Modelling the impact of HIV and ART on TB

Models of HIV and TB are well established and it is tempting to model the combination of HIV and TB by repeating a suitable TB model a number of times corresponding to the various states of HIV.

Fortunately, the time scales over which the two infections progress are very different, allowing us to greatly simplify the problem.
