World Animal Health Information System

WAHIS Portal: Animal Health Data

To enable free access to world animal health data, WOAH provides Internet users with several computer tools designed to answer specific user needs. The World Animal Health Information System – WAHIS portal provides easy access to these tools, for more accurate results while searching for world animal health information.

Guaranteeing transparency of the world animal health situation is one of the primary missions of WOAH. WOAH Members have an obligation to submit information on their animal health situation, and a list of terrestrial and aquatic animal diseases notifiable to WOAH has been established for that purpose. To fulfil this mandate, WOAH regularly adapts the information technology tools of the World Animal Health Information System (WAHIS), which comprises three essential elements:

  1. An early warning system for the immediate management of alert notices for WOAH-listed diseases and emerging diseases.
  2. A monitoring system to manage six-monthly information updates on all WOAH-listed diseases.
  3. Further information provided by National Authorities through annual reports on animal diseases affecting human populations, animal populations and Veterinary Service capacities, such as personnel, laboratory capacity and vaccine production.

In addition, there is WAHIS-Wild, a system which gathers and presents information on wildlife diseases that are not included in the WOAH List but are considered to require surveillance. These diseases are not subject to compulsory notification, but WOAH Members are encouraged to provide information on them voluntarily, if they are of significant interest for animal health knowledge.

The WAHIS portal provides access to a list of real-time alert notices and the following information:
