Overview
- RespiVirNet reported nearly 450,000 new acute respiratory infections during Nov. 10–16, bringing the season total above 2.1 million.
- Laboratory surveillance shows influenza and RSV positivity remain low, with higher detections for rhinoviruses, SARS‑CoV‑2 and parainfluenza viruses.
- UK scientists recently flagged seven mutations in an H3N2 clade, and Italian experts are watching for signs of wider circulation.
- Sudden temperature drops and more time spent indoors are helping transmission, particularly among young children who show the highest incidence.
- Vaccination is recommended for people over 60 and those with chronic or immune‑weakening conditions, yet elderly uptake last season was 52.5% versus a 75% goal and Italy attributes about 8,000 deaths a year to influenza and its complications.
