    Controlling highly pathogenic avian influenza outbreaks in Ghana-TCP/GHA/3505 2017
    Also available in:

    Livestock and poultry-keeping are crucial to the farming and livelihood systems of Ghana. In May 2015, outbreaks of highly pathogenic avian influenza (HPAI) threatened these systems and made it essential that measures be put in place to forestall losses caused by the disease in the affected areas and elsewhere. The project was designed to control the disease in Ghana and, above all, to prevent its spread to non-affected regions of the country and to neighbouringcountries, by means of an immediat e response.

    Estimates of global HPAI loss from the outbreaks since 2003 run into billions1. The cost of the 1997 outbreak in Hong Kong, it is suggested, may have been US$100s of millions including knock on effects, but the very strict control measures applied may have prevented large scale human infection. In spite of this, the global poultry sector is dynamic and resilient. Global production and trade have shown the potential to recover quickly from severe outbreaks that until recently were confine d mainly to East and South East Asia. Why, then, is this disease the focus of so much attention, when other major transboundary animal diseases (classical swine fever, even foot and mouth disease) and other important diseases of poultry (Newcastle disease) cause much less interest.?

    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.
