The World Animal Health Information System (WAHIS) from WOAH has three main components: an early warning system, a monitoring system, and an annual reporting system. The early warning system publishes daily reports of animal disease events for all 117 WOAH-listed diseases. The criteria for WOAH list inclusion is detailed in the Terrestrial and Aquatic codes. The monitoring system consists of six-monthly reports that describe the WOAH-listed diseases reported in each country/territory. Annual reports are also published for each country/territory. These annual reports contain additional information on the area’s animal population, potential zoonotic diseases, and veterinary capabilities. The WAHIS system can help users understand the animal health situation worldwide.

WOAH was established in 1924, has 182 member countries and is a leading global authority on animal health. WOAH receives its mandate from the World Trade Organization (WTO) Agreement on Sanitary and Phytosanitary Measures. All the information in WAHIS is reported by Veterinary Services of member countries and territories.
