[From yesterday's lessons to tomorrow's actions: COVID-19 and contact tracing in Italy].

The Italian Association of Epidemiology's experience during the COVID-19 pandemic and its collaboration on a national project focused on contact tracing have prompted significant insights essential for the management of future pandemics in Italy and the development of new pandemic plans. In particular, the Italian Association of Epidemiology highlighted the need to collect, analyse and interpret data, and produce indicators of effectiveness and efficiency in a consistent manner across the country to support the governance of the pandemic response. During the COVID-19 pandemic in Italy, this capacity was severely hampered by structural and regulatory factors and the limited availability of specific expertise. The lack of applications developed for contact tracing purposes and the absence of interoperability between existing information systems highlighted the need to invest in integration among ICT, Epidemiology, and Public Health Services. The absence of predefined indicators made it impossible to compare different organisational solutions for contact tracing. From the regulatory point of view, there is an urgent need for clarification of the legitimacy and legal basis of the use of data already available to the National Health System collected for different purposes to be used for the performance of proactive medicine and prevention activities. Finally, investment in training for health workers and decision-makers at all levels and community awareness raising are essential to building a resilient community. The Italian National Pandemic Plan 2024-2028 is an opportunity to prepare an effective and efficient response to future health emergencies, through coordinated plans and the valorisation of the pandemic experience.
