As the nation and the world continue to grapple with H1N1, and while delivery of the vaccine in the United States faces delays, school closures are one policy tool under consideration to slow spread of the pandemic. Ross Hammond, co-author of a recent report that quantified the economic effects of school closures, and Fred Barbash, Politico senior editor, took questions in a live web chat about the implications and potential costs of this approach.

Policymakers are looking at school closures to contain the spread of an H1N1 influenza outbreak. 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.

Obesity has grown rapidly into a major public health challenge in the United States and worldwide. The Centers for Disease Control and Prevention has said that as many as one-third of Americans are obese. Ross Hammond explains how techniques from the field of complexity science can inform both scientific study of obesity and effective policies to combat it.

With cases of swine flu rising in the United States and around the world, health officials are taking action to contain the spread and severity of the disease. Brookings Fellow Ross Hammond discussed the artificial society models he has helped develop that can aid professionals in better understanding how to prepare for and react to epidemics.

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.

In his latest working paper, CSED Fellow Ross A. Hammond says that obesity is a substantial and growing public health crisis worldwide. 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.
