Figure 5From: Assessing the effects of multiple infections and long latency in the dynamics of tuberculosisWe show the critical transmission coefficient β c q (a) and y ¯ q * (b) as a function of q. Using the values of the parameters given in Table 1, except γ = 0.008405 years-1, we have q c = 0, and y ¯ 0 * . In this set of values the backward bifurcation exists for all q.Back to article page
