Fig. 4From: Epidemic cycling in a multi-strain SIRS epidemic network modelExamples of incidence time series under eight different levels of cross-immunity. Other parameters: κ = 4, λ = 10, σ = 0.005, and μ = 0.0005. Two strains are represented by different lines. In graph (f) ψ = 1, two strains completely synchronize so that their incidences overlapBack to article page
