Adnkronos (Adnkronos) – The influenza and winter respiratory virus bulletin is back. And according to the first report from the RespiVirNet surveillance system, in the last week—between November 2nd and 8th—an estimated 478 cases of acute respiratory infections (ARI) were recorded in the community, corresponding to a total community incidence of 8,5 cases per 1.000 residents. As usual, children are most affected: the highest incidence is observed in the 0-4 age group, with approximately 30 cases per 1.000 residents.
Overall, the incidence rate of respiratory viruses is in line with that recorded in the 2025-2026 season in the same period.
Across the peninsula, the incidence of respiratory infections is at baseline levels in Friuli Venezia Giulia, Liguria, Tuscany, Umbria, and Sicily and low in all other regions that provided data except Campania, where it is very high.
Which viruses are circulating the most? In the sentinel flow, the report published on the Istituto Superiore di Sanità (ISS) portal explains, the highest positivity rates among circulating respiratory viruses were recorded for rhinoviruses (25,7%), parainfluenza viruses (17,1%), and adenoviruses (8,6%), while the positivity rate for true influenza viruses is 5,7%.
Among respiratory viruses, the highest positivity rates among hospital admissions were found for rhinoviruses (29%), parainfluenza viruses (6,5%), and coronaviruses other than SARS-CoV-2 (6%). For influenza and SARS-CoV-2, the highest positivity rates were observed in the over-65 age group. In this regard, the ISS recalls that "a vaccination campaign against Covid-19 has been launched, as well as for influenza, for the highest-risk groups, including all people over 60 years of age.
