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).
Chapter 1.3. Diseases Listed by OIE
1.3.1 Diseases of fish (10)
• Epizootic haematopoietic necrosis

Aphanomycesinvadans(Epizootic
ulcerative syndrome)*

decided which
diseases to list
in the Aquatic
Code?

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.

2. Criteria for listing aquatic animal diseases
Criteria for listing
an aquatic animal
disease:
- Article 1.2.2.
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.
10
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.
11
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.
2. Criteria for listing an aquatic animal disease
C. Diagnosis
8. A repeatable and robust means of detection/diagnosis exists.
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.
2. Criteria for listing an emerging aquatic animal disease
Article- Article
1.2.3 1.2.2.
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.
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
OIE Listed Diseases and Listing Criteria – Summary

–
–
–

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 1st January the following year
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
3. Disease Notification and Reporting Obligations
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
• Reporting (regular and immediate notification) of aquatic
animal diseases does not require the presence of clinical
disease or mortality.
• TheAquatic 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
Type of Reports
 Immediate notificationof disease, infection
or unusual epidemiological events
 Weekly reports: Follow-ups to
Early warning
the immediate notification
 Final report :
- if the outbreaks have ended
- if the situation becomes endemic
Monitoring
 Six-monthly report
 Annual report
3. Disease Notification and Reporting Obligations
Six-monthly report
The absenceor 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
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
