Infection Detection through Temperature Monitoring 通过体温监测检测感染
AIAA SCITECH 2022 Forum
Pub Date : 2022-01-03 DOI: 10.2514/6.2022-1770
H. Seywald
This paper describes the theory behind a smartphone application designed to detect COVID-19 infections through temperature monitoring. COVID-19 infections can cause a temperature increase typically around 0.5 C over a slow, moderate, nonlinear multi-day course averaging 5 days. To enable detection of this increase, filtering techniques are applied to simultaneously establish a base temperature and to detect a COVID-typical deviation from that base temperature. Numerical simulations are developed to assess the effectiveness of the application in detecting the presence of an infection in individuals and in groups. The measure of effectiveness is the number of new-infections incurred before the initial infection is detected. It is observed that group testing and group analysis becomes increasingly effective as the infection rate is increased, e.g. R0 ≥ 3. If the infection rate is low, e.g. R0 ≤ 1.1, group analysis becomes ineffective because, at any given time, too few people are infected simultaneously to be detectable in the group average. The effectiveness of individual testing and the individual analysis is unaffected by the infection rate. This result is significant since it has to be expected that widespread vaccination as well as social distancing efforts significantly reduce the infection rate making outbreaks challenging to spot. © 2022, American Institute of Aeronautics and Astronautics Inc..

本文介绍了一款智能手机应用程序背后的理论，该应用程序旨在通过体温监测来检测COVID-19感染。COVID-19感染可导致温度在缓慢、适度、非线性的多日过程中升高0.5℃左右，平均为5天。为了能够检测到这种增加，应用过滤技术同时建立基准温度并检测与该基准温度的典型偏差。开发了数值模拟来评估该应用程序在检测个人和群体感染存在方面的有效性。有效性的衡量标准是在发现最初感染之前发生的新感染的数量。观察到群体检测和群体分析随着感染率的增加而越来越有效，如R0≥3。如果感染率很低，例如R0≤1.1，则群体分析无效，因为在任何给定时间，同时感染的人数太少，无法在群体平均值中检测到。个体检测和个体分析的有效性不受感染率的影响。这一结果意义重大，因为必须预期广泛接种疫苗以及保持社会距离的努力将大大降低感染率，使疫情难以发现。©2022，美国航空航天学会。版权所有。
