Influenza remains a significant public health issue, with seasonal trends varying across regions. This study provides a comprehensive analysis of influenza virus trends in Italy, leveraging epidemiological and virological data from the Istituto Superiore di Sanit\u00e0 (ISS). The primary objective is to assess influenza activity at both national and regional levels, highlighting variations in incidence rates and viral subtype circulation during the 2023\/2024 season. Methods. We conducted a systematic approach to data collection, processing, and visualization, utilizing influenza surveillance data from ISS. Incidence rates, subtype distribution, and co-circulating respiratory viruses were analyzed to identify key trends. Results. Our findings reveal a significant increase in influenza cases during the 2023\/2024 season, with incidence rates surpassing pre-pandemic levels. Notably, changes in the circulation of influenza A(H3N2) and influenza B were observed, alongside the presence of other respiratory viruses such as RSV and rhinovirus. Conclusions. This study underscores the importance of real-time surveillance, transparent data sharing, and advanced visualization tools in guiding public health responses. By integrating lessons from COVID-19, we highlight the necessity of standardized surveillance frameworks to enhance preparedness for future seasonal outbreaks and potential pandemics.<\/jats:p>","DOI":"10.3390\/idr17020020","type":"journal-article","created":{"date-parts":[[2025,2,28]],"date-time":"2025-02-28T02:48:37Z","timestamp":1740710917000},"page":"20","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Comprehensive Analysis of Influenza Viruses\u2019 Trends in Italy: Insights from a Nationwide and Regional Perspective"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9485-3877","authenticated-orcid":false,"given":"Francesco","family":"Branda\u00a0","sequence":"first","affiliation":[{"name":"Unit of Medical Statistics and Molecular Epidemiology, Universit\u00e0 Campus Bio-Medico di Roma, 00128 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2585-7567","authenticated-orcid":false,"given":"Nicola","family":"Petrosillo\u00a0","sequence":"additional","affiliation":[{"name":"Infection Prevention & Control\/Infectious Disease Service, Fondazione Policlinico Universitario Campus Bio-Medico, 00128 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1628-9948","authenticated-orcid":false,"given":"Dong Keon","family":"Yon\u00a0","sequence":"additional","affiliation":[{"name":"Center for Digital Health, Medical Science Research Institute, Kyung Hee University College of Medicine, Seoul 02448, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3866-9239","authenticated-orcid":false,"given":"Massimo","family":"Ciccozzi\u00a0","sequence":"additional","affiliation":[{"name":"Unit of Medical Statistics and Molecular Epidemiology, Universit\u00e0 Campus Bio-Medico di Roma, 00128 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3501-714X","authenticated-orcid":false,"given":"Fabio","family":"Scarpa\u00a0","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences, University of Sassari, 07100 Sassari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,27]]},"reference":[{"key":"ref_1","first-page":"45","article-title":"Human metapneumovirus: Review of an important respiratory pathogen","volume":"25","author":"Panda","year":"2014","journal-title":"Sci.
