Purpose The research community currently employs four very different versions of the social network concept: A social network is seen as a set of socially constructed role relations (e.g., friends, business partners), a set of interpersonal sentiments (e.g., liking, trust), a pattern of...

We report the results of the first study designed to evaluate the feasibility and acceptability of an HIV prevention intervention focused on concurrent sexual partnerships. Mathematical models and longitudinal studies of stable couples indicate concurrency plays a critical role in sustaining...

The spread of a disease through human populations can be significantly altered by patterned networks of social contact. Largely in response to AIDS, the way in which social networks channel disease has recently become the focus of a sustained modeling effort in epidemiology. The challenge has...

This paper examines the potential impact of concurrent partnerships on HIV spread in Uganda using microsimulation. We represent a population of individuals, the sexual partnerships that they form and dissolve over time, and the spread of an infectious disease as a stochastic process. Data from...

This paper uses simulation to examine the role that measurement error may play in survey estimates of concurrent partnerships. Concurrent partnerships accelerate the spread of a sexually transmitted infection, making data on concurrency important for modeling and public health purposes. Methods...
