Polynomial governing the survival function.
F(S) = βS2 − (β + μ + δ)S + μ is the RHS of (4) with parameter values β = 0.15 h−1, μ = 0.01 h−1 and δ = 0.01 h−1. The constants a and b satisfy and
. The value of a is equal to the probability that the infected macrophage eliminates the infection, rather than ruptures.
