The accelerating and aggravating effects of the MEs. (a) The respective susceptibles in 𝑃₁ and 𝑃₂ regarding the simulation time steps with no MEs (𝜌=0) and merging intensity 𝜌=0.6. (b) The respective infectives in 𝑃₁ and 𝑃₂ with respect to the simulation time steps. (c) The aggregated susceptibles in 𝑃₁ and 𝑃₂ regarding the simulation time steps. (d) The aggregated infectives in 𝑃₁ and 𝑃₂ with respect to the simulation time steps. For both of the subpopulations, the population size 𝑁=1000000, 𝜏=0.0006, and 𝜑=0.2. All the results have been averaged from 100 simulations.
