Figures & data
Figure 1. A phase portrait of S vs I for the cholera model Equation(16)–(19). The total population is N=10, 000, and the initial condition is I(0)=1000, S(0)=9000 and R(0)=B(0)=0. The curve converges to the endemic equilibrium at S* ≈ 1510, I* ≈ 2.68. Similar pattern is observed for various different initial conditions.
Figure 2. A phase portrait of S vs I for the cholera model (49)–(53). The total population is N=10, 000, and the initial condition is I(0)=1000, S(0)=9000, and R(0)=B H (0)=B H(0)=0. The curve converges to the endemic equilibrium at S* ≈ 7666 and I* ≈ 0.92. Similar pattern is observed for various different initial conditions.
