Seasonal influenza has to be taken seriously. Each year, approximately ten per cent of Europe's population is infected, and influenza-related complications cause hundreds of thousands of hospitalisations across Europe. Older people, younger children and those with chronic conditions suffer the most, but everyone is at risk of developing serious complications – which include pneumonia, myocarditis and encephalitis – that may result in death.
ECDC monitors and reports
on influenza activity in Europe on a weekly basis throughout the flu season.
