Modeling Tuberculosis Contact Tracing and the Role of Social Cluster

We propose a discrete model to investigate the role of contact tracing program reducingthe new cases and prevalence of tuberculosis. We observe that the tuberculosis contact tracing program has no effect on the basic reproduction number R0 but the size of social cluster has. On the other hand a contact tracing program can speed up the process of TB elimination. We compute the partial rank correlation coefficient (PRCC), based on Latin hypercube sampling (LHS), to evaluate the effect of input parameters on the magnitude of the new cases and prevalence. The most influential parameters are identified and ranked.
