In a previous work (Huber etal. 2020 Phys. Biol. 17 065010), we discussed virus transmission dynamics modified by a uniform clustering of contacts in the population: close contacts within households and more distant contacts between households. In this paper, we discuss testing and tracing in such a stratified population. We propose a minimal tracing strategy consisting of random testing of the entire population plus full testing of the households of those persons found positive. We provide estimates of testing frequency for this strategy to work.

流行病中基于家庭的测试和追踪的最小模型

在之前的一项工作中（Huber等人， 2020 Phys. Biol. 17 065010），我们讨论了由人口中接触者的统一聚类修改的病毒传播动态：家庭内部的密切接触者和家庭之间的更远距离的接触者。在本文中，我们讨论了在这样一个分层人群中的测试和追踪。我们提出了一种最低限度的追踪策略，包括对整个人口进行随机检测以及对发现阳性的人的家庭进行全面检测。我们提供了使该策略起作用的测试频率估计值。
