Early Flu Season Grips Europe, Italy sees Sharp Rise in cases
Rome, Italy - An unusually early influenza season is sweeping across Europe, with Italy experiencing a particularly intense start, according to new data released by the Istituto Superiore di Sanità (ISS). The surge in respiratory illnesses comes roughly a month ahead of schedule, mirroring a trend observed during the 2022-2023 season. While the situation varies across the continent, Italy is already reporting a significant increase in infections.
The ISS’s latest update, available on Lab24, estimates approximately 16,400 influenza cases in the 47th week of 2025. This represents an 8.7% increase compared to the previous week’s incidence of 8.24. The early onset and rapid spread raise concerns about potential strain on healthcare systems as winter approaches, prompting health officials to monitor the situation closely.
Currently, Rhinoviruses, influenza viruses, and Adenoviruses are the most prevalent respiratory viruses circulating in Italy, contributing to a rise in acute respiratory infections (ARI). While influenza positivity rates are climbing, cases of COVID-19 are decreasing. Levels of the Respiratory Syncytial Virus (RSV) remain low.
In hospitals, Rhinoviruses are the most frequently detected, followed by influenza viruses.SARS-CoV-2 is also present, but with a notably higher incidence among individuals aged 65 and over. Health authorities are urging preventative measures, including vaccination, to mitigate the impact of the early flu season.
