Influenza is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and sometimes the lungs. It can cause mild to severe illness, and at times can lead to death. The best way to prevent flu is by getting a flu vaccine each year.
The Flu Awareness Campaign is marked across the WHO European Region every year in October. It aims to raise awareness of the importance of vaccination for people’s health and well-being and to increase the uptake of seasonal influenza vaccination of people with underlying risk factors.
Although the overall number of influenza detections in the majority of EU/EEA countries is still low, indications show that influenza circulation is above the seasonal threshold in Croatia, which is unusually early. The main reported subtype among the cases recorded in EU/EEA during the past month is A(H3N2), which disproportionally affects older people, and is associated with lower vaccine effectiveness. This is a sign that the upcoming influenza season could be severe for elderly people, and that influenza patterns may vary between countries in terms of timing.
