关于COVID-19的互联网搜索工作以及潜在的公共干预措施和流行病学状况

Internet search effort on Covid-19 and the underlying public interventions and epidemiological status

Aristides Moustakas

摘要:

疾病传播是一个复杂的现象,需要采取跨学科的办法。2019冠状病毒病在很短的时间内表现出全球空间传播,导致全球大流行。使用政府干预措施(如学校关闭、行动限制、国内和国际旅行限制、呆在家里的要求、口罩要求、财政支持措施)和流行病学变量(如新发病例和新发死亡病例)作为潜在解释协变量,分析了希腊以2019冠状病毒病为主题的一年每周时间尺度的网络搜索数据。使用机器学习分析了网络搜索对Covid-19的影响与16个解释协变量之间的关系。将网络搜索时间与相应的流行病学情况进行比较,以同一周的Rt表示。结果表明,训练后的模型在实际和预测的网络搜索努力之间表现出R2 = 91%的拟合。预测网络搜索努力的前五个变量是新的死亡人数,向非希腊国民开放国际边界,新病例,检测政策和内部流动的限制。网络搜索在Rt达到峰值的同一周达到峰值,尽管新的死亡或新病例在这些日期没有达到峰值,并且Rt很少在公共媒体上报道。由于网络搜索努力和Rt在2020年8月1日至15日(旅游旺季)达到峰值,因此讨论了这一点的影响。

英文摘要:

Disease spread is a complex phenomenon requiring an interdisciplinary approach. Covid-19 exhibited a global spatial spread in a very short time frame resulting in a global pandemic. Data of web search effort in Greece on Covid-19 as a topic for one year on a weekly temporal scale were analyzed using governmental intervention measures such a s school closures, movement restrictions, national and international travelling restrictions, stay at home requirements, mask requirements, financial support measures, and epidemiological variables such as new cases and new deaths as potential explanatory covariates. The relationship between web search effort on Covid-19 and the 16 in total explanatory covariates was analyzed with machine learning. Web search in time was compared with the corresponding epidemiological situation, expressed by the Rt at the same week. Results indicated that the trained model exhibited a fit of R2 = 91% between the actual and predicted web search effort. The top five variables for predicting web search effort were new deaths, the opening of international borders to non-Greek nationals, new cases, testing policy, and restrictions in internal movements. Web search peaked during the same weeks that the Rt was peaking although new deaths or new cases were not peaking during those dates, and Rt rarely is reported in public media. As both web search effort and Rt peaked during 1-15 August 2020, the peak of the tourist season, the implications of this are discussed.
