VIGILA is a flexible computer system designed for epidemiological surveillance of transmissible diseases. It aids in managing morbidity, mortality, and agent circulation data for early epidemic detection and control.

Area of Science:

  • Epidemiology
  • Public Health Informatics
  • Computer Science

Background:

  • Effective epidemiological surveillance requires rapid detection of unusual disease increases.
  • Existing systems may lack flexibility for diverse health organization levels.
  • Managing morbidity, mortality, and agent circulation data is crucial for disease control.

Purpose of the Study:

  • To develop a flexible computer system, VIGILA, for transmissible disease surveillance.
  • To enable efficient management and analysis of epidemiological data at national, provincial, and municipal levels.
  • To support early detection and control of disease outbreaks.

Main Methods:

  • Development of the VIGILA system with features for data storage, validation, and statistical analysis.

  • Implementation of a modified R. Serfling's model for endemic forecasting and alert threshold calculation.
  • Inclusion of data on morbidity, mortality, laboratory samples, and population demographics for rate calculations.
  • Geographical representation of the epidemiological situation using risk factor mapping.

    • Main Results:

    • VIGILA allows flexible data management and statistical analysis of transmissible disease information.
    • The system generates endemic forecasts and calculates alert thresholds using a modified Serfling model.
    • It facilitates the calculation of cumulative cases, rates, and comparisons with historical data.
    • VIGILA provides geographical risk assessments and enables early epidemic detection for timely intervention.

    Conclusions:

    • VIGILA is a versatile and adaptable system for epidemiological surveillance of transmissible diseases.
    • Its features support data-driven decision-making for public health interventions.
    • The system enhances the capacity for early warning and response to disease outbreaks.
