Genetic Evolution of Avian Influenza A (H9N2) Viruses Isolated from Domestic Poultry in Uganda Reveals Evidence of Mammalian Host Adaptation, Increased Virulence and Reduced Sensitivity to Baloxavir

Viruses, 2022
A (H9N2) avian influenza A viruses were first detected in Uganda in 2017 and have since established themselves in live bird markets. The aim of this study was to establish the subsequent genetic evolution of H9N2 viruses in Uganda.

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

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
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

Rift Valley Fever Phlebovirus Reassortment Study in Sheep

Viruses
Rift Valley fever (RVF) in ungulates and humans is caused by a mosquito-borne RVF phlebovirus (RVFV). Live attenuated vaccines are used in livestock (sheep and cattle) to control RVF in endemic regions during outbreaks.

Waterfowl Move Less in Heterogeneous and Human‐Populated Landscapes, With Implications for Spread of Avian Influenza Viruses

Ecology Letters, Volume 29, Issue 1, January 2026.
We show that non‐migratory waterfowl movement distances are shorter in areas of high land cover heterogeneity and human population density, and that these movement distances are related to the spread of highly pathogenic avian influenza. These results suggest that habitat management could contribute to the spread of these viruses.

Organization of the Influenza A Virus Genomic RNA in the Viral Replication Cycle—Structure, Interactions, and Implications for the Emergence of New Strains

Pathogens, 2020
The influenza A virus is a human pathogen causing respiratory infections. The ability of this virus to trigger seasonal epidemics and sporadic pandemics is a result of its high genetic variability, leading to the ineffectiveness of vaccinations and ...

Influenza Surveillance in the Central African Republic From 2015 to 2018 to Inform Vaccination and Treatment Strategies

Influenza and Other Respiratory Viruses, Volume 20, Issue 1, January 2026.
ABSTRACT Background Surveillance of influenza infections and virus characterisation are essential to guide prevention strategies. In the Central African Republic (CAR), data on influenza viruses are patchy and poorly documented. Objective To study the clinical, seasonal, genetic and phenotypic characteristics of influenza viruses circulating in the CAR

Reverse Genetics System for Shuni Virus, an Emerging Orthobunyavirus with Zoonotic Potential

Viruses, 2020
The genus Orthobunyavirus (family Peribunyaviridae, order Bunyavirales) comprises over 170 named mosquito- and midge-borne viruses, several of which cause severe disease in animals or humans. Their three-segmented genomes enable reassortment with related

Epidemiology and Risk Modelling of Influenza A Virus Within and Between Pig Herds in Northern Lao PDR

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Animal‐origin influenza A virus (IAV) is a perennial candidate for causing the next pandemic. With high risk for interspecies IAV transmission but limited resources for surveillance, particularly in rural areas of low‐ and middle‐income countries (LMICs) such as Laos, there is a need to develop targeted, risk‐based strategies for early detection of ...
