Part VII: A Double-Edged Sword: Contagion and Containment

Networks have a dark side. They speed the flow of communication and commerce but also can be conduits for diseases, terrorism, computer viruses, and other threats. The final section of the book explores the dark side of networks and strategies for addressing these challenges. In Chapter 26, Boaz Ganor takes up the challenge of terrorist networks and considers how antiterrorist agencies have had to build their own networks in response. In Chapter 27, J. Shin Teh and Harvey Rubin examine the role of global networks of air travel and connections in the spread of infectious diseases, and how these complex networks require a collaborative international solution. In Chapter 28, Jere R. Behrman, Hans-Peter Kohler, and Susan Cotts Watkins explore the power of informal social networks in preventing HIV infection in Kenya and Malawi, showing that the context and density of networks affect outcomes.
