    Area of Science:

    • Epidemiology
    • Public Health
    • Mathematical Modeling

    Background:

    • Tuberculosis (TB) remains a significant global health challenge, particularly in regions with limited access to advanced computational resources.
    • Epidemiological analysis is crucial for understanding and controlling TB transmission dynamics.

    Purpose of the Study:

    • To develop and validate a simplified epidemiological model for estimating annual trends in tuberculosis.
    • To assess the model's utility in resource-limited settings by evaluating its approximation capabilities.

    Main Methods:

    • A straightforward epidemiological model was designed to calculate key TB indicators: prevalence, incidence, infection rates, mortality, and BCG vaccination coverage.
    • The model utilizes average parameter values, avoiding age-specific or cohort-specific data for broader applicability.

  • The model's accuracy was tested using comprehensive national data from Japan.

    • Main Results:

    • The model demonstrated satisfactory approximation capabilities within defined limits when applied to Japanese epidemiological data.
    • The calculations can be performed using basic tools like a desktop computer, calculator, or even by hand, enhancing accessibility.

    Conclusions:

    • This simplified model offers a viable solution for epidemiological analysis of tuberculosis in countries with limited computational infrastructure.
    • It provides a practical tool for monitoring TB trends and informing public health interventions globally.
