Mathematical Analysis of a General Two-Patch Model of Tuberculosis Disease with Lost Sight Individuals

Figure 4

Trajectories of infectious individuals in care center (a) and lost sight individuals (b) of (1) for different initial conditions when 𝛽₁=0.002 and 𝛽₂=0.003 (such that 𝑅¹₀=0.3691 and 𝑅²₀=0.4980). The infectious and lost sight classes disappear at the end and only susceptible classes persist when 𝑅₀<1. All other parameters are as in Table 1.
