Influenza activity increasing in Europe

Influenza transmission is increasing in the WHO European Region, spreading from west to east. Influenza activity across the Region currently varies from widespread, mainly in the west and north, to no or sporadic activity in the east.

As was the case during the 2011/2012 influenza season, A(H1N1)pdm09, A(H3N2) and type B viruses are all circulating. Influenza infection is normally mild, but may cause serious illness, particularly among people who are elderly or have underlying medical conditions. Nevertheless, A(H1N1)pdm09 infection has caused severe and fatal disease in younger, otherwise healthy people.

As usual in the winter season, health care authorities should be prepared for an increase in cases of respiratory illness in both outpatient care and hospitals across the Region.
