The final dissemination report summarises the communication and dissemination activities implemented during the UNITED4Surveillance Joint Action, based on the consolidated partner dataset dated 19 June 2026. The report shows that dissemination was not a single central activity, but a consortium-wide effort implemented through many national, professional and European channels.The updated dataset contains 441 retained activity records: 169 communication activities and 272 dissemination activities. Activity increased substantially in the second reporting period, with 295 records compared with 146 in the first reporting period. This development reflects the natural progress of the project from initial visibility and stakeholder engagement towards wider sharing of outputs, tools, pilot experiences and lessons learned.The activities covered a broad mix of channels, including websites, social media, newsletters, press and media outputs, meetings, workshops, trainings, conferences, reports, scientific outputs and direct stakeholder engagement. In addition, 167 records include links and 280 records contain information on how many people were reached.Based on these results, we conclude that the overall picture is positive. Partners made visible and sustained efforts to communicate the purpose of UNITED4Surveillance, engage relevant audiences and disseminate project results. Their contributions helped connect the project with public health authorities, laboratories, epidemiologists, researchers, healthcare professionals, policy stakeholders and wider audiences, thereby strengthening the practical value and future uptake of the project results.
