Book (stand-alone)One Health High-Level Expert Panel Annual Report 2023 2024
Also available in:
No results found.This report summarizes the activities and results achieved in 2023 by the 26 experts of the One Health High-Level Expert Panel (OHHLEP). The first term of OHHLEP, initially set to expire in June 2023, was extended until December 2023 to allow for the completion of remaining deliverables and for the preparation for a second Term of OHHLEP by the Quadripartite. The Quadripartite updated the OHHLEP Terms of Reference for a second two-year term to focus on the implementation of the One Health approach and the One Health Joint Plan of Action (OH JPA) and launched a call for expressions of interest to renew the membership of the OHHLEP. -
Book (stand-alone)One Health High-Level Expert Panel Annual Report 2022 2023
Also available in:
No results found.This report summarizes the activities and results achieved in 2022 by the 26 experts of the One Health High-Level Expert Panel (OHHLEP). OHHLEP provided scientific advice on the Quadripartite One Health Joint Plan of Action (OH JPA) which was launched in October 2022, worked on a One Health Theory of Change that became an integral part of the OH JPA, prepared scientific opinions related to the envisaged Pandemic Instrument, and developed a white paper on the definition for the Prevention of zoonotic spillover. OHHLEP also continued to support the implementation of the Quadripartite OH JPA through development of an inventory of One Health tools. With these activities, OHHLEP supported the Quadripartite’s efforts on the mainstreaming and implementation of One Health. The report highlights main outputs and deliverables produced over the period and outlines priorities for 2023. -
BookletUpdated joint FAO/WHO/WOAH public health assessment of recent influenza A(H5) virus events in animals and people
Assessment based on data as of 18 November 2024
2024Also available in:
No results found.During 2020, high pathogenicity avian influenza (HPAI) A(H5N1) clade 2.3.4.4b viruses arose from previously circulating influenza A(H5Nx) viruses and spread predominantly via migratory birds to many parts of Africa, Asia and Europe. This epizootic event has led to unprecedented numbers of deaths in wild birds and caused outbreaks in poultry. In late 2021, these viruses crossed the Atlantic Ocean to North America and subsequently reached South America in October 2022. Over the past few years, there have been increased detections of A(H5N1) viruses in non-avian species globally including wild and domestic (companion and farmed) terrestrial and marine mammals, with recent cases in livestock in the United States of America. The majority of A(H5N1) viruses characterized genetically since 2020 belong to the haemagglutinin (HA) H5 clade 2.3.4.4b, with some regional exceptions. Since the last joint assessment of August 2024, at least 33 additional human cases of infection with A(H5) viruses have been reported. Of these, 30 were reported from the USA.FAO, WHO, and WOAH jointly updated their assessment of the risk of zoonotic transmission (i.e., animal to human) considering additional information made available since the previous assessment of 14 August 2024. This update is limited to the inclusion of additional information being made available globally. Due to the potential risk to human health and the far-reaching implications of the disease on the health of wild bird and other animal populations, the use of a One Health approach is essential to tackle avian influenza effectively, to monitor virus circulation, to prevent within species transmission and to prevent human infections from exposure to animals.
