10 Organization of African Unity/Inter African Bureau for Animal ResourcesPan African Programme for the Control of Epizootics (PACE) Slide No.9 CONTROL AND/OR ERADICATION 3 options: Option 1: Stamping out - Destruction of infected and at-risk (depending on likelihood that birds are infected) poultry. - As quickly as possible (within 24 h) - Samples taken - Vaccination of workers applying culling. - Humane destruction - Accurate records

11 Organization of African Unity/Inter African Bureau for Animal ResourcesPan African Programme for the Control of Epizootics (PACE) Slide No.10 NATIONAL LEVEL Option 2: Modified stamping out using vaccination - - Destruction of infected poultry - USE OF VACCINATION: Reduces susceptibility to infection and decreases shedding therefore reduces the incidence of new cases and viral load in the environment. Tool to maximize bio-security. - Vaccination in response to an outbreak: ring vaccination or vaccination of designated high-risk poultry.

12 Organization of African Unity/Inter African Bureau for Animal ResourcesPan African Programme for the Control of Epizootics (PACE) Slide No.11 NATIONAL LEVEL Option 3: Blanket vaccination -Pre-emptive “baseline” vaccination of all part of a population of poultry may be used if the risk of infection is high and/or the consequences of infection are very serious. In addition to all 3 options:

13 Organization of African Unity/Inter African Bureau for Animal ResourcesPan African Programme for the Control of Epizootics (PACE) Slide No.12 NATIONAL LEVEL n EFFECTIVE SURVEILLANCE n BIOSECURITY: Bio-containment and bio-exclusion n CONTROL OF MOVEMENT OF BIRDS AND PRODUCTS - Movement of items from infected zones - Border controls n DISPOSAL OF CARCASSES AND POTENTIALLY INFECTIVE MATERIAL IN A BIOSECURE MANNER

14 Organization of African Unity/Inter African Bureau for Animal ResourcesPan African Programme for the Control of Epizootics (PACE) Slide No.13 REGIONAL LEVEL - Avail Emergency funds - International Cooperation - Harmonization and Coordination: sharing disease information

15 Organization of African Unity/Inter African Bureau for Animal ResourcesPan African Programme for the Control of Epizootics (PACE) Slide No.14 CRITERIA FOR CHOICE CHOICE OF OPTION: COUNTRY DECISION BASED ON: - Epidemiological situation: national and regional - Available resources: human, financial etc - AO relevant information

16 Organization of African Unity/Inter African Bureau for Animal ResourcesPan African Programme for the Control of Epizootics (PACE) Slide No AU/IBAR STRATEGY (contd) 2.2. Suggested strategy to address the current situation Preliminary Lessons learnt from the current situation - delay in laboratory confirmation - Difficulties in sending samples to reference laboratories - Difficulties to determine the source of infection - Absence of means to implement the modified stamping without vaccination strategy

17 Organization of African Unity/Inter African Bureau for Animal ResourcesPan African Programme for the Control of Epizootics (PACE) Slide No AU/IBAR STRATEGY (contd) Suggestions to countries in West Africa - Stamping out: country with 50 million 1% of chicken population and 3 $/head: 1,500,000 $ 5% of chicken population and 3 $/head: 7,500,000 $ 10%: 15,000,000 $ n + cost of other measures n - Modified stamping out: Half to be destroyed and half to be vaccinated $ 3,750,000 $ 7,500,000 $ +/- cost of vaccination and + cost of other measures

18 Organization of African Unity/Inter African Bureau for Animal ResourcesPan African Programme for the Control of Epizootics (PACE) Slide No AU/IBAR STRATEGY (contd) -Vaccination (1 year) In modified stamping out: half to be vaccinated 0.5 % heads X 0.1 $/head X 2 X 2: 100,000 $ 2.5 %: 500,000 $ 5 %: 1,000,000 $ + personnel, vaccine storage and transport etc Blanket vaccination: 80 %: 16,000,000 $ + personnel, vaccine storage and transport etc

19 Organization of African Unity/Inter African Bureau for Animal ResourcesPan African Programme for the Control of Epizootics (PACE) Slide No CONCLUSION n Best choice: seems to be modified stamping out. n Consider all the conditions for its efficient implementation n Vaccinations: Very Costly but could be used in some circumstances. n Suggestion for commercial farms: Kill all chickens, store and sell and then apply sanitary vacuum before re-stocking.
