    Emergency Assistance to Enhance Preparedness for Highly Pathogenic Avian Influenza (HPAI) Outbreak in Ukraine - TCP/UKR/3802 2024

    In late July 2020, both the Russian Federation and Kazakhstan began documenting outbreaks of highly pathogenic avian influenza (HPAI) caused by the H5 virus strain in domestic fowl and wild birds near their shared border. The infection subsequently spread across the region via a number of migratory routes of wild birds, resulting in the identification of H5N8 HPAI cases in Western Europe, East Asia, the Middle East, and Africa by early November 2020. By May 2021, around 3 000 occurrences of HPAI had been documented across approximately 50 countries in Europe, Asia, and Africa. The H5N8 avian influenza (AI) virus, along with other H5Nx clade 2.3.4.4b viruses, exhibits strong adaptation to both fowl and different species of wild birds. Notably, the H5N8 AI virus has led to seven cases of asymptomatic human infections in the Russian Federation, underscoring its potential for zoonotic transmission. Moreover, in July 2021, the Russian Federation notified the World Organisation for Animal Health (OIE) regarding significant pelican mortality in Central Siberia. Experts interpreted this event as a clear indicator of what could potentially occur in Europe during the autumn migration, starting from late August 2021.

    2016–2018 Spread of H5N8 highly pathogenic avian influenza (HPAI) in sub-Saharan Africa
    Epidemiological and ecological observations
    2018

    South Africa is experiencing an epidemic of H5N8 HPAI virus since 2017 in both domestic and wild birds. The document will assess the potential for the virus to persist in this ecosystem and potentially spread northwards with wild bird movement during the South African winter (i.e. June – September 2018).

    Global consultation on highly pathogenic avian influenza (HPAI)

    Highly pathogenic avian influenza (HPAI) is a severe and highly contagious disease that has severe impacts on animal and human health, livelihoods, and the economy. At the time of the consultation, the recent panzootic had affected more than 70 countries and territories, resulting in over 11 000 disease events in both wild and domestic bird populations. The disease has also spilled over to several mammalian species, including humans, and may result in severe ecological and biodiversity consequences. Considering the alarming spread of HPAI and the evolution of avian influenza in wild birds, The Food and Agricultural Organization (FAO) and Network of Expertise on Animal Influenza (OFFLU) brought together the global scientific community to review the latest science and evidence on the disease, to support development/implementation of disease prevention and control strategies and policies and contribute to global efforts towards reducing pandemic risk. The report summarizes the meeting discussions, and key recommendations to reduce the transmission of HPAI along the poultry value chains, and the spillover risk to humans and wildlife. The meeting report will contribute to revising the FAO-WOAH global control strategy for HPAI and developing evidence-based policies and research agendas to tackle the disease. Sharing the meeting report with technical experts and policy makers will help support the development of a research and development agenda to tackle HPAI globally.
