Infectivity–persistence trade-offs in a monophasic pathogen decay model. a. Heatmap of the basic reproduction number \(\mathcal {R}_{0}\) of the monophasic decay disease model (Eq. (1)) as a function of persistence (τ) and infectivity (π). The line is the contour along which \(\mathcal {R}_{0}=2\). Here, N= 1000, γ= 0.1, κ= 8, ρ= 0.15, α= 0.001. The colored dots correspond to the colored lines in (b) and (c). b Fraction of the population infected for the values of pathogen persistence (τ) and infectivity (π) given by the dots in (a). Although all points have \(\mathcal {R}_{0}=2\), the epidemic dynamics vary significantly over the individual parameter values. c Pathogen decay curves in the absence of a system input illustrate the variation in the corresponding persistences (τ)
