Since the early stage of the current pandemic, digital contact tracing (DCT) through mobile phone apps, called "Immuni", has been introduced to complement manual contact tracing in Italy. Until 31 December 2021, Immuni identified 44,880 COVID-19 cases, which corresponds to less than 1% of total COVID-19 cases reported in Italy in the same period (5,886,411). Overall, Immuni generated 143,956 notifications. Although the initial download of the Immuni app represented an early interest in the new tool, Immuni has had little adoption across the Italian population, and the recent increase in its download is likely to be related to the mandatory Green Pass certification for conducting most daily activities that can be obtained via the application. Therefore, Immuni failed as a support tool for the contact tracing system. Other European experiences seem to show similar limitations in the use of DTC, leaving open questions about its effectiveness, although in theory, contact tracing could allow useful means of "proximity tracking".
自当前疫情早期以来，意大利已通过手机应用程序（称为“Immuni”）引入了数字接触者追踪（DCT），以补充人工接触者追踪。截至 2021 年 12 月 31 日，Immuni 已发现 44880 例 COVID-19 病例，不到同期意大利报告的 COVID-19 总病例数（5886411 例）的 1%。总体而言，Immuni 共生成了 143956 条通知。尽管 Immuni 应用程序的初始下载代表了人们对新工具的早期兴趣，但它在意大利人口中的采用率一直很低，最近其下载量的增加可能与获取应用程序中进行大多数日常活动的强制性绿色通行证认证有关。因此，Immuni 作为接触者追踪系统的支持工具失败了。其他欧洲的经验似乎表明，DTC 的使用存在类似的局限性，尽管从理论上讲，接触者追踪可以提供有用的“接近跟踪”手段，但仍存在有效性方面的问题。
