Serological Surveillance of Avian Influenza Virus Exposure Using Paired Sera Among Occupational Contacts in Taiwan, January–September 2025

Influenza and Other Respiratory Viruses, Volume 20, Issue 7, July 2026.
ABSTRACT In 2025, Taiwan implemented paired sera surveillance among occupational contacts of avian influenza viruses (AIVs). Of 122 contacts analyzed, 117 (95.9%) remained asymptomatic with high personal protective equipment compliance (91.8%). No seroconversion was detected against AIV A(H5N2) clade 2.3.4.4b. These findings suggest a low risk of human

Predicting Hotspots for Influenza Virus Reassortment

Emerging Infectious Diseases, 2013
The 1957 and 1968 influenza pandemics, each of which killed ≈1 million persons, arose through reassortment events. Influenza virus in humans and domestic animals could reassort and cause another pandemic.

Heterosubtype neutralizing responses to influenza A (H5N1) viruses are mediated by antibodies to virus haemagglutinin. [PDF]

PLoS ONE, 2009
BACKGROUND:It is increasingly clear that influenza A infection induces cross-subtype neutralizing antibodies that may potentially confer protection against zoonotic infections. It is unclear whether this is mediated by antibodies to the neuraminidase (NA)

Isolation and characterization of highly pathogenic avian influenza virus subtype H5N1 from donkeys [PDF]

Journal of Biomedical Science, 2010
The highly pathogenic H5N1 is a major avian pathogen that crosses species barriers and seriously affects humans as well as some mammals. It mutates in an intensified manner and is considered a potential candidate for the possible next pandemic with all the catastrophic consequences.Nasal swabs were collected from donkeys suffered from respiratory ...

Contribution of E190D and Q226H Mutations in HA to the Receptor‐Binding Profile of D1.1 Genotype H5N1 Viruses

Influenza and Other Respiratory Viruses, Volume 20, Issue 7, July 2026.
ABSTRACT A 2024 human HPAI H5N1 case in British Columbia showed mixed viral populations containing HA‐190D (28%) and HA‐226H (35%) variants in tracheal aspirate sequencing. In this study, solid‐phase binding assay and molecular docking were used to evaluate the contribution of HA‐E190D/Q226H mutations to the viral receptor profiles.

Continuing Threat of Influenza (H5N1) Virus Circulation in Egypt

Emerging Infectious Diseases, 2011
Reservoirs for the continuing influenza (H5N1) outbreaks in Egypt are ill-defined. Through active surveillance, we detected highly pathogenic influenza subtype H5 viruses in all poultry sectors; incidence was 5%. No other subtypes were found.

Avian influenza overview March–May 2026

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract Between 28 February and 4 June 2026, 949 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (186) and wild (763) birds in 30 countries in Europe. The downward trend in the number of detections observed at the end of the previous reporting period continued and is expected to persist throughout the summer ...

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)
