Toward Accurate Spatiotemporal COVID-19 Risk Scores Using High-Resolution Real-World Mobility Data

چکیده
As countries look toward re-opening of economic activities amidst the ongoing COVID-19 pandemic, ensuring public health has been challenging. While contact tracing only aims to track past infected users, one path safe reopening is develop reliable spatiotemporal risk scores indicate propensity disease. Existing works which aim at developing either rely on compartmental model-based reproduction numbers (which assume uniform population mixing) or coarse-grain spatial based number (R0) and macro-level density-based mobility statistics. Instead, in this article, we a Hawkes process-based technique assign relatively fine-grain temporal by leveraging high-resolution data cell-phone originated location signals. also depend factors specific an individual, including demography existing medical conditions, primary mode disease transmission via physical proximity contact. Therefore, focus density behaviour. We demonstrate efficacy developed simulation real-world data. Our results show that can provide useful insights facilitate re-opening.

Inferring Real-World Relationships from Spatiotemporal Data
The pervasiveness of GPS-enabled mobile devices and the popularity of location-based services have generated, for the first time, massive data that represents the movements of people in the real world at a high resolution, aka spatiotemporal data. Such collections of spatiotemporal data constitute a rich source of information for studying various social behaviors, and in particular, give a boos...

Approximately two–thirds of healthcare costs are accounted for by 10% of the patients. Identifying such high-cost patients early can help improve their health and reduce costs. Data from the Arizona Health Care Cost Containment System provides a unique opportunity to exploit state-of-the-art data analysis algorithms to mine data and provide actionable findings that can aid cost containment.
