation for animal health and zoonoses. This meant that member nations were required to base their sanitary and phytosanitary measures on OIE standards, guidelines, and recommendations.
This newfound importance led to rapid growth; 41 countries joined as members between 1990 and 1999. To better support these members, the organisation established Regional Representations in Asia and the Pacific, Eastern Europe, the Americas, the Middle East, and Africa.
Modern Evolution and the "One Health" Era (2000–Present)
In May 2003, the organisation rebranded as the World Organisation for Animal Health, though it continued to use the OIE acronym until 2022. During this period, it expanded its network of strategic agreements to include the World Bank and the World Veterinary Association.
The Eradication of Rinderpest
One of the organisation's most significant milestones occurred in 2011. Following rigorous control efforts supported by the FAO, OIE Members unanimously adopted a resolution declaring that all 198 countries and territories with rinderpest-susceptible animals were officially free of the disease.
From 2011 to 2015, the 5th Strategic Plan shifted focus toward food security, poverty alleviation, and veterinary public health. Central to this was the One Health concept—an integrated approach recognizing that the health of people is closely connected to the health of animals and our shared environment.

Recent Milestones and Rebranding
In January 2017, the OIE was designated as an organisation entitled to the benefits of the International Organizations Immunities Act by the U.S. administration. In March 2022, a groundbreaking agreement was signed between the FAO, WOAH, UNEP (UN Environment Programme), and WHO to further strengthen the One Health framework.
In May 2022, the organisation officially transitioned from the acronym OIE to WOAH. In 2024, the organisation commemorates its 100th anniversary, marking a century of commitment to global animal well-being.

Frequently Asked Questions
What is the difference between OIE and WOAH?
There is no difference in the organisation itself; WOAH is simply the new acronym adopted in May 2022 to replace the historical acronym OIE (Office International des Epizooties).
What is the SPS Agreement?
The Agreement on the Application of Sanitary and Phytosanitary Measures (SPS Agreement) is a WTO agreement that defines WOAH as the reference organisation for animal health and zoonoses, requiring members to base their health measures on international standards.
What does the "One Health" concept mean?
One Health is a collaborative, multisectoral, and transboundary approach that aims to sustainably balance and optimize the health of humans, animals, plants, and the environment.
Which major animal disease was eradicated through WOAH's efforts?
Rinderpest was officially recognized as eradicated from all 198 susceptible countries and territories in 2011, following a joint effort between WOAH and the FAO.
Why was the organisation founded in 1924?
It was founded in response to a rinderpest pandemic and a call by diplomats from 43 countries to create a global body to coordinate responses to infectious animal diseases.
