Avian influenza overview June–August 2026

EFSA Journal, Volume 24, Issue 9, September 2026.
Abstract Between 5 June and 28 August 2026, 110 highly pathogenic avian influenza (HPAI) A(H5N1) virus detections were reported in domestic (7) and wild (103) birds in 12 countries in Europe. The number of detections remained at a seasonal low throughout the summer, continuing the decline observed since spring.

Genomic and Clinicopathological Characterization of a Reassortant HPAI H5N1 (Clade 2.3.4.4b) in an Endangered Cinereous Vulture (Aegypius monachus) in South Korea, 2026

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Clade 2.3.4.4b highly pathogenic avian influenza viruses (HPAIVs) continue to circulate widely in East Asia and undergo frequent reassortment in wild birds. Raptors are regarded as spillover hosts that may be exposed through predation or scavenging, yet integrated clinicopathologic and genomic investigations in cinereous vultures remain limited.

From Clustered to Sporadic: Structural Shifts in the Spatiotemporal Dynamics of HPAI Following the 2017 Policy Reinforcement in South Korea (2003–2025)

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Highly pathogenic avian influenza (HPAI) is a devastating viral disease causing substantial economic losses in the poultry industry and posing potential zoonotic risks. Located along the East Asian–Australasian Flyway (EAAF), South Korea has experienced recurrent outbreaks of HPAI since 2003.

Assessing potential pathogenicity of novel highly pathogenic avian influenza (H5N6) viruses isolated from Mongolian wild duck feces using a mouse model

Emerging Microbes and Infections, 2022
Several novel highly pathogenic avian influenza (HPAIVs) A(H5N6) viruses were reported in Mongolia in 2020, some of which included host-specific markers associated with mammalian infection. However, their pathogenicity has not yet been investigated. Here,

Novel H5N6 reassortants bearing the clade 2.3.4.4b HA gene of H5N8 virus have been detected in poultry and caused multiple human infections in China

Emerging Microbes and Infections, 2022
The globally circulating H5N8 avian influenza viruses bearing the clade 2.3.4.4b hemagglutinin (HA) gene are responsible for the loss of more than 33 million domestic poultry since January 2020. Moreover, the H5N8 viruses have reassorted with other avian

A Multi‐Reassortant H3N8 Avian Influenza Virus Derived From Migratory Birds in Eastern China Exhibits Cross‐Species Transmission Potential

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Migratory birds are one of the main reservoirs and long‐distance transmission vectors of avian influenza viruses (AIVs). A migratory‐bird‐origin H3N8 subtype AIV (A/wild bird/Huadong/sy17/2024, hereafter named as WD/HDsy17/24) was isolated and identified in Jiangsu Province, Eastern China, in 2024.

Unveiling Novel Viral Diversity, Biogeography, and Host Networks in Wildlife Through High‐Throughput Sequencing Data Mining

Advanced Science, Volume 12, Issue 46, December 11, 2025.
Analysis of 57 536 high‐throughput sequencing datasets uncovers a vast, hidden world of viruses in wildlife. The researchers reveal significant geographic and host‐specific patterns of viruses, and their surprising cross‐species transmissions, such as avian flu viruses infecting goats.

Spatial Patterns of Global Peste Des Petits Ruminants Virus and Its Potential Risk Assessment for Various Wildlife Habitats

Ecology and Evolution, Volume 15, Issue 12, December 2025.
This study found that according to the analysis of PPR epidemic data from 2007 to 2024, the driving mechanism of key climatic and environmental factors such as temperature seasonality (standard deviation × 100) (Bio4), annual mean temperature (Bio1), isothermality (Bio3), mean diurnal range (Bio2), mean monthly precipitation in March (Prec3), and the ...
