在2019年冠状病毒病(新冠肺炎)大流行之后，接触者追踪已成为控制2019年严重急性呼吸综合征冠状病毒(SARS-CoV-2)传播战略的关键要素。鉴于SARS-CoV-2病毒的迅速和强烈传播，数字接触者追踪已成为支持遏制和缓解努力的潜在补充工具。早期的建模研究强调了数字接触者追踪打破传播链的潜力，谷歌和苹果随后开发了曝光通知(EN)框架，使其适用于绝大多数智能手机。越来越多的政府已经推出或宣布了基于EN的联系人追踪应用程序，但其有效性仍不清楚。在这里，我们报告了在瑞士部署数字接触者追踪应用程序的早期发现。我们演示了数字接触者追踪到暴露接触者的原则证明，然后这些接触者的SARS-CoV-2检测呈阳性。这表明数字接触者追踪是控制SARS-CoV-2传播的有效辅助工具。持续的技术改进和国际兼容性可以进一步提高效力，特别是跨越国界。
In the wake of the pandemic of coronavirus disease 2019 (COVID-19), contact tracing has become a key element of strategies to control the spread of severe acute respiratory syndrome coronavirus 2019 (SARS-CoV-2). Given the rapid and intense spread of SARS-CoV-2, digital contact tracing has emerged as a potential complementary tool to support containment and mitigation efforts. Early modelling studies highlighted the potential of digital contact tracing to break transmission chains, and Google and Apple subsequently developed the Exposure Notification (EN) framework, making it available to the vast majority of smartphones. A growing number of governments have launched or announced EN-based contact tracing apps, but their effectiveness remains unknown. Here, we report early findings of the digital contact tracing app deployment in Switzerland. We demonstrate proof-of-principle that digital contact tracing reaches exposed contacts, who then test positive for SARS-CoV-2. This indicates that digital contact tracing is an effective complementary tool for controlling the spread of SARS-CoV-2. Continued technical improvement and international compatibility can further increase the efficacy, particularly also across country borders.
