    Study Notes

    Information

    • Information is processed data that provides context and meaning.
    • Data is simply facts and figures, while information is processed data with meaning.
    • Information comes from many sources like books, websites, observations, and experiments.

    Information Use

    • Information must be:
      • Managed: This means ensuring its quality, controlling access, and keeping it organized.
      • Analyzed: This means turning the information into something understandable through interpretation and processing.
      • Acted upon: This means using the information to make decisions and take action.

    Information Gathering

    • Veterinary Services require effective systems to gather relevant information from the field.
    • This information must be processed into a form that national policy makers and field staff can use.
    • Web-based animal health information systems allow for near-instantaneous dissemination of information.
    • Increased communication and connectivity mean there are more sources of information on animal diseases than ever before.

    Animal Health Information Systems

    • Animal health information systems gather, collate, and analyze data to provide meaningful information.
    • National systems handle information about the health of livestock within a country.
    • Regional systems are designed for specific areas, such as the EU’s Animal Diseases Information System (ADIS) and the ASEAN Regional Animal Health Information System (ARAHIS).
    • Global systems, such as the OIE’s World Animal Health Information System (WAHIS), FAO’s EMPRES-i system, and ProMED, provide information on a wider scale.
    • Some animal health information systems are password-protected and not publicly accessible.

    Purposes of Animal Health Information Systems

    • Provide comprehensive information to decision makers on disease, control measures, and their consequences.
    • Share information within and between countries (early warning system).
    • Monitor disease occurrence and control programs.
    • Estimate vaccination coverage.
    • Provide information required to meet international disease reporting needs.
    • Support declarations of disease status for trading purposes.
    • Identify unusual disease events or emerging diseases.
    • Highlight shortfalls/gaps in surveillance.

    Transboundary Animal Disease Information System (TADinfo)

    • TADinfo was developed by the FAO and is designed to be customizable for each country.
    • It imports geographical information and allows data transfer to regional and global animal health information systems.
    • The new TADinfo has innovations that improve upon the first generation.

    Geographical Information System (GIS)

    • A computerized database management system used for capturing, storing, analyzing, and displaying spatially referenced data.
    • Consists of four main components:
      • Input
      • Storage
      • Manipulation
      • Output
    • Used as tools for analysis, modeling, and decision-making.
    • Disadvantages:
      • Expensive
      • Requires a vast amount of data input
      • GIS layers can lead to costly mistakes
      • Initiating and implementing GIS can be challenging
      • Large amount of data can cause problems when analyzing due to complexity
    • Data requires complex overlay operations that may require specialized training for personnel.

    Visual Display of Spatial Phenomena

    • The visual display of spatial phenomena offers a powerful descriptive analytical tool.
    • Example: The distribution of different strains of Mycobacterium bovis in a wild animal population was used to understand disease transmission paths.
    • Example: GIS maps helped to visualize the distribution of brown ear ticks in southern Africa and compare the prevalence of Rhipicephalus appendiculatus with East Coast Fever occurrence.

    Spatial Analysis

    • Involves:
      • Preparing an appropriate model.
      • Proper visualization.
      • Exploratory data analysis.
    • Ranges from simple map overlay to statistical models.
    • Helps interpret and predict the movement of populations and inanimate objects.
    • Example: GIS maps the movement of animals between wild and domestic areas to identify high-risk areas for disease transmission.

    Types of Spatial Data

    • Point Patterns: Analysis of point patterns helps understand spatial clustering related to disease transmission.
    • Geostatistical Data: Statistical methodology used to assess if a point pattern is regular, random, or clustered.
    • Lattice Data: Represents a surface using a grid of regularly spaced sample points with a constant sampling distance.

    Applications of GIS in Veterinary Medicine

    • GIS has broad applications in the veterinary field, including:
      • Outbreak notification.
      • Disease prevention and eradication.
      • Disease surveillance.
      • Understanding disease dynamics and spreading patterns.
      • Correlation of disease trends with climate.
      • GIS was first used in veterinary medicine in 1994 to address the Foot and Mouth Disease epidemic.

    GIS Capabilities

    • Maps epidemiological information like morbidity, mortality, prevalence, incidence, and geographic disease distribution.
    • Supports the veterinary sector in analyzing relationships between locations, the environment, and disease patterns.
    • Helps assess the risk and distribution of diseases across countries.
    • Used for various GIS operations:
      • Buffer generation
      • Overlay operation
      • Neighborhood analysis
      • Spatial analysis

    Overlay Operations

    • Combine information from different vector files into a new, more tailored file.
    • Change both the spatial and attribute levels of the data.

    Buffer Generation

    • Calculates the distance from each cell to its nearest source.
    • Used for applications like:
      • Finding the nearest hospital.
      • Calculating distances from outbreak sites.
      • Determining distances to major roads.

    GIS Software

    • Two commonly used GIS software programs in veterinary medicine are:
      • Quantum GIS (QGIS)
      • ArcGIS
    • GIS outputs can be presented as maps, tables, diagrams, and other forms.

    Data Sources of GIS

    • Data for GIS can come from:
      • Paper Maps: Maps are one of the most traditional sources of GIS data.
      • Remote Sensing: Uses sensors on satellites or aircraft to gather data about the earth's surface.
      • Global Positioning System (GPS): Uses satellite signals to determine locations, directions, and time.

    Application of GIS in Animal Disease Surveillance

    • GIS is a valuable tool in disease monitoring and surveillance programs.
    • It helps visualize disease foci, monitor newly infected or re-infected areas, identify populations at risk, target interventions, and monitor eradication efforts.
