This seminar focuses on the OIE's World Animal Health Information System (WAHIS) and the obligations of member countries to report diseases and infections. It also discusses the new forms for immediate notification and follow-up for terrestrial and aquatic animals.

Seminar on the Dialogue and Common Activities between the OIE Member Countries of the European Union and the other Member Countries of the OIE Regional Commission for Europe Ankara, Turkey, 21-22 November 2005
Dr Dewan SIBARTIE OIE, Central Bureau, Head of the Scientific and Technical Department 21-22 November 2005 The OIE’s World Animal Health Information System‘WAHIS’ .
New World Animal Health Information System (WAHIS) • One OIE’s mission : To ensure transparency in the world animal disease situation including zoonosis • Obligations of Member countries • To report diseases, infections and other epidemilogical events • To the OIE Central Bureau • According to the conditions described in the chapter on notification and epidemiological information Chapter 1.1.2 of the Terrestrial Animal Health Code for terrestrial animal diseases; Chapter 1.2.1 of the Aquatic Animal Health Code for aquatic animal diseases.
New World Animal Health Information System (WAHIS) • Weekly reports: Follow-up to the immediate notification to inform on progress of the epidemiological situation • Final report : - if the outbreaks are ended - if the situation becomes endemic => six-monthly report • To report regularly on OIE-listed diseases at least once each six months • Annual questionnaire • New guiding manuals and new forms • New World Animal Health Information System that allows to register these different kind of reports
New World Animal Health Information System (WAHIS) • The new obligations clearly address the concept of infection without necessarily having clinical expression of the disease • Previous obligations did not take clearly into account changes of epidemiological situations of prevalent diseases within a country or a zone of a country (e.g. change in the behavior of a disease such a new host species becoming susceptible to the disease, etc.).
New World Animal Health Information System (WAHIS) • The new obligations better address the problem of emerging diseases, including zoonotic emerging diseases and go further more into a new concept which is to report on an emerging event, even if the etiological agent is not yet identified
Terrestrial animals - reasons for immediate notification • Which reasons for immediate notification ? • The first occurrence of an OIE-listed disease or infection in a country or zone/compartment; • The re-occurrence of a listed disease or infection in a country or zone/ compartment following a report by the Delegate of the Member Country declaring the previous outbreak(s) eradicated; • the first occurrence of a new strain of a pathogen of a listed disease in a country or zone/compartment;
Terrestrial animals - reasons for immediate notification • Which reasons for immediate notification ? • a sudden and unexpected increase in morbidity or mortality caused by an existing listed disease; • an emerging disease with significant morbidity/mortality or zoonotic potential; • 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.

Aquatic animals - reasons for immediate notification • Which reasons for immediate notification ? • for diseases listed by the OIE, - the first occurrence or re-occurrence of a disease in a country or zone of the country, if the country or zone of the country was previously considered to be free of that particular disease; - if the disease has occurred in a new host species; - if the disease has occurred with a new pathogen strain or in a new disease manifestation;
Aquatic animals - reasons for immediate notification • Which reasons for immediate notification ? • for diseases listed by the OIE, - if there is potential for international spread of the disease; - if the disease has newly recognised zoonotic potential; • for diseases not listed by the OIE, if there is a case of an emerging disease or pathogenic agent should there be findings that are of epidemiological significance to other countries.

Six-monthly report on the absence or presence of OIE listed diseases • Part 1: Qualitative information • Disease occurence, • Control, prophylaxis and prevention measures • Indication of the type of report to be used to notify diseases or infections present in the country (=> part 2) IF THE DISEASE/INFECTION IS ABSENT or NO INFORMATION AVAILABLE => it is not necessary to indicate the type of report to be used IF A DISEASE/INFECTION IS PRESENT or SUSPECTED => you have to indicate only one type of report to be used
Six-monthly report on the presence of OIE listed diseases • Part 2: Quantative information • Template 1 (recommended): By First Administrative Division and by Month • Template 2: For the whole Country and by Month • Template 3: By First Administrative Division and for the six months period • Template 4: For the whole Country and for the six months period TEMPLATE 1 IS RECOMMENDED FOR DISEASES WHICH ARE NOTIFIABLE IN THE COUNTRY
FAO-WHO-OIE Annual Questionnaire • New form in January 2006 • For non OIE listed diseases for OIE member Countries • For OIE and non OIE listed diseases for other Countries • Qualitative information (disease occurrence), • To notify diseases present in the country: template for the whole Country for the six months period • Livestock population (by first administrative division) • Human cases and deaths for OIE listed zoonotic diseases • Veterinarians and animal health technicians • National reference laboratories • Production of vaccines
FAO-WHO-OIE Annual Questionnaire – draft for 2005 Part « non OIE listed diseases » - draft
Data for Livestock population by first administrative unit – draft for 2005

New World Animal Health Information System (WAHIS) • The new World Animal Health Information System allows to register all the different kinds of report – will be lauched in october 2005 • The system uses maps and geographic coordinates for the outbreaks • An access (login, password) will be available to each Delegate • During the first access, the Delegate will check * the choice of the administrative unit as the first administrative unit * the list of the first administrative units * the map used for his/her country with the first administrative unit
New World Animal Health Information System (WAHIS) • The Delegate can register the agents the Delegate nominates for * notifying diseases or infections for Terrestrial or Aquatic animals - for the immediate notification and follow-up report - for the six-monthly report * the annual questionnaire • Each nominee registered will receive an access to WAHIS • For a better management of the reports, if the report are sent by a Delegate’s representative, it is better to give him/her an access
New World Animal Health Information System (WAHIS) • For each kind of report, the new World Animal Health Information System allows the Delegate or the nominee to save a draft, to print the report, to save the report on their computer and to transmit the report to the OIE • The Delegate or the nominee can edit existing reports • For the six-monthly report, the system will agregate existing data for the refered period for the diseases which have been notified • The six-monthly report can be made in several steps
Decision Tree NO YES NO • 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? AND/OR • Does the disease exhibit significant morbidity at the level of a country or zone? YES YES NO EXCLUDE INCLUDE INCLUDE EXCLUDE • INTERNATIONAL SPREAD • Has international spread been proven on three or more occasions? OR • Are more than three 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 three countries with susceptible populations are reporting absence of the disease? EMERGING (A newly recognised pathogen or known pathogen behaving differently) Is there rapid spread and/or apparent zoonotic properties? NO
