Approximately a quarter of the global population harbours the TB bacteria and another eight to nine million new cases of tuberculosis emerge every year [ 5 ]. To the best of our knowledge, this result has not been observed in previous TB modelling studies. The equilibria of the model are found by setting the rates of all variables in the left-hand side of Eq 1 to zero.

Backward bifurcation and hysteresis in models of recurrent tuberculosis

Hence, with relatively low immunity amongst recovered individuals [ 13 ] backward bifurcation can occur despite the fact that the Lipsitch and Murray [ 18 ] prediction would literally predict otherwise.

R 0 may be determined using the next generation operator method see [ smua ] as shown in S1 Appendixwhere it is sma that: No reinfection path Ai. Hence, this already suggests that R 0 alone is unable to completely quantify some key dynamical features of the TB epidemic, and is in fact the first sign that a backward bifurcation might be involved.

In the absence of recurrent TB due to reinfection i. In the more recent literature, numerous studies have pointed out that initial infection may not confer protection against exogenous reinfection especially in high-risk populations [ 5051 ].

Although, there are numerous TB models that have attempted to include the recurrent TB pathway for instance see [ 22 — 27 ]none have explored its role in the formation of backward bifurcation. The extra infectives from the latter compartment will tend to increase TB prevalence and thus widen the bifurcation curves. Conversely, when R 0 is above unity an epidemic may trigger and long-term disease persistence is feasible.

This characteristic is indicative of forward bifurcation as seen in Fig 7.
