ZIMBABWE’S EXPERIENCES H5N2 IN OSTRICHES
The Outbreak? Matabeleland North Province Two ostrich properties Mimosa and Dollar Bubi Mimosa and Dollar Bubi during routine surveillance in November 2005 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 ostriches Outgrower system practiced
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
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
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.
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.
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 The properties have been authorized to export ONLY Hatching and Table eggs and Day old chicks.
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.
