3 Introduction 1st OIE historical objective: To ensure transparency in the global animal disease situation, including zoonoses

4 Obligation for notification
By deciding to join the OIE, a Member agrees to fulfil its international commitment to notify to the OIE - as laid down in the Chapter of the OIE’s CODE (“Notification and Epidemiological Information”)

5 Meaning of ‘Notification’
The procedure by which: the Veterinary Authority informs OIE Headquarters OIE Headquarters informs Veterinary Authority, of the suspicion or confirmation of an outbreak of disease or other epidemiological event, according to the provisions of the OIE’s Codes Each Veterinary Authority OIE Headquarters All Member Countries Veterinary Authority

7 OIE list of notifiable diseases for terrestrial animals
Vulnerability Risk Summary Form Assessment Form A single list (2005) Criteria for listing diseases (infections): Capacity for international spread Capacity for significant spread within naïve populations Zoonotic potential Emerging disease Comments (with copyright) / Commentaires (soumis au Copyright) : [source : Objective 1 : To ensure transparency in the global animal disease situation Each Member undertakes to report the animal diseases that it detects on its territory. The OIE then disseminates the information to other countries, which can take the necessary preventive action. This information also includes diseases transmissible to humans and intentional introduction of pathogens. Information is sent out immediately or periodically depending on the seriousness of the disease. This objective applies to disease occurrences both naturally occurring and deliberately caused. Dissemination is via the OIE Web site, and the following periodicals: Disease Information, published weekly and the annual compilation World Animal Health. Objectif 1 : Garantir la transparence de la situation des maladies animales et des zoonoses dans le monde Chaque Pays Membre s'engage à déclarer les maladies animales qu'il détecte sur son territoire. L'OIE diffuse alors l'information à tous les autres pays afin qu'ils puissent se protéger. Cette information concerne également les maladies transmissibles à l'homme. Elle est diffusée en urgence ou de façon différée selon la gravité de la maladie. Ces objectifs de surveillance et de suivi s'appliquent à la fois aux événements sanitaires naturels ou intentionnels. Les supports de diffusion sont le site Web de l'OIE, le courrier électronique et les périodiques suivants : Informations sanitaires, publiées chaque semaine, et le recueil annuel Santé animale mondiale.

8 Decision Tree used to determine the list
INTERNATIONAL SPREAD Has international spread been proven on 3 or more occasions? OR Are more than 3 countries with populations of susceptible animals free of the disease or facing impending freedom (based on Code provisions, especially Appendix 3.8.1)? OR Do OIE annual reports indicate that at least 3 countries with susceptible populations are reporting absence of the disease? EMERGING (A newly recognised pathogen or known pathogen behaving differently) Is there rapid spread or apparent zoonotic properties? EXCLUDE NO YES ZOONOTIC Has transmission to humans been proven? (with the exception of artificial circumstances) AND Is human infection associated with severe consequences? (death or prolonged illness) SIGNIFICANT SPREAD IN NAIVE POPULATIONS Does the disease exhibit significant mortality at level of a country or zone? OR Does the disease exhibit significant morbidity at the level of a country or zone? NO INCLUDE YES NO EXCLUDE YES INCLUDE

10 Contents Introduction OIE’s list of diseases Notification procedures
Outputs of WAHIS=WAHID Interface Transparency Conclusion

11 Steps in reporting Immediate notification of disease, infection or unusual epidemiological events Weekly reports: Follow-up to the immediate notification Final report : - if the outbreaks have ended - if the situation becomes endemic Six-monthly report Annual report

12 Immediate notification
What needs immediate notification - within 24 hours? 1 - The first occurrence of a listed disease or infection in a country or zone/compartment 2 - The re-occurrence of a listed disease or infection in a country or zone/ compartment following a report declaring previous outbreak(s) eradicated 3 - The first occurrence of a new strain of a pathogen of a listed disease in a country or zone/compartment

13 Immediate notification (cont.1)
4 - A sudden and unexpected increase in morbidity or mortality caused by an existing listed disease 5 - Evidence of change in the epidemiology of a listed disease (e.g. host range, pathogenicity, strain of causative pathogen), in particular if there is a zoonotic impact. 6 - An emerging [non listed] disease with significant morbidity / mortality or zoonotic potential

14 Unusual epidemiological event
OIE listed disease / infection New Disease New Infection Unusual epidemiological event Emerging disease Immediate notification Control measures Report Type of event Source of infection Nature of diagnosis Laboratory tests Outbreak 2 Outbreak 1 Outbreak n Location Animals Affected

18 on the absence or presence of listed diseases
Six-monthly Report Started July 2005 on the absence or presence of listed diseases Part 1: Qualitative information disease occurrence, control, prophylaxis and prevention measures, indication of the type of report to use to notify diseases or infections/infestations present in the country (=> part 2) Comments (with copyright) / Commentaires (soumis au Copyright) : [source : Objective 2 : To collect, analyse and disseminate veterinary scientific information The OIE collects and analyses the latest scientific information on animal disease control. This information is then made available to the Members to help them to improve the methods used to control and eradicate these diseases. Guidelines are prepared by the network of 156 OIE Collaborating Centres and Reference Laboratories across the world. Scientific information is also disseminated through various works and periodicals published by the OIE, notably the Scientific and Technical Review (3 issues a year). Objectif 2 : Collecter, analyser et diffuser l'information scientifique vétérinaire L'OIE collecte et analyse toutes les nouvelles informations scientifiques relatives à la lutte contre les maladies animales. Il les fournit ensuite aux Pays Membres pour qu'ils améliorent les méthodes qu'ils utilisent pour contrôler et éradiquer ces maladies. Des lignes directrices sont préparées à cet effet par le réseau des 156 Centres Collaborateurs et Laboratoires de Référence de l'OIE présents dans le monde entier. L'information scientifique est aussi diffusée grâce à différents ouvrages et périodiques édités par l'OIE, notamment la Revue scientifique et technique (3 numéros par an).

32 Transparency & competence
The quality of the information provided to the OIE reflects the degree of knowledge of the animal health situation in the country is an important factor in the evaluation of Vet. Services. Disease control cannot be done properly without accurate and reliable epidemiologic data

33 Transparency & honesty
Once a country’s epidemiological data loses credibility, especially for trade, it is difficult and time-consuming to recover.
