Integrated Genomic and Epidemiological Surveillance to Monitor SARS‐CoV‐2 Variants in Italy: Insights From the JN.1 Case Study (2023–2024)

Journal of Medical Virology, Volume 98, Issue 1, January 2026.
ABSTRACT The epidemiology of SARS‐CoV‐2 is marked by the continuous emergence of new lineages. Early detection and assessment of their transmissibility can be challenging for surveillance systems that rely solely on case time series data. Genomic surveillance, focusing on identifying and characterizing circulating variants, can provide early insights ...

Intra- and inter-host origin, evolution dynamics and spatial-temporal transmission characteristics of circoviruses

Frontiers in Immunology
IntroductionSince their identification in 1974, circoviruses have caused clinicopathological diseases in various animal species, including humans. However, their origin, transmission, and genetic evolution remain poorly understood.MethodsIn this study ...

Trends of influenza B during the 2010–2016 seasons in 2 regions of north and south Italy: The impact of the vaccine mismatch on influenza immunisation strategy [PDF]

, 2018
Influenza A and B viruses are responsible for respiratory infections, representing globally seasonal threats to human health. The 2 viral types often co-circulate and influenza B plays an important role in the spread of infection.

Prevalence and Heterogeneity of Swine Influenza Virus in China From 2010 to 2025: A Systematic Review and Meta‐Analysis

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Background Swine influenza virus (SIV) is endemic in China, threatening the swine industry and public health. This meta‐analysis estimated the national pooled prevalence of SIV (2010–2025) and identified key sources of heterogeneity. Methods Following Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines, six databases ...

Evolutionary Analysis of a Parrot Bornavirus 2 Detected in a Sulphur-Crested Cockatoo (Cacatua galerita) Suggests a South American Ancestor

Animals, 2023
Parrot bornavirus (PaBV) is an RNA virus that causes Proventricular Dilatation Disease (PDD), neurological disorders, and death in Psittaciformes. Its diversity in South America is poorly known. We examined a Cacatua galerita presenting neuropathies, PDD,

Rapid Spread of Novel Infectious Bursal Disease Virus Variant (Genotype A2dB1b) in the Near East and Persian Gulf Regions: Molecular Surveillance and Phylodynamic Reconstruction

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Infectious bursal disease virus (IBDV) is one of the most impactful pathogens of poultry, with disease manifestations ranging from acute forms to subclinical but immunosuppressive infections. This heterogeneity, accompanied by a significant antigenic variability, is sustained by high mutation rates and frequent reassortments between the two genome ...

Host-pathogen evolutionary signatures reveal dynamics and future invasions of vampire bat rabies [PDF]

, 2016
Anticipating how epidemics will spread across landscapes requires understanding host dispersal events that are notoriously difficult to measure. Here, we contrast host and virus genetic signatures to resolve the spatiotemporal dynamics underlying ...

VirPhyKit: An Integrated Toolkit for Viral Phylogeographic Analysis

Ecology and Evolution, Volume 15, Issue 12, December 2025.
A new toolkit for phylogeographic analysis called VirPhyKit is developed. The toolkit integrates 12 specialized modules within an intuitive point‐and‐click interface, streamlining key tasks such as sequence curation, spatiotemporal subsampling, migration pattern analysis, and molecular dating. ABSTRACT The evolutionary, demographic, and phylogeographic
