The World Animal Health Information System (WAHIS) has been essential in centralising, validating, and publishing timely information on the occurrence of African swine fever (ASF) from the information provided by national Veterinary Authorities. In 2019, 29% of all immediate notifications submitted to the OIE were for ASF.

Through WAHIS, the OIE keeps the international community informed of the evolution of ASF, through alert messages, weekly follow-up reports, weekly regional epidemiological bulletins for Asia and the Pacific, and fortnightly global epidemiological bulletins.
