Seasonal influenza in the WHO European Region, 2017-2018 early season (2018)



The main objectives of this situation analysis are:

  • to provide a description of the epidemiological pattern of seasonal influenza in the first affected Member States;
  • to estimate the progression of influenza activity and the possible impact on susceptible and at-risk populations for the rest of the season; and
  • to compare circulating viruses with current vaccine strains and describe susceptibility to neuraminidase inhibitors (NAI).

This analysis can be used to guide local public health authorities, for instance in reinforcing vaccination programmes in certain risk groups, directing antiviral policies or allocating appropriate health care resources.
