West EurAsia FMD Control-Roadmap 2025, 4th Annual Regional Progress Review Meeting,
2-4th April 2013, Baku, Azerbaijan
Regulation relating to the FMD
• Directive for Control of FMD has been come into force., to breakthrough failing
points of the control measures, it has been initiated some work plans based on
requirements of the directive:
– Reconstruction TURKVET database
– Launching Sample Management System (SMS) under the TURKVET
– Some advanced measures on control of animal movement and trade • Registration and training of the animal dealers
• Transportation Animal Vehicles with effective bio-secure conditions based on Animal Wellfare Directive
• Movement of animals with ensured immunity level
– A interactive epidemiology training has been initiated for field vets by Şap Institute
Vaccination Strategy
• New vaccination strategy based on risk analysis has been initiated, since it has
been insufficient vaccine resource
Thrace Region Surveillance Program
To detect risk as possible early, more sensitive surveillance program has been launched in
Thrace Region by donation EC and expertise EuFMD Regular active surveillance (clinical examination)
Serosurveillance in the area where was identified as high risk per three month
Management advanced passive surveillance
Strategic FMD Control Plan
Analysing Socio-economic impact and risk
Surveillance has been designed as part of 2012 Autumn
Serosurveillace, aimed to analyse risk and socio-economic
impact.
Stage of collecting information has been finalized between
October2012-January1013
Aimed three basic analysis: – Impact of animal movement and animal trade pattern on disease dynamics and
role of milk collectors for disease transmission
– Impact of animal husbandry system on disease dynamic ; Role of SR for disease
transmission
– Impact of vaccination on control of the disease; between where vaccination apply
and species
Data cleaning and analysing have been continued,
results will be available soon
1. Vaccination
• New vaccination strategy based on risk analysis has been initiated, since it has been
insufficient vaccine resource, since it has been insufficient vaccine resource:
– Preventive campaign vaccination; acc.to risk analysis developing a vacc.program before each
campaign- where /which species vaccine apply
• LR; twice a year, vacc not apply as campaign in Anatolia;_In Thrace: LR: Twice a year/SR: once
– Ring Vaccination to response outbreak in Surveillance zone of outbreak
– Targeting vaccination for “Hotspot”; extending ring vaccination with specific serotype
2. Diagnosis and Genetic and Antigenic Characterization of Isolates
3. Epidemiological investigation
_ Active and passive surveillance
– Outbreak investigation and case study
– Serosurveillance; NSP Prevalence estimation in Anatolia/Disease detection in Thrace
4. Routine control measures in case of disease outbreak (biosecurity, restriction,
quarantine, sampling)
5. Control of animal movements and markets
6. Training vets and awareness activities
7. Vaccine effectiveness study to evalute vaccine used and application of vacc.

IDENTIFICATION OF CIRCULATING STRAIN
• FMD is endemic in Anatolia region in Turkey
• Current Circulating virus strains:
– Serotype O (O PanAsiaII),
– A (A Iran05) and
– Asia-1(Asia1/SINDH08)
• 1038 outbreaks recorded in Anatolia in 2012; 847 out of
them were serotyped by national reference lab, 90 were
untyped (virus not detected or only positive FMD), 101
were reported by clinical diagnosis.
• In 2013, up to 20th March, 131 outbreak were recorded
and serotyped

• A NSP Serosurveillance has been conducted in Anatolia region in Autumn 2012
• Objective: Estimation of NSP prevalence and risk analysis
• Species: LR (Cattle and W.Buffalo); SR(Sheep and goat)
• Sample Frame: 31 LR and 32 SR per epi unit, 64300 sera in 1027 epi units; collected sera: 61605
• Brief Results:
– Cumulative prevalence: 21,84%
– LR: 15,82%; SR: 23,78% (Sheep: 25,68%; Goat: 15,55%)
• Some initial remarks for results:
-High prevalence was estimated in east region
-Because of impact of Asia-1 outbreaks, higher prevalence was estimated in west area when compared with
1010 Surveiallance
-Higher prevalence was detected in Sheep rather than cattle and goat, but west area sheep prevalence also was
low than east area
-poor outbreak reporting was detected in the east;

Control-Roadmap 2025,
Regions included vaccination and allocated
vaccine for Spring 2013 Campaign
Regions have been included in Spring vaccination campaign in Turkey according to risk assessment:
• Campaign vaccination in Spring2013 : – Eagan (except Muğla),
– Marmara and Thrace regions
– Inner Anatolia (except three provinces; Aksaray, Karaman and Niğde)
– West and Middle Blacksea (Except four provinces; Zonguldak, Bartın, Karabük and Sinop)
– Two provinces in Mediterranean ; Burdur and Isparta)
– Two provinces in East Anatolia, Malatya and Elazığ
• Specific vaccination policy to response type A outbreaks using monovalent type A vaccine Extended ring vaccination has been used for type A outbreak- according to risk assessment all population in district in which occurred outbreak: It has been already initiated since January 2013
• Ring vaccination to reponse outbreak for serotype O and Asia, has been used In remained area of Turkey,
– when occurrence outbreak, livestock in protected and surveillance zone of outbreaks will be vaccinated as ring vaccination concept.
• ONLY LARGE RUMINANTS HAS BEEN INCLUDED FOR CAMPAIGN
ALLOCATED AMOUNT OF VACCINE -Campaign vaccination: 5 million trivalent (O Tur07, A Tur06 and Asia1Tur11)
-Specific type A monovalent vaccination: 1 million
-Ring vaccination: 400.000 trivalent

Control-Roadmap 2025,
– Are control measures reducing FMD impact?
Yes; Serosurveillance results indicated that where control measures has been applied
better, the disease impact has been reduced
It was observed that the number of outbreaks and affected animals were sharply
decreased after vaccination applied; for example, Asia-1 outbreaks occurred severely
in West area of Turkey in Spring 2012
Low incidence was detected in area which biosecurity and other control measures was
implemented much more better
– Are control measures moving towards FMD
elimination?
No, it has been not found any indication yet.
Critical assessment on if strategy is achieving the goal
Short term Plan for Surveillance and Control • Passive surveillance program will be continued including outbreak
investigation and typing as in routine
• Ear-tag system will be replaced with barcode system for LR and SR
• New sensitive surveillance system has been launched in Thrace,
activities will be started afterward this month
Longterm Plan for Surveillance and Control • In framework of National Veterinary Strategy Plan, a study for socio-
economic impact of FMD will be carried out in 2014
• As requirement of Directive “Standard of Storage, Delivery and Marketing
for Veterinary Medicine, Biological Substance and Vaccine”, some work
plan has been initiated:
– 2D Barcode System for veterinary medicine and vaccine will be implemented
– A vaccine storage rooms based on standard will be constructed in eac provincial
directorate
Plans related to FMD surveillance and control in the
short and long term.
