Weeks 31–35/2016 (1 August–4 September 2016)


  • Influenza activity in the WHO European Region has remained at low levels, with all countries reporting low-intensity influenza activity.
  • Few influenza viruses were detected among both sentinel and non-sentinel specimens.
  • Data from the 16 countries or regions reporting to the European monitoring of excess mortality for public health action (EuroMOMO) project indicate that all-cause mortality was within the normal range in reporting countries during this period.



  • Most of the viruses that were antigenically and/or genetically characterized during the 2015–2016 influenza season were similar to those recommended for inclusion in the trivalent or quadrivalent vaccines for this season in the northern hemisphere (see the May, June and July characterization reports from the European Centre for Disease Prevention and Control – ECDC).
  • Recommendations on the composition of seasonal influenza vaccines for the 2016–2017 season in the northern hemisphere call for replacement of the A(H3N2) component with a more recent virus and inclusion of a B/Victoria-lineage virus in trivalent vaccines.


Global update 

  • As of week 33, influenza activity was varied in countries of temperate South America and had increased steadily over several weeks in South Africa and Oceania. Influenza activity in the temperate zone of the northern hemisphere was at interseasonal levels.
  • Additional information on global influenza activity is available here.
