Expert review evaluates mechanistic modeling in viral transmission, demonstrating that scenario planning guides policy despite inherent predictive uncertainty.

Key Points

To clarify the primary capabilities, inherent boundaries, and appropriate policy applications of mechanistic epidemiologic models during the COVID-19 pandemic.
Analyzed the structural assumptions and theoretical foundations of mechanistic models used to simulate infectious disease transmission.
Examined how nonlinear transmission dynamics, variable human behaviors, and parameter uncertainties constrain predictive precision.
Mechanistic models serve primarily as scenario-testing tools to compare relative policy interventions rather than as long-term deterministic forecasting devices.
Model accuracy degrades quickly over extended horizons due to behavioral feedback loops and evolving biological parameters, necessitating continuous updating with empirical data.
