As the growing worldwide human population becomes more mobile and urbanized, there is a constantly increasing risk that infectious disease epidemics and their associated threats may reach global proportions. This is not just the case for human beings : endemic and production diseases are often overlooked, although they exert serious threats to animal welfare in farms and conservation of wild species. The consequences of climate change are added to these effects of globalisation, perturbing the ecosystem equilibria even further. New advances in science and medicine help us gain ground against certain infectious diseases, yet new infections that spread rapidly into the animal or human populations continue to emerge and occasionally reach pandemic proportions, causing significant casualties and economic costs. Disease transmission is strongly influenced by group or population contact network but the manner in which animals, including humans, interact evolves according to strength of ecological pressures as well. What is needed, therefore, is an analysis of disease dynamics that does not ignore the influence of a) social networks and b) ecological pressures (individual psychosocial stress and hormonal status). This is the analysis I propose in this project by studying several species, from insects to primates, and by modelling the influence of social networks on disease transmission using multi-agent based models.
