Signs of coefficients 𝐵 and 𝐶 as functions of exogenous reinfection rate of latent 𝛿 and exogenous reinfection rate of recovered 𝜂 for 𝑅₀⩾1. The parameter 𝛽 has the values: (a) 𝛽=𝛽_𝑅0=0.0001450317354, (b) 𝛽=0.0002450317354, (c) 𝛽=0.0003450317354, and (d) 𝛽=0.001145031735.

(a) 𝑅₀=1

(b) 𝑅₀=1.689504264

(c) 𝑅₀=2.379008527

(d) 𝑅₀=7.895042636
