International Agreement for the creation of an Office International des Epizooties

The World Organization for Animal Health (WOAH) tracks and reports epizootic disease outbreaks, sets animal health and safety standards, and provides technical support for infrastructure development and outbreak response. WOAH was titled the Office International des Epizooties (OIE) until 2003, and changed its acronym to WOAH in 2022. WOAH regularly updates a public tracker documenting epizootic outbreaks and efforts to contain them.

The state has accepted, approved, ratified, or is otherwise party to the agreement, indicating consent to be bound to the agreement.

The state has signed, but not yet ratified or become an official party to the agreement. Where the signature is subject to ratification, acceptance or approval, the signature does not establish the consent to be bound. However, it is a means of authentication and expresses the willingness of the signatory state to continue the treaty-making process. The signature qualifies the signatory state to proceed to ratification, acceptance or approval. It also creates an obligation to refrain, in good faith, from acts that would defeat the object and the purpose of the agreement.

The state has not taken any actions with regard to the agreement.
