Avian Influenza H5N8 in White-tailed Eagles 2016/2017

+++ Documented Cases of H5N8 in White-tailed Eagles +++ General Information on the Outbreak +++ Maps +++ Updates +++ Current News +++

Note: “To date, no human infections with this virus have ever been reported world-wide and the risk of zoonotic transmission to the general public in EU/EEA countries is considered to be very low.” (European Centre for Disease Prevention and Control. Outbreak of highly pathogenic avian influenza A(H5N8) in Europe – 18 November 2016. Stockholm: ECDC; 2016)

Fast Facts: Highly Pathogenic Avian Influenza (H5N8)

  • Three types of influenza viruses exist: A, B and C
  • The avian influenza viruses belong to type A
  • Avian influenza (avian flu, bird flu) = a disease mainly of birds
  • There are two groups or categories: Low pathogenic avian influenza (LPAI) and highly pathogenic avian influenza (HPAI)
  • LPAI can mutate into HPAI
  • Within these two groups there are different virus strains. The recent H5N8 strain causes highly pathogenic avian influenza
  • Highly pathogenic avian influenza (HPAI) = high mortality rate in affected birds
  • In which European countries has H5N8 been detected since October 2016? Map: https://iadm.carto.com/me
  • Is it possible to distinguish whether raptors and other scavenging birds ate contaminated carrion or whether they were actually infected with H5N8? A report by the Friedrich-Loeffler-Institute (FLI) says yes. In the latter case a high virus load can be found in the respiratory tract (not in the gastrointestinal tract). (FLI: Hochpathogene Aviäre Influenza, FAQ, 08.12.2016. In German language)

Avian Flu Outbreak 2014/2015 vs. 2016/2017: What´s the Difference?

  • “The pattern of this year’s reports is different to previous years (2014/15) when this virus was first detected in Europe. The mortality events and the species of wild waterfowl affected might indicate possible changes in virus pathogenicity and/or changes in host specificity. However significant uncertainties exist at this early stage and other wild waterfowl species may be infected without mortality.” Samuel Wright, Jonathan Smith, Professor Ian Brown: Updated Outbreak Assessment number 2, 11th November 2016. Department for Environment, Food & Rural Affairs and Animal and Plant Health Agency, UK

  • Map: Detection of highly pathogenic avian influenza virus A(H5N8) in wild birds and poultry, Europe and neighbouring regions, November 2014 to February 2015 and October to December 2016. Source: ECDC http://www.eurosurveillance.org/ViewArt ... leId=22663

  • According to the Friedrich-Loeffler-Institute (FLI), the level of mortality is unprecedented in German wild birds, poultry and zoo birds. 2 December 2016. Update, March 2017 https://www.fli.de/en/news/animal-disea ... wl-plague/

  • Different avian species are susceptible to infection. Since mid-November instances of disease in White-tailed Eagles have been reported from several European countries

  • Update, January 2017: “A new reassortant influenza A(H5N8) virus is responsible for the recent HPAIV outbreak in Germany. The observed differences in pathogenicity for a broad spectrum of waterfowl compared with that of H5N8 viruses from 2014–2015 correlate with a new genome composition of these viruses.” Source: Pohlmann A, Starick E, Harder T, Höper D, Globig A, Staubach C, et al.

  • FLI, 17 May 2017: "The current avian flu epidemic is the most severe and longest-lasting epidemic that has occurred in Europe so far. In total, 29 European states have been or still are concerned." Read more: https://www.fli.de/en/news/animal-disea ... wl-plague/

H5N8 Risk for Humans

  • According to the World Health Organization, “human infection with the A(H5N8) virus cannot be excluded, although the likelihood is low, based on the limited information obtained to date. It should be noted that human infection with A(H5N6) of related clade 2.3.4.4 has already occurred.” WHO: Assessment of risk associated with influenza A(H5N8) virus, 17 November 2016
    http://www.who.int/influenza/human_anim ... 201611/en/
  • Risk Estimation, Friedrich-Loeffler-Institut, 22 December 2016: "So far, no human cases of HPAIV H5N8 infection have been reported. Due to the genetic variability no reliable conclusions with regard to the virulence of the currently circulating pathogen are possible at present." https://www.fli.de/en/news/animal-disea ... nza-hpaiv/

WHO Public health advice

  • Avoid contact with any birds (poultry or wild birds) or other animals that are sick or are found dead and report them to the relevant authorities.
  • Wash hands properly with soap or a suitable disinfectant.
  • Follow good food safety and good food hygiene practices.
