Early Flu Circulation in Europe: 

Why Immediate Vaccination and Rapid Diagnostics Are Critical

24 November 2025

As Europe heads into the 2025 winter season, the European Centre for Disease Prevention and Control (ECDC) has issued an urgent warning: influenza viruses are circulating 3–4 weeks earlier than in previous years. This unexpected early flu activity has prompted the ECDC to call for “vaccination without delay” and greater preparedness among public health authorities, hospitals, pharmacies, and diagnostic laboratories.

With early flu circulation comes increased pressure on healthcare resources. But even more importantly, this year’s flu wave is overlapping with COVID-19, RSV, and other respiratory pathogens, making it difficult for clinicians to differentiate infections based on symptoms alone. In this context, rapid, reliable, and multiplex respiratory diagnostic testing becomes essential for faster decision-making, treatment, and outbreak control.

Why Is Flu Spreading Earlier This Year in Europe?

ECDC surveillance reports show that the dominant strain currently circulating is Influenza A(H3N2), subclade K variant, which is known to affect older adults more severely. Flu infections are increasing rapidly across Germany, France, Italy, Spain, the Netherlands, Norway, and the UK, with special concern for:

• Elderly adults (65+)

• Pregnant women

• Immunocompromised patients

• Individuals with chronic heart or lung diseases

• Residents in nursing homes and long-term care facilities

European hospitals are preparing for a season where flu, RSV, and COVID-19 may peak at the same time, making triage, diagnosis, and treatment more complex than usual.

Vaccination Alone Is Not Enough — Testing Plays a Vital Role

While vaccination offers the best protection against influenza, many individuals are unvaccinated or only partially protected. Moreover, flu vaccines do not protect against RSV, SARS-CoV-2, or adenovirus, which often present with similar symptoms.

This is why healthcare professionals across Europe are turning to rapid respiratory diagnostics, especially multiplex antigen and PCR-based detection, to:

✔ Quickly distinguish between influenza, COVID-19, RSV, and other infections
✔ Enable early antiviral treatment and prevent severe outcomes
✔ Avoid unnecessary antibiotic prescriptions
✔ Support outbreak control in hospitals, clinics, and care facilities
✔ Reduce overall healthcare burden during the peak season
