Simulation of the total infectious with parameters 1.03×r=0.9496, 1.5×α=0.1503, 1.5×g=0.7533, 1.5×ϕ=0.0750, 0.9×δ=0.5128, 0.99×ψ=0.0505, 0.7×β₁=3.1067, 0.7×β₂=0.2096 and 0.7×β₃=4.1063, when one parameter takes a specific value, others take the value of the first column in Table 3. Differently, we synthesize the effects of three contact rates β_i,i=1,2,3 into one contact rate β effect. ‘With all control’ means that we let all parameters specific values simultaneously. ‘Without control’ is the situation which we take no measures. We can find ψ has a mild effect on the total infected, with its line overlapping with ‘without control’ approximately
