Resurgence of in Lazio: A Cross-Age Surveillance Study from Two Referral Hospitals.

Since late 2023, an increase in infections has been noticed in Europe, particularly among children. Our data showed the upward trend of cases in the Lazio region, even among adults with severe influenza-like illnesses, highlighting the necessity for maintaining high vaccination rates across both children and adults. These findings underscore the urgent need for clinicians to maintain a high index of suspicion for in patients with respiratory symptoms, prioritize nasopharyngeal swabs for accurate diagnosis, assess for co-infections, verify booster vaccination status in adults, and support timely reporting to public health authorities.
