  The effect of stigmatization is hindering the control of diseases. Especially
in the case of exogenous reinfection, this effect can play a massive role. We
develop in this paper, based on a tuberculosis model of Feng et.al. a model
with exogenous reinfection and stigmatization. As in the base model, in
presence of exogenous reinfection there exists multiple endemic equilibria. We
solve an optimal control problem for a case scenario and show that both types
of measures, those fighting stigmatization but also direct disease control have
to be invoked.
