3 1. 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).

4 Chapter 1.3. Disease Listed by OIE Diseases of fish (9) Epizootic haematopoietic necrosis Epizootic ulcerative syndrome Infection with Gyrodactylus salaris Infectious haematopoietic necrosis Infectious salmon anaemia Koi herpesvirus disease Red sea bream iridoviral disease Spring viraemia of carp Viral haemorrhagic septicaemia Diseases of molluscs (7) Infection with abalone herpes virus Infection with Bonamia ostreae Infection with Bonamia exitiosa Infection with Marteilia refringens Infection with Perkinsus marinus Infection with Perkinsus olseni Infection with Xenohaliotis californiensis Diseases of crustaceans (8) Crayfish plague (Aphanomyces astaci) Infectious hypodermal and haematopoietic necrosis Infectious myonecrosis Necrotising hepatopancreatitis Taura syndrome White spot disease White tail disease Yellow head disease Diseases of amphibians (2) Infection with Batrachochytrium dendrobatidis Infection with ranavirus

5 2. Criteria for listing aquatic animal diseases How is it decided which diseases to list in the Aquatic Code?

6 2. Criteria for listing an aquatic animal disease Aquatic Code Chapter 1.2. Criteria for Listing Aquatic Animal Diseases

7 2. Criteria for listing an aquatic animal disease Criteria for listing an aquatic animal disease: - Article

8 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. 8

9 2. Criteria for listing an aquatic animal disease 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. 9

10 2. Criteria for listing an aquatic animal disease 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.

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

12 2. Criteria for listing an emerging aquatic animal disease 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.

13 2. Criteria for listing an emerging aquatic animal disease Article - Article 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.

14 2. Criteria for listing an emerging aquatic animal disease 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

15 OIE Listed Diseases and Listing Criteria 26 aquatic animal diseases listed by OIE (2012): 9 diseases of fish 7 disease of molluscs 8 diseases of crustaceans 2 diseases of amphibians Take part in the commenting process for updating the disease list! Modifications possible on annual basis Approved at OIE General Session in May Notification and reporting obligations for new disease listing enters into force on 1 st January the following year

16 3. Disease Notification and Reporting Obligations 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

17 3. Disease Notification and Reporting Obligations The OIE Codes Chapter 1.1. Notification of Diseases and Epidemiological Information Aquatic Code Article : Members shall make 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.

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

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

20 3. Disease Notification and Reporting Obligations Six-monthly report Annual 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 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

21 3. Disease Notification and Reporting Obligations

22 3. Disease Notification and Reporting Obligations OIE launched the 2 nd version of World Animal Health Information System (WAHIS) on 27 Aug 2012.
