3. 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). 1. OIE List of aquatic animal diseases

4. 1.3.1 Diseases of fish (10) Epizootic haematopoietic necrosis Infection with Aphanomycesinvadans (Epizootic ulcerative syndrome)* Infection with Gyrodactylussalaris Infection with HPR-deleted or HPR0 infectious salmon anaemia virus* Infection with salmonidalphavirus Infectious haematopoietic necrosis Koiherpesvirus disease Red sea bream iridoviral disease Spring viraemia of carp Viral haemorrhagicsepticaemia Chapter 1.3.

8. 8 2. Criteria for listing aquatic animal diseases New article (1.2.1.) providing clarifications regarding the purpose of listing emerging aquatic animal diseases Article 1.2.2. – Criteria for listing an aquatic animal disease For diseases listed under this article, a disease-specific Aquatic Code chapter provide standards for safe international trade Article 1.2.3 – Criteria for listing an emerging aquatic animal disease For diseases listed under this article, there is no disease-specific Aquatic Code chapter and thus no standards for trade Trade requirements can be institute only where these are justified by science-based risk assessment The purpose if listing emerging disease is to collect relevant information so to later consider the listing in accordance with article 1.2.2.

9. Criteria for listing an aquatic animal disease: - Article 1.2.2. 2. Criteria for listing aquatic animal diseases

10. 10 2. Criteria for listing an aquatic animal disease A disease proposed for listing should meet all the relevant criteria as set out in: a)Consequences b)Spread c)Diagnosis Such proposals should be accompanied by a case definition for the disease.

11. 11 A.Consequences 1.The disease has been shown to cause significant production losses at a national or multinational (zonal or regional) level. OR 2.The disease has been shown to or scientific evidence indicates that it is likely to cause significant morbidity or mortality in wild aquatic animal populations. OR 3.The agent is of public health concern. 2. Criteria for listing an aquatic animal disease

12. B. Spread 4.Infectious aetiology of the disease is proven. OR 5.An infectious agent is strongly associated with the diseases, but the aetiology is not yet known. AND 6.Likelihood of international spread, including via live animals,their products or fomites. AND 7.Several countries or countries with zones may be declared free of the disease based on the general surveillance principles outlined in Chapter 1.4 of the Aquatic Code. 2. Criteria for listing an aquatic animal disease

13. C. Diagnosis 8.A repeatable and robust means of detection/diagnosis exists. 2. Criteria for listing an aquatic animal disease

14. Emerging disease means a newly recognised infection resulting from the evolution or change of an existing pathogenic agent, a known infection spreading to a new geographic area or population, or a previously unrecognised pathogenic agent or a disease diagnosed for the first time and which has a significant impact on aquatic animal or public health. 2. Criteria for listing an emerging aquatic animal disease

15. - Article 1.2.2. 2. Criteria for listing an emerging aquatic animal disease Article 1.2.3 A newly recognised disease or a known disease behaving differently may be proposed for listing if it meets the criteria; Such proposals should be accompanied by a case definition for the disease.

16. 1. The infectious aetiology of the disease is proven OR 2. An infectious agent is strongly associated with the disease, but the aetiology is not yet known AND 3. The agent is of public health concern OR 4. Significant spread in naive populations of wild or cultured aquatic animals 2. Criteria for listing an emerging aquatic animal disease

17. 28 aquatic animal diseases listed by OIE (2013): –10 diseases of fish –8 disease of molluscs –8 diseases of crustaceans –2 diseases of amphibians Take part in the commenting process for updating the disease list! OIE Listed Diseases and Listing Criteria – Summary Notification and reporting obligations for new disease listing enters into force on 1 st January the following year Modifications possible on annual basis Approved at OIE General Session in May

18. Since its creation in 1924 both the OIE and its Members have unconditional duties to disclose all relevant information on animal diseases. These obligations are stated in The OIE Organic Statutes (1924) The OIE Codes 3. Disease Notification and Reporting Obligations

19. The OIE Aquatic Code  Chapter 1.1. Notification of Diseases and Epidemiological Information  Article 1.1.2. : ‘Members shallmake available to other Members, through the OIE, whatever information is necessary to minimise the spread of aquatic animal diseases and their aetiological agents and to assist in achieving better worldwide control of these diseases.’ 3. Disease Notification and Reporting Obligations

20. Reporting (regular and immediate notification) of aquatic animal diseases does not require the presence of clinical disease or mortality. The Aquatic Code (Article 1.1.2.) clarifies that: ‘The detection of an infectious agent of a listed disease in an aquatic animal should be reported, even in the absence of clinical signs of disease.’ 3. Disease Notification and Reporting Obligations

21.  Immediate notificationof disease, infection or unusual epidemiological events  Weekly reports: Follow-ups to the immediate notification  Final report : - if the outbreaks have ended - if the situation becomes endemic  Six-monthly report  Annual report Early warning Monitoring 3. Disease Notification and Reporting Obligations Type of Reports

22. Six-monthly report The absence or presence of OIE-listed diseases Evolution of all listed diseases Findings of epidemiological importance to other Members with respect to diseases not listed by OIE 3. Disease Notification and Reporting Obligations Annual report The sum of information of the two six-monthly reports of a given year Non OIE-listed diseases Human resources in Veterinary Services National Reference Laboratories Animal census (by first administrative division) Zoonoses (human cases and deaths) Production of vaccines
