Modelling the Periodic Outbreak of Measles in Mainland China

Figure 3

Change of the basic reproduction number with varying values of rate k. (a) We decrease baseline transmission rate (represented by (1 − k)a) and increase coverage rate of children under 2 years old and recovery rate (represented by (1 + k) p_c, (1 + k)0, 0 ≤ k) ≤ 0.04). (b) We decrease parameters related to asymptomatic infection (represented by (1 − k)ξ, (1 − k)η, (1 − k)θ, 0 ≤ k) ≤ 0.9).
