Summary

  • On 21 August, the National Reference Laboratory (NRL) for Avian Influenza and Newcastle Disease confirmed as positive for Avian Influenza A virus a fattening turkey farm in Verona province, Veneto region (subtype H5), and a game birds farm in Lodi province, Lombardy (subtype H5N8).
  • At the moment of the epidemiological inquiry, in the fattening turkey farm there were 13.248 turkeys (females, 87 day-old).
  • The symptoms started in the days before the confirmation, in particular from Friday there was a sudden increase in the mortality and a decrease in water and feed intake.
  • Culling, cleaning and disinfection procedures are ongoing for this case, while the pre-emptive culling of an at-risk turkey farm, linked to the outbreak, has been planned for the next days.
  • Regarding the last case in Lombardy region, in the farm were present about 23.000 birds belonging to different species (pheasants, partridges, mallard hybrids), and the samples were collected after a clinical suspect.
  • Further information on virus characterization and phylogenetic analysis on the two viruses will be provided as soon as available.

Summary

    • In the temperate zone of the southern hemisphere and in some countries of South and South East Asia, high levels of influenza activity continued to be reported.
    • In Central America and the Caribbean influenza activity continued to be reported in a few countries.
    • Influenza activity remained at low levels in the temperate zone of the northern hemisphere.
    • Worldwide, influenza A(H3N2) viruses are predominating.
  • In temperate South America, influenza activity, severe acute respiratory infection (SARI) and influenza like illness (ILI) indicators decreased in the countries reporting data.
    • Influenza A(H3N2) viruses predominated in the region with some B virus activity reported as well.
  • In Southern Africa, influenza activity was reported from several countries but appeared to have peaked already in South Africa, with influenza A(H3N2) viruses predominantly detected.
  • In Oceania, seasonal influenza activity continued to increase, with influenza A(H3N2) and B viruses present in the region.
  • In tropical South America, influenza activity remained low.
  • In the Caribbean and Central American countries, respiratory illness indicators and influenza activity remained low in general with a few exceptions but Respiratory Syncytial Virus (RSV) activity was increasing.
  • In Southern Asia, increased influenza A(H1N1)pdm09 virus detections were reported in India, Myanmar and Nepal in recent weeks.
  • In South East Asia, increased influenza activity was reported in recent weeks, with all seasonal influenza subtypes present in the region.
  • In East and Western Asia, influenza activity remained low in general.
  • In Western Africa, influenza activity continued to be reported, with influenza A(H1N1)pdm09 and A(H3N2) viruses co-circulating in in Côte d’Ivoire, Ghana, and Togo, and influenza B Victoria lineage predominant in Senegal.
    • Few influenza detections were reported in Eastern and Middle Africa.
  • In Northern Africa, no influenza virus detections were reported.
  • In Central Asia, there were no updated reports on virus detections or respiratory illness indicators.
  • In Europe and North America, little to no influenza activity was reported.

National Influenza Centres (NICs) and other national influenza laboratories from 75 countries, areas or territories reported data to FluNet for the time period from 24 July 2017 to 06 August 2017 (data as of 2017-08-18 03:36:54 UTC).

The WHO GISRS laboratories tested more than 50456 specimens during that time period.

8401 were positive for influenza viruses, of which 7644 (91%) were typed as influenza A and 757 (9%) as influenza B.

Of the sub-typed influenza A viruses, 779 (11.6%) were influenza A(H1N1)pdm09 and 5930 (88.4%) were influenza A(H3N2).

Of the characterized B viruses, 168 (63.4%) belonged to the B-Yamagata lineage and 97 (36.6%) to the B-Victoria lineage.

Time period covered: 2016 – 2017

Summary

  • In the course of the 2016–2017 influenza season, nearly 146 000 influenza detections across the EU/EAA region have been reported.
  • Influenza type A viruses have prevailed over type B with A(H3N2) viruses, greatly outnumbering A(H1N1)pdm09 and B/Yamagata-lineage detections representing 73% of the type B viruses assigned to a lineage.
  • During the 2016–2017 influenza season, A(H1N1)pdm09 activity has been low compared to the previous season, and the viruses involved remained antigenically indistinguishable by post-infection ferret antisera raised against the A/California/7/2009 vaccine virus.
  • Studies with post-vaccination and post-infection human sera showed that a significant proportion could distinguish representative viruses of subclades 6B.1 and 6B.2 from the vaccine virus.
  • Moreover, the reports of high levels of infection associated with A(H1N1)pdm09 in many countries, and the great dominance of subclade 6B.1 viruses among the H1N1pdm09 viruses in circulation led to the recommendation made by WHO to include an A/Michigan/45/2015-like virus in vaccines for the 2017 southern hemisphere and 2017–18 northern hemisphere influenza seasons.
