Biosecurity Systems: Modeling Biological Threats from Emergence to Global Response

This book offers a way to look at biosecurity that considers many factors instead of just focusing on pathogens, helping us understand biological threats better. It looks at how the relationships between germs, their hosts, the environment, and human systems create complicated risks that can grow from small outbreaks to worldwide emergencies. The book combines epidemiology, systems biology, and security analysis to examine how diseases spread, interact with hosts, persist in the environment, and influence biological risk. A key point is that biological risk is influenced more by the connectivity of systems, the timing of events, and the speed of our response, rather than just the characteristics of the diseases themselves. The book highlights structural gaps in surveillance, detection, and governance that reduce prediction accuracy and delay response. Using a quantitative, scenario-based perspective, it addresses emerging risks shaped by technology, environmental change, and global interdependence, offering a foundation for improved preparedness and resilience.
