Molecular surveillance confirms absence of avian influenza virus type A in Ecuadorian poultry: A retrospective reverse transcription quantitative polymerase chain reaction study from April 2023 to June 2024 [PDF]

Veterinary World
Background and Aim: Avian influenza (AI) is a highly contagious zoonotic disease affecting birds and, occasionally, humans. Ecuador confirmed its first case of AI in late 2022, resulting in significant avian mortality and economic losses.

Determining the Environmental and Ecological Factors Associated With Poultry Farm Spillover of Highly Pathogenic Avian Influenza (H5N1) in British Columbia, Canada

Zoonoses and Public Health, EarlyView.
ABSTRACT Introduction Highly pathogenic avian influenza (HPAI) H5N1, clade 2.3.4.4b is a global threat causing widespread outbreaks on poultry farms and high mortality among wild bird populations in Canada. Wild aquatic birds are generally recognised as key reservoir hosts for avian influenza viruses (AIV's).

RNF213 Is an Interferon‐Stimulated Gene That Targets Influenza A Virus NP and Activates MDA5 to Restrict Infection

Advanced Science, Volume 13, Issue 31, 4 June 2026.
RNF213 is characterized as a dual‐functional antiviral effector. It directly mediates the degradation of the influenza A virus nucleoprotein (NP) while simultaneously activating the MDA5‐mediated innate immune signaling pathway. This coordinated response establishes a powerful host defense system against viral infection. ABSTRACT Influenza A virus (IAV)

H5N1 Avian Influenza in Children [PDF]

Clinical Infectious Diseases, 2012
Avian influenza continues to pose a threat to humans and maintains the potential for greater transmissibility. Understanding the clinical presentation and prognosis in children will help guide effective diagnosis and treatment.A global patient registry was created to enable systematic collection of clinical, exposure, treatment, and outcomes data on ...

Beyond birds: rethinking bird‐centered pathogen models in light of insect migration

Ecography, Volume 2026, Issue 6, June 2026.
Migration redistributes biomass, nutrients, and pathogens across ecosystems. For decades, migratory birds have been treated as the default long‐distance pathogen vectors, shaping both conceptual frameworks and empirical models of disease ecology.

H5N1 Clade 2.2 Polymorphism Tracing Identifies Influenza Recombination and Potential Vaccine Targets

, 2007
Highly pathogenic Influenza A H5N1 was first identified in Guangdong Province in 1996, followed by human cases in Hong Kong in 1997 1. The number of confirmed human cases now exceeds 300 and the associated Case Fatality Rate exceeds 60% 2.

Extralimital records of the Macaroni Penguin in East Antarctica at multiple locations during the molting season

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract Macaroni Penguins (Eudyptes chrysolophus) are abundant across sub‐Antarctic islands but occur only rarely in East Antarctica. Here, we report three concurrent extralimital records of Macaroni Penguins well south of their typical distribution during the austral summer of 2023–2024.

Discordant correlation between serological assays observed when measuring heterosubtypic responses against avian influenza H5 and H7 viruses in unexposed individuals [PDF]

, 2014
The human population is constantly exposed to multiple influenza A subtypes due to zoonotic spill over and rapid viral evolution driven by intrinsic error-prone replication and immunological pressure.
