1 Lumpy skin disease situation in Bulgaria Dramatic evolution & lessons learnt

2 Measures under Orders РД / and / In the regions bordering Turkey and Greece: Enforced epidemiological preparedness Weekly clinical examinations in all cattle herds Ban for animal markets Enforced controls on the identification of all cattle and update in National electron database Regional and municipal epizootic commissions Information for mares, farmers and all stakeholders about clinical signs, biosecurity measures and their obligations in case of suspicions Enforced controls on animal movements and biosecurity measures

4 The LSD situation in Bulgaria Date of first outbreak: 13 Apr 2016 Date of last outbreak: 01 Aug outbreaks confirmed 17 regions affected 2814 bovines in the affected herds 366 bovines with clinical signs

5 LSD outbreaks and bovine number by territory

6 The LSD situation in Bulgaria Date of first outbreak: 13 Apr 2016 Date of last outbreak: 01 Aug outbreaks confirmed 17 regions affected 2814 bovines in the affected herds 366 bovines with clinical signs

7 LSD cases in milk and meat production herds

8 Density of the LSD outbreaks 17 affected regions (out of 28) in total Number of LSD outrbeaks confirmed per regions Number of LSD outrbeaks confirmed per regions Shumen Gabrovo Yambol Haskovo St.Zagora Sofia city Smolyan Plovdiv Pernik Pazardzhik Montana Lovech Kyustendil Kurdzhali Vratsa V.Turnovo Blagoevgrad

9 LSD outbreaks per size of the herds Small herds (up to 10 animals ) with low biosecurity are mainly affected 19% 27% 6% 2% 46% up 1 cattle in the farm 2 to 10 cattle in the farm 11 to 40 cattle in the farm cattle in the farm more than 100

10 Updated Outbreak Assessment Lumpy Skin Disease in South East Europe 29 th April 2016 Ref: VITT/1200 LSD in South East Europe

11 Control measures based on: Council Directive 92/119/EEC of 17 December 1992 introducing general Community measures for the control of certain animal diseases and specific measures relating to swine vesicular disease; Commission Implementing Decision (EU) 2016/645 of 22 April 2016 concerning certain protective measures against Lumpy skin disease in Bulgaria; Commission Implementing Decision (EU) 2016/1183 of 14 July 2016 approving the emergency vaccination programme against lumpy skin disease of bovine animals in Bulgaria and amending the Annex to Implementing Decision (EU) 2016/645; National legislation

12 Vaccination

13 Vector control and desinsectisation over vector biotopes (along main rivers, valley and paddy fields). spraying outbreaks areas and Danube area

14 Surveillance in vectors LSD virus found (PCR positive) in: Flies: Tabanus spodopterus - females Ticks: Hyalomma marginatum - females Rhipicephalus bursa - males + females

15 Surveillance in wildlife No studies if LSDV affects European wildlife LSD detected in saliva from affected cattle with generalized form of the disease, while blood was already negative Non-invasive sampling with salt lick type of baits was performed to collect saliva from red deer and follow deer and to be tested for LSD The NI sampling was performed in area where the disease was present in domestic cattle Results: no evidence that LSDV affects red and follow deer. Non invasive surveillance for LSD works well for cattle. Surveillance in wildlife is being continued

16 Key challenges and problems faced New disease and lack of experience; Vaccine delivery tender procedures; Laboratory capacity; Trade restrictions, bovine transit problems; The social factor;

17 Key challenges and problems faced 2 For a first time not a money problem!!! New disease and lack of vaccine producers Many countries involved in same time EC vaccine bank Tender procedures written from lawyers and accountants problems in emergency!!! Quick response to many outbreaks at the same time Vaccine delivery tender procedures Outbreaks after vaccination Laboratory capacity for distinguishing (DIVA not present)

18 New Decision voted at PAFF, 14 Sept Movements allowed under conditions
