Decreasing the basic reproduction number decreases the exposed and infectious populations. The susceptible and recovered populations converge to larger and smaller endemic equilibrium values, and converges is slower. The steepest susceptible, exposed, infectious, and recovery curves correspond to the largest basic reproduction number of R0 = 10.0 with the maximum infectious population of Imax = 0.488 after 35 days and converge to an endemic equilibrium at S∞ = 0.0001 and R∞ = 0.9999. Latent period A = 5 days, infectious period C = 20 days, basic reproduction number R0 = C/B = 1.5, 1.7, 2.0, 2.4, 3.0, 5.0, 10.0, and initial exposed fraction E0 = 0.010.
