This chapter presents both monetary and non-monetary methods of measuring burden of disease caused by
Toxocaraspp. and the cost benefits of control. In addition, this chapter discusses morbidity rates, decision tree analyses, avoidable losses, modelling uncertainty, and economics of animal health. Rather than embarking on an economic analysis of toxocariasis, this chapter has attempted to provide ideas as to how such an economic analysis might be undertaken and has described different measures (such as financial loss or disability adjusted life years) that can be used to measure societal burden of disease and how Monte-Carlo techniques can be used to model uncertainty.
