论文摘要
与公告板接触跟踪相比，我们介绍了对手动接触跟踪的有效性的评估。我们表明，公告板的联系跟踪在生殖数，持续时间，流行率和发病率方面给出了可比的结果，但资源较少，更易于实施，并且提供了更广泛的隐私选项。经典的接触追踪着重于与传染性人靠近的个人联系。公告委员会的方法着重于识别传染性人访问的位置，然后与那些位置的人联系。我们提出结果，比较它们对疾病总体生殖数量以及发病率和患病率的影响。我们通过建立一个基于易感的裸露感染和疾病传播框架的新离散时间随机模型来评估它们。我们通过校准该模型与SARS-COV-2兼容，以量化这两种接触追踪模型的有效性，以量化仿真实验。我们的实验表明，基于位置的公告板接触跟踪可以改善手动触点跟踪。
We present an evaluation of the effectiveness of manual contact tracing compared to bulletin board contact tracing. We show that bulletin board contact tracing gives comparable results in terms of the reproductive number, duration, prevalence and incidence but is less resource intensive, easier to implement and offers a wider range of privacy options. Classical contact tracing focuses on contacting individuals whom an infectious person has been in proximity to. A bulletin board approach focuses on identifying locations visited by an infectious person, and then contacting those who were at those locations. We present results comparing their effects on the overall reproductive number as well as the incidence and prevalence of disease. We evaluate them by building a new discrete time stochastic model based on the Susceptible Exposed Infectious and Recovered (SEIR) framework for disease spread. We conduct simulation experiments to quantify the effectiveness of these two models of contact tracing by calibrating the model to be compatible with SARS-CoV-2. Our experiments show that location-based bulletin board contact tracing can improve manual contact tracing.
