  1. ZIMBABWE’S EXPERIENCES H5N2 IN OSTRICHES

  2. The Outbreak? • Matabeleland North Province • Two ostrich properties • Mimosa and Dollar Bubi • during routine surveillance in November 2005 • Antibodies first detected in slaughter stock and later in all classes • No clinical signs, no deaths • Combined population of 16 000 ostriches • Outgrower system practiced

  3. Response • Poultry and ostrich farmers notified • All ostrich farms put under quarantine and screened for AI antibodies • Slaughter of ostriches suspended • Self-imposed ban on the export of all ostrich and poultry products • Increased serosurveillance on all farms • Sera sent to RSA for determination of N type • Determined as H5N2 • Communications with SADC, OIE and trading partners

  4. Surveillance Background • Zimbabwe has been routinely screening for AI for the last 6 years • All Newcastle Disease cases are tested for AI • 6% of all ostrich slaughter stock tested • 15 % of all ostriches per farm were being tested

  5. Post outbreak surveillance • All properties were asked to submit 60 blood samples per epidemiological unit per month for testing. • Poultry industry collected samples from properties adjacent to their properties if any as well as from their outgrowers if any • DVS has been collecting samples from small holder farmers. • A more comprehensive sampling plan has been made but has yet to be implemented.

  6. Diagnostics • The Central Veterinary Laboratory was involved in the screening of all samples using the HAI test and more recently the ELISA. • They stepped up their capacity to 2000 samples per day using the HAI • Lab is only able to determine H and not N • Zimvet, a private Laboratory was authorized to test on behalf of the CVL • Proficiency testing between the two Labs-Quality assurance.

  7. Compartmentalization • Zimbabwe decided to follow the compartmentalization route to allow exports • A checklist for farm inspections was designed and used every month • Emphasis on bioseurity of properties • Poultry farms are submitting 60 blood samples per month from each epi-unit • Four properties registered as AI free compartments so far in accordance with OIE code, Chapter 1.3.5 • The properties have been authorized to export ONLY Hatching and Table eggs and Day old chicks.

  8. AI taskforce • Was set up prior to the outbreak • Co-chaired by Ministry of Health and Child Welfare and Veterinary Services • Multi-stakeholder assn, (WHO, FAO, Wildlife Management & Parks, Ministries of Transport & Communications and Home Affairs, ZIMRA, Bird Groups) • Meets once monthly • At district level, zoonotic subcommittees made up of MOHCW and Veterinary services meet monthly.

  9. Functions of taskfoce • Develop the contingency plans • a draft has been produced Review • Current world situation on AI & how it could enter Zimbabwe • Current and future surveillance • Lab diagnostic capacity, international collaboration • Control of possible outbreaks • Zoonotic implications

  10. Awareness Programs Through • Electronic and print media • Meetings with livestock producers associations • Pamphlets for residents of wetlands • Communiqués to Provincial Governors-Provincial Admin- District Admin-People • Police • Cabinet via Secretaries and Ministers

  11. Regional cooperation • Learning visit to South Africa • Government and private Veterinarians • Visit by Botswana • Words of support from the region.
