社会网络分析已经成为理解传染病传播和慢性疾病行为风险的核心。网络通常被视为疾病或其风险因素传播的渠道。然而，社会关系也会降低慢性病的发病率，以及潜在的传染病。很少同时考虑这些相反的影响。我们展示了腹泻病如何以及为什么在远离该地区人口中心的厄瓜多尔农村村庄传播得更慢。与外界接触减少是偏远村庄腹泻患病率相对较低的部分原因。但同样或更重要的是，偏远社区个人之间的社会联系更加紧密，这有助于减少腹泻疾病传播的个人和集体做法的传播。
Social network analysis has become central to understanding the spread of infectious diseases and behavioral risks for chronic disease. Networks are typically seen as conduits for spread of disease or risk factors thereof. However, social relationships also reduce incidence of chronic disease, and potentially infectious diseases as well. Seldom are these opposing effects considered simultaneously. We show how and why diarrheal disease spreads more slowly to and within rural Ecuadorian villages that are more remote from the area’s population center. Reduced contact with outside individuals partially accounts for remote villages’ relatively lower prevalence of diarrheal disease. But equally or more important is greater density of social ties between individuals in remote communities, which facilitates spread of individual and collective practices that reduce transmission of diarrheal disease.
