Comparison between calculated values of the CER and TER for the stochastic SIR model with seasonal transmission, for a range of values of <i>β</i>₁.

A. The CER (obtained using equation <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1012364#pcbi.1012364.e094" target="_blank">(8)</a> in the main text; blue line) and the TER (obtained by solving system of equations <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1012364#pcbi.1012364.e132" target="_blank">(11)</a> in the main text numerically; orange line) when <i>β</i>₀ = 10, <i>β</i>₁ = 0 and <i>γ</i> = 4 . 9 month^-1. B. Analogous results to panel A, but with <i>β</i>₁ = 3. C. Analogous results to panel A, but with <i>β</i>₁ = 6. D. Analogous results to panel A, but with <i>β</i>₁ = 9. In all panels, a threshold of <i>M</i> = 100 and a time step of <i>Δt</i> = 0.00033 months was used when computing the TER. The overall population size was assumed to be individuals. Insets show <i>R</i>₀ ( <i>t</i> ) = <i>β</i> ( <i>t</i> ) / <i>γ</i> ( <i>t</i> ) as a function of <i>t</i>. (PDF)
