A deterministic framework for epidemic dynamics with abrupt intervention: Indicator-based switching and phase-dependent thresholds

Mathematical models of epidemiology frequently assume time-invariant parameters, failing to capture the abrupt systemic shifts triggered by delayed medical interventions. In this study, we formulate a deterministic Susceptible-Infectious-Recovered (SIR) framework incorporating an abrupt, time-triggered intervention m...
