• The Costs of Containing H1N1

  Thu, 29 Oct 2009 13:39:10 GMT

In the first comprehensive U.S. study of the economic cost of school and daycare center closures, the Center on Social and Economic Dynamics at Brookings finds that closing all schools in the United States for four weeks could cost up to $47 billion and lead to a reduction of up to 17% in key health care personnel.

• Coupled Contagion Dynamics of Fear and Disease: Mathematical and Computational Explorations

  Mon, 15 Dec 2008 00:00:00 GMT

  
  In classical mathematical epidemiology, individuals do not adapt their contact behavior during epidemics. They do not endogenously engage, for example, in social distancing based on fear. Yet, adaptive behavior is well-documented in true epidemics. Joshua M. Epstein, Jon Parker, Derek Cummings, and Ross A. Hammond explore the effect of including such behavior in models of epidemic dynamics.

Many of its features—breadth of scale, diversity in actors, and multiplicity of mechanisms—are hallmarks of a complex adaptive system. Thus, according to Hammond, the lessons and tools of complexity science can help us better understand and combat the obesity epidemic.
