🌐 Dynamic Heterogeneity: Age-of-Infection Models and Distributed Delays ψ
The assumption of exponentially distributed waiting times in classic compartmental models leads to the mathematically convenient, but often biologically restrictive, memoryless property. Age-of-Infection Models (also known as Time-Since-Infection, TSI models) address this by explicitly incorporating the time spent in an infected state (τ) as a determinant of contagiousness, infectivity profile, and probability of recovery.
