Abstract
Emerging infectious diseases affect the health of animal and human populations, but the impact goes beyond health as it extends to political, economic, social and environmental domains, as well as inter-state relations. Deeper understanding of these impacts aids public health authorities in their duties of protection and improvement of the health of their communities, promotion of healthy practices and research on disease, injury and threat prevention and mitigation. This empirical essay gathers insights from Cambodia, Hong Kong and Indonesia as they attempt to design and implement control and surveillance systems against avian influenza - an infectious disease.
