OIE list of aquatic animal diseases
A key purpose of listing a disease in the Aquatic
Code is to ensure transparency of the aquatic
animal health status world-wide, by obliging Member
Countries to report its occurrence to OIE.
The OIE collates and disseminates the information
received in reports on the status of those listed
diseases in Member Countries (WAHIS and WAHID).

“The notification of a disease may have a negative impact on the economic performance
of a country (e.g. by causing loss of export markets).”
“However, new information technologies and practices make it difficult for governments to hide occurrences of serious notifiable diseases”
![Page 8: OIE Disease List/Criteria for · PDF fileOIE Disease List/Criteria for Listing Barry Hill Workshop for OIE National Focal Points for Aquatic Animals Dubrovnik, Croatia. ... occurrences](https://reader034.vdocuments.mx/reader034/viewer/2022052608/5aa6f0be7f8b9a424f8bab19/html5/thumbnails/8.jpg)
“A country’s credibility must be based on timely and accurate notification of diseases, and this also gives the respective government a much better position to contain a disease, compared with the situation where it first has to defend a failure to comply with international obligations.”
“Regaining credibility in the face of public knowledge of failure to meet international rules is a costly and time-consuming exercise and can be of the highest political risk for policy makers.”

For the purpose of OIE notification
Disease means clinical or non-clinical
infection with one or more of the
aetiological agents of the diseases
referred to in the Aquatic Code.
