Figure 4. — Sample phase portraits for Hida, Japan (a) damped oscillation using the autonomous model (3.1) with α = α_med = 96.5, δ = δ_med = 0.028; (b) sustained oscillation using the demographically forced model (3.2). The parameters μ = 16, R₀ = 3.05 for both. The infection parameter β is computed using equation (4.3).
