Host Species Contribution to the Spatiotemporal Dynamics of the 2024–2025 H5N1 Epidemic in Italy

open access: yesInfluenza and Other Respiratory Viruses, Volume 20, Issue 6, June 2026.
ABSTRACT This study uses a phylodynamic approach to investigate host species contribution in the spatiotemporal dynamics of the highly pathogenic avian influenza A(H5N1) viruses of clade 2.3.4.4b identified during the 2024–2025 epidemic in Italy.

Phylodynamics of viral infections

open access: yes, 2017
Phylodynamics is a recent field that aims at using genetic sequence data to estimate epidemiological parameters such as the viral population growth rate, the number of infections in the population or even their duration. Its main underlying assumption is that the way viruses spread leaves marks in their genome.

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

open access: yesFrontiers 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 ...

Unraveling the Transmission Dynamics of a Novel Norovirus GII.17[P17] Lineage During Two Consecutive Outbreaks in a Spanish Hospital

open access: yesJournal of Medical Virology, Volume 98, Issue 5, May 2026.
ABSTRACT Norovirus outbreaks in healthcare settings pose significant challenges to infection prevention and control (IPC). To prevent and control such outbreaks efficiently, identifying sources and transmission clusters (TCs) is crucial but often limited by traditional outbreak investigations.

Phylodynamics of the HIV-1 Epidemic in Cuba

open access: yesPLoS ONE, 2013
Previous studies have shown that the HIV-1 epidemic in Cuba displayed a complex molecular epidemiologic profile with circulation of several subtypes and circulating recombinant forms (CRF); but the evolutionary and population history of those viral variants remains unknown.

Expanded Genomic Surveillance and Seasonal Comparisons of Human Respiratory Syncytial Virus Infections in Minnesota, USA, 2023–2025

open access: yesInfluenza and Other Respiratory Viruses, Volume 20, Issue 5, May 2026.
ABSTRACT Background Human respiratory syncytial virus (HRSV) imposes a substantial burden in the United States. The use of whole‐genome sequencing (WGS) for public health surveillance of HRSV lags that for other viral pathogens. The objective of this study was to expand the scope and depth of WGS‐based surveillance of HRSV in Minnesota, USA.

Phylodynamic analysis of a viral infection network [PDF]

open access: yesFrontiers in Microbiology, 2012
Viral infections by sexual and droplet transmission routes typically spread through a complex host-to-host contact network. Clarifying the transmission network and epidemiological parameters affecting the variations and dynamics of a specific pathogen is a major issue in the control of infectious diseases.

Emergence and Rapid Spread of a New Reassortant High Pathogenicity H5N1 Clade 2.3.4.4b Avian Influenza Virus in Nigeria

open access: yesInfluenza and Other Respiratory Viruses, Volume 20, Issue 5, May 2026.
ABSTRACT Over the past two decades, West Africa has experienced recurrent incursions of Goose/Guangdong‐lineage highly pathogenic avian influenza (HPAI) A(H5N1), with Nigeria as a hotspot for repeated introductions and sustained circulation. Since 2021, European‐origin clade 2.3.4.4b H5Nx genotypes, particularly EA‐2020‐C, have predominated in regional

Origin and Phylodynamics of Rabbit Hemorrhagic Disease Virus [PDF]

open access: yesJournal of Virology, 2009
ABSTRACT To determine the origin, phylogenetic relationships, and evolutionary dynamics of rabbit hemorrhagic disease virus (RHDV), we examined 210 partial and complete capsid gene nucleotide sequences. Using a Bayesian Markov chain Monte Carlo approach, we estimated that these sequences evolved at a rate of 3.9 × 10 −

Molecular Basis of the Toxigenic Vibrio cholerae O1 Serotype Switch from Ogawa to Inaba in Haiti

open access: yesMicrobiology Spectrum, 2023
Toxigenic Vibrio cholerae O1 serotype Ogawa was introduced involuntarily into Haiti in October 2010, and virtually all of the clinical strains isolated during the first 5 years of the epidemic were Ogawa.
