Evidence of High Pathogenic Avian Influenza H5N1 Clade 2.3.4.4b Among Poultry in Ghana From 2021 to 2022. [PDF]

Vet Med Sci
Ghana experienced outbreaks of highly pathogenic avian influenza A H5N1 among poultry from 2021 to 2022. Analysing poultry, pigs, and environmental samples showed H5N1 prevalence of 2.36% (63/2640) among poultry only. The clade 2.3.4.4b virus showed mammalian adaptive motifs in haemagglutinin, emphasising the need for ongoing genomic surveillance among

Has Epizootic Become Enzootic? Evidence for a Fundamental Change in the Infection Dynamics of Highly Pathogenic Avian Influenza in Europe, 2021

mBio, 2022
Phylogenetic evidence from the recent resurgence of high-pathogenicity avian influenza (HPAI) virus subtype H5N1, clade 2.3.4.4b, observed in European wild birds and poultry since October 2021, suggests at least two different and distinct reservoirs.

Annual report on surveillance for avian influenza in poultry and wild birds in Member States of the European Union in 2022

EFSA Journal, 2023
All European Union (EU) Member States (MSs) are required to implement surveillance for avian influenza (AI) in poultry and wild birds and (i) to notify the outbreaks, when relevant and (ii) to report the results to the responsible authority. In addition,

High-pathogenicity avian influenza in wildlife: a changing disease dynamic that is expanding in wild birds and having an increasing impact on a growing number of mammals.

Journal of the American Veterinary Medical Association
While diverse strains of low-pathogenicity avian influenza have circulated in wild birds for a long period of time, there has previously been little pathology in wild birds, ducks have been the primary and largely asymptomatic wild reservoir, and ...

Ducks as Sentinels for Avian Influenza in Wild Birds

Emerging Infectious Diseases, 2009
To determine the effectiveness of ducks as sentinels for avian influenza virus (AIV) infection, we placed mallards in contact with wild birds at resting sites in Germany, Austria, and Switzerland. Infections of sentinel birds with different AIV subtypes confirmed the value of such surveillance for AIV monitoring.

Risk factors for avian influenza in Danish poultry and wild birds during the epidemic from June 2020 to May 2021

Frontiers in Veterinary Science
Exploring the risk factors of avian influenza (AI) occurrence helps us to monitor and control the disease. Since late 2020, the number of avian influenza outbreaks in domestic and wild birds has increased in most European countries, including Denmark ...
