The social network paradigm provides a set of concepts and methods useful for studying the structure of a population through which infectious agents transmitted during close personal contact spread, and an opportunity to develop improved disease control programs. The research discussed was a first attempt to use a social network approach to better(More)

This study describes the risk network structure of persons with HIV infection during its early epidemic phase in Colorado Springs, USA, using analysis of community-wide HIV/AIDS contact tracing records (sexual and injecting drug partners) from 1985 to 1999. Paired partner information from other STD/HIV programme records was used to augment network(More)
Gonococcal infection in Colorado Springs, Colorado, is concentrated in about 1% of the population. The social groups at risk are characterized as young, nonwhite, heterosexual, and connected to the military. They exhibit residential proximity by clustering in "core" census tracts; 51% of cases were in four tracts. They demonstrate residential stability and(More)
Disease control efforts directed at human immunodeficiency virus are predicated on the need to reduce personal risk behaviors; that approach may not adequately reflect the complicated interplay between personal behaviors and the social setting in which they occur. Efforts to date, including the application of population ecology, the development of the core(More)
OBJECTIVE To study prospectively social networks and behavior in a group of persons at risk for HIV because of their drug-using and sexual practices, with particular emphasis on the interaction of risks and concomitant network structure. METHODS A longitudinal study was conducted of 228 respondents in Atlanta, Georgia in six inner-city community chains of(More)
OBJECTIVE The objective of this study was to examine the relationship between social distance (measured as the geodesic, or shortest distance, between 2 people in a connected network) and geographic distance (measured as the actual distance between them in kilometers [km]). STUDY We used data from a study of 595 persons at risk for HIV and their sexual(More)
We previously reported on the causes of death in a 30-year open cohort of 1,969 prostitute women. Excess mortality was mostly accounted for by homicide, suicide, drug and alcohol toxicity, and AIDS, with AIDS deaths occurring in prostitutes identified as injecting drug users. Presently, we examine observed mortality trends in light of the literature on(More)
OBJECTIVE To prospectively study changes in the social networks of persons at presumably high risk for HIV in a community with low prevalence and little endogenous transmission. METHODS From a cohort of 595 persons at high risk (prostitutes, injecting drug users, and sexual partners of these persons) and nearly 6000 identified contacts, we examined the(More)
