What are the links among the concepts of global public health, human health and animal welfare? The objective of this chapter is to discuss the relationship between public health and animal welfare issues, from the historical perspective of rabies control to the more recent challenges brought by the populations of different vertebrate species in urban environments. From what has been learned so far, considering both the efficiency and ethics of animal population control strategies, a change in paradigm is needed. The killing of animals for the sake of public health appears to be ineffective in the case of dogs and other animals studied; at this stage, proponents of this strategy should carry the burden of proof for its effectiveness based on knowledge of the population dynamics of the species involved. In some cases, urban animals can play a positive role in the control of zoonotic disease problems, especially if they receive health and welfare attention. Overall, zoonotic diseases, as well as health and welfare maintenance, occur within dynamic processes which cannot be dealt with by employing only short-term approaches.
