Avian Influenza H5N8 – Global situation update, as of 06 June 2018


The next update will be issued on 04 July 2018.


Information provided herein is current as of the date of issue. Information added or changed since the last H5N8 situation update appears in red. Human cases are depicted in the geographic location of their report. For some cases, exposure may have occurred in one geographic location but reported in another. For cases with unknown onset date, reporting date was used instead. FAO compiles information drawn from multiple national (Ministries of Agriculture or Livestock, Ministries of Health, Provincial Government websites; Centers for Disease Prevention and Control [CDC]) and international sources (World Health Organization [WHO], World Organisation for Animal Health [OIE]) as well as peer-reviewed scientific articles. FAO makes every effort to ensure, but does not guarantee, accuracy, completeness or authenticity of the information. The designation employed and the presentation of material on the map do not imply the expression of any opinion whatsoever on the part of FAO concerning the legal or constitutional status of any country, territory or sea area, or concerning the delimitation of frontiers.

Low- and High-Pathogenic Avian Influenza H5 and H7 Spread Risk Assessment Within and Between Australian Commercial Chicken Farms. Frontiers in Veterinary Science, 5, 63. http://doi.org/10.3389/fvets.2018.00063. [reference].
    • This study quantified and compared the probability of avian influenza spread within and between Australian commercial chicken farms via specified spread pathways using scenario tree mathematical modeling. Outputs indicate that the probability of no establishment of infection in a shed is the most likely end-point after exposure and infection of low-pathogenic avian influenza (LPAI) in one chicken for all farm types.

    • The present study aimed to perform a comparative analysis of new HPAIV A(H5N8) strains isolated in the Russian Federation. Phylogenetic analysis revealed four genetically distinct subgroups in HPAIV A(H5N8) from the 2016-2017 season.

    • In this study, the authors evaluated the pathogenicity, infectivity and transmissibility of an H5N8 HPAI clade virus in Northern Pintails and compared the results to that of an H5N1 HPAI clade virus. The H5N8‐infected birds shed high virus titres from oropharynx and cloaca, which in the field supported virus transmission and spread.

    • In this study the authors collected AIV samples from various duck and gull species that breed, migrate and overwinter in Georgia, for six consecutive years (2010-2016). They found substantial subtype diversity of viruses that varied in prevalence from year to year, including H5N5 and H5N8 HPAIVs belonging to clade
