Transmission dynamics of highly pathogenic avian influenza among multiple waterfowl species and backyard poultry: the impact of the stopover period

Scientific Reports
Spillover of Highly Pathogenic Avian Influenza (HPAI) to backyard poultry via migratory birds threatens the poultry industry and public health. To improve the understanding of spillover events, we developed a stochastic compartmental mathematical model ...

Genomic characterization of highly pathogenic H5 avian influenza viruses from Alaska during 2022 provides evidence for genotype-specific trends of spatiotemporal and interspecies dissemination

Emerging Microbes and Infections
The ongoing panzootic of highly pathogenic H5 clade 2.3.4.4b avian influenza (HPAI) spread to North America in late 2021, with detections of HPAI viruses in Alaska beginning in April 2022.

Avian influenza overview November 2018 – February 2019

EFSA Journal, 2019
No human infections due to highly pathogenic avian influenza (HPAI) A(H5N8) or A(H5N6) viruses ‐ detected in wild birds and poultry outbreaks in Europe ‐ have been reported so far and the risk of zoonotic transmission to the general public in Europe is ...

Phylodynamics of H5N1 Highly Pathogenic Avian Influenza in Europe, 2005-2010: Potential for Molecular Surveillance of New Outbreaks. [PDF]

, 2015
Previous Bayesian phylogeographic studies of H5N1 highly pathogenic avian influenza viruses (HPAIVs) explored the origin and spread of the epidemic from China into Russia, indicating that HPAIV circulated in Russia prior to its detection there in 2005 ...

HPAI transmission dynamics in endemic settings

, 2023
Transaction dynamics in poultry value chains are influenced by factors such as lim-ited access to financial capital, leading to potential adoption of risky practices (e.g. in Bangladesh). The degree to which HPAI transmission and endemicity is influ-enced by multiple practices across farming and trading systems, including density, connectivity ...

Adoption of HPAI biosecurity measures: The Chinese broiler industry

Journal of Integrative Agriculture, 2017
Highly pathogenic avian influenza (HPAI) contamination via wild birds and rodents poses a threat to food security and safety. As chicken meat comprises an increasing proportion of diet in China, it is useful to determine whether broiler farmers are adopting wild bird and rodent controls to minimize the risk of HPAI impacts on food supply.

One-way trip: Influenza virus' adaptation to gallinaceous poultry may limit its pandemic potential [PDF]

, 2014
We hypothesise that some influenza virus adaptations to poultry may explain why the barrier for human-to-human transmission is not easily overcome once the virus has crossed from wild birds to chickens.

Factors Determining Farmers’ Decision on Highly Pathogenic Avian Influenza Vaccination at the Small Poultry Farms in Western Java

Media Peternakan, 2011
Vaccination of highly pathogenic avian influenza (HPAI) is one of the control measures in poultry farm. There are several factors determining farmer’s decision on the implementation of this vaccination.
