The European Centre for Disease Prevention and Control (ECDC) recorded just three confirmed cases of influenza virus in ‘sentinel’ health centres – a sample of GP practices used for public health surveillance.
The ECDC’s weekly flu surveillance report of the 8th of May says all 26 countries which feed into its monitoring system saw low influenza activity. Two countries reported a total of 11 hospitalised cases with a severe acute respiratory infection, four of which tested positive for influenza virus infection.

This vaccine’s composition is updated twice per year to reflect the flu seasons in the northern and southern hemispheres.
