    Area of Science:

    • Epidemiology
    • Mathematical Biology
    • Virology

    Background:

    • Existing research on virus competition primarily relies on simulation studies.
    • Understanding the dynamics of interfering virus populations is crucial for public health.

    Purpose of the Study:

    • To develop and analyze an analytical mathematical model for the competition between two interfering virus populations in a community.
    • To identify equilibrium points and assess their stability.

    Main Methods:

    • Formulation of a mathematical model comprising eight coupled differential equations.
    • Analysis of the model to determine equilibrium points.
    • Application of stability criteria to evaluate the local stability of equilibrium points.

    Main Results:

    • The model features up to four distinct equilibrium points.
    • Criteria for the local stability of these equilibrium points have been established.

    Conclusions:

    • The analytical model provides a framework for understanding virus population dynamics and interference.
    • The stability analysis offers insights into the long-term behavior of competing virus strains.
