Outline • Background of disease and infection control • General overview of project(s) • Data • Examples of reports • Conclusions and further steps
1. Rationale • Important swine disease • Complex viral infection of swine • Multiple genotypes • Complex infection control • Some success with herd and system-level elimination • Idea of regional elimination and control1 1 Corzoet al, 2010. Virus Research
1. Developments in Canada and Ontario • Good response from producers and practitioners • First study • Niagara region PRRS ARC&E1 in 2010/2011 • 76/78 known sites • 13,000 sows + 85,000 growing pig spaces • From initial 40% herd prevalence to 20% herd prevalence today • More enthusiasm for participation • Ontario (350 sites within 5 projects and growing) • Alberta • Quebec (~10% of the industry under regional programs) 1 PRRS ARC&E = PRRS Area Regional Control and Elimination
2. Multiple processes in ARC&E Basic information Detailed information Standardization Spreadsheets and EpiData Fluid Surveys Direct data entry SQL Server 2008 Static mapping Interactive mapping
2. Objective • Develop an easily accessible system that will gather necessary data in a standardized form, summarize the data, and communicate information to “those who need to know” • Purpose: • Primary: disease control • Secondary: disease surveillance, epidemiological research • Data = biosecurity, network, diagnostics, spatial • Those who need to know = producers, veterinary practitioners, project coordinators, industry representatives
3. Data • Participation agreements • Premises identifications (OP marketing board) • Location • Ownerships and contacts • Pig owner • Premises owner • Contractor • Veterinarians and Clinics • Demographics • Biosecurity (risk factors) • Willingness to control Enrollment Form
3. Data con’d • Major networks • Truckers • Gilt suppliers • Feed suppliers • Sources of pigs • Any change in the system ownership, management or suppliers Enrollment Form Change of Information Form
3. Diagnostic data Coordinator PRRSV Status Can change based on status of other sites Results of diagnostic testing Clinical triggers PRRSV genotype status Can change only based on status of this site PRRS TABLE Veterinary notification Upstream information Vaccinations Change of information
3. Registration and user roles • Online registration into the system • Different cross-classified roles • Access to information • Producer • Veterinarian • Coordinator/Researcher • Administrator • Geographical: PRRS ARC&E regions • Different regions
5. Further steps • Further development and testing of user interface • User interface tools • Development of user-specific reports • Directly from the database • Monitoring virulence • Adding sequence information
5. Conclusions and lessons learned • Bottom-up approach (producers and veterinarians) • Epidemiological and diagnostic information • Management of user registration and user roles very important • Different projects – different end users • Need to accommodate and manage data of different accuracy • Substantially different • Keeping information up-to-date
