Figure 2.

Relationship between strength of interaction and prevalence ratio for uniform interactions between influenza and SARS-CoV-2. The scenarios tested correspond to $\theta ={\theta }_1^{(I)}={\theta }_1^{(T)}={\theta }_2^{(T)}={\theta }_2^{(I)}$ (x-axis), for three different values of the average post-infectious period (1/δ = 1/δ₁ = 1/δ₂); other parameters were fixed to model the coupled dynamics of influenza and SARS-CoV-2 (cf. table 1). The dashed grey identity line depicts equality between the prevalence ratio and the true strength of interaction (PR = θ). The x- and y-axes are log-transformed. (Online version in colour.)
