背景资料：量化与通过社会接触传播传染病相关的人际互动对于预测疾病动态至关重要，但来自低资源环境的数据仍然很少。我们在乌干达农村进行了一项社会接触调查，参与者被要求回忆有关频率，类型，以及在前一天期间持续>= 5分钟（此后定义为“接触”）的任何会话遭遇的社会人口统计学特征。“偶然接触”（即= 65岁）的估计数最少（P < 0.001）。一个强大的年龄增长模式，特别是在家庭以外，越来越多的接触发生在离家较远的地方。年龄在25-64岁的成年人往往旅行更频繁，比别人更远，男性旅行更频繁比females.Conclusion：我们的研究提供了详细的信息，在非洲设置的接触模式和空间特征。因此，它填补了一个重要的知识空白，将有助于更准确地预测传输动态和控制策略在这些领域的影响。
Background: Quantification of human interactions relevant to infectious disease transmission through social contact is central to predict disease dynamics, yet data from low-resource settings remain scarce.Methods: We undertook a social contact survey in rural Uganda, whereby participants were asked to recall details about the frequency, type, and socio-demographic characteristics of any conversational encounter that lasted for >= 5 min (henceforth defined as 'contacts') during the previous day. An estimate of the number of 'casual contacts' (i.e. = 65 years) the fewest (P < 0.001). A strong age-assortative pattern was seen, particularly outside the household and increasingly so for contacts occurring further away from home. Adults aged 25-64 years tended to travel more often and further than others, and males travelled more frequently than females.Conclusion: Our study provides detailed information on contact patterns and their spatial characteristics in an African setting. It therefore fills an important knowledge gap that will help more accurately predict transmission dynamics and the impact of control strategies in such areas.
