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


The OIE’s World Animal Health

Information System‘WAHIS’ .

Dr Dewan SIBARTIEOIE, Central Bureau,

Head of the Scientific and Technical Department

21-22 November 2005


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)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




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.).



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


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 notificationTerrestrial animals - 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.

Terrestrial animals - reasons for immediate notificationTerrestrial animals - reasons for immediate notification



Terrestrial animals – new forms for immediate notification and follow-upTerrestrial animals – new forms for immediate notification and follow-up






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 notificationAquatic animals - 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 diseasesSix-monthly report on the absence or presence of OIE listed diseases

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

Part 1: Qualitative information


Six-monthly report – disease occurenceSix-monthly report – disease occurence


Six-monthly report – Part 1: qualitative informationSix-monthly report – Part 1: qualitative information


Six-monthly report on the presence of OIE listed diseasesSix-monthly report on the presence of OIE listed diseases

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

Part 2: Quantative information

Data for Livestock population by first administrative unit – draft for 2005Data for Livestock population by first administrative unit – draft for 2005


















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



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



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 TreeDecision Tree

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?

INCLUDE

YES

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?

NO

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)

YES

INCLUDE

NO

EXCLUDE

EMERGING

(A newly recognised pathogen or known pathogen behaving differently) Is there rapid spread and/or apparent zoonotic properties?

NO
