Description
Summary:Friedman & Aral use a social network approach to examine the spread of disease. Their article introduces some important network concepts & outlines how networks can affect behavior & infection probabilities. Risk-potential networks are defined as patterns of risk-potential linkages among a group of people, with risk-potential linkage being a tie between two people that can spread infection. For HIV infection, having sex & injecting drugs are risk-potential linkages. The article explains that egocentric networks only concern the direct linkages of a given person, & sociometric networks consist of a set of people & all linkages among them. Friedman & Aral then discuss the five papers in the special issue that demonstrate the benefits of network analysis. The article then discusses other issues in using networks to study & intervene in health-related matters not mentioned in the included articles. It is concluded that network research offers promise for improving health & responding to epidemics. 2 Figures, 21 References. J. Backman
