Phylodynamic analysis of a viral infection network [PDF]

Frontiers 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.

Feathers and flu: identifying data gaps in avian influenza host dynamics to prioritize wildlife conservation Plumas y gripe: identificación de datos faltantes en la dinámica de hospedadores de la influenza aviar para priorizar la conservación de la vida silvestre

Wildlife Monographs, Volume 225, Issue 1, September 2026.
We describe the host response continuum for highly pathogenic avian influenza viruses (HPAIV), including the continuum of host responses to HPAIV infection and exposure based on the primary axis of host competence, ability to infect other hosts, and host vulnerability.

Phylodynamics and movement of Phycodnaviruses among aquatic environments [PDF]

, 2011
Phycodnaviruses have a significant role in modulating the dynamics of phytoplankton, thereby influencing community structure and succession, nutrient cycles and potentially atmospheric composition because phytoplankton fix about half the carbon dioxide ...

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,

Epidemiology, Genomic Diversity, and Evolutionary Dynamics of Human Metapneumovirus Over 7 Years of Integrated Community‐ and Hospital‐Based Sentinel Surveillance in Senegal, 2018–2024

Influenza and Other Respiratory Viruses, Volume 20, Issue 7, July 2026.
ABSTRACT Background In late 2024, a major human metapneumovirus (HMPV) outbreak in China caused widespread pneumonia and thousands of hospitalizations, drawing global attention to this virus. In Senegal, a concomitant rise in HMPV detections was observed in both community and hospital settings.

Dynamics of HIV-1 Molecular Networks Reveal Effective Control of Large Transmission Clusters in an Area Affected by an Epidemic of Multiple HIV Subtypes

Frontiers in Microbiology, 2020
This study reconstructed molecular networks of human immunodeficiency virus (HIV) transmission history in an area affected by an epidemic of multiple HIV-1 subtypes and assessed the efficacy of strengthened early antiretroviral therapy (ART) and regular ...

Foodborne Risk to Human Health of Hepatitis E Virus in Pigs and Pigmeat in Ireland

Food Risk Assess Europe, Volume 4, Issue 3, July 2026.
Abstract Hepatitis E virus (HEV) is a major cause of acute viral hepatitis in people worldwide. In Ireland, evidence of past HEV exposure has been identified in approximately 5% of blood donors, while a small proportion have detectable viral RNA. HEV is also present in pigs and has been detected in pigmeat products, raising concerns about foodborne ...

Retroviral Phylodynamics

, 2020
Washington, DC is experiencing a generalized HIV-1 epidemic, defined by the World Health Organization as affecting >1% of the population, despite recent reductions in HIV-1 from 2.5% in 2013 to 1.9% in 2016 and 2017.

Phylodynamic and Phylogeographic Analysis of Hepatitis Delta Virus Genotype 3 Isolated in South America

Viruses, 2019
The hepatitis delta virus (HDV) is a globally distributed agent, and its genetic variability allows for it to be organized into eight genotypes with different geographic distributions.

In Search of Covariates of HIV-1 Subtype B Spread in the United States—A Cautionary Tale of Large-Scale Bayesian Phylogeography

Viruses, 2020
Infections with HIV-1 group M subtype B viruses account for the majority of the HIV epidemic in the Western world. Phylogeographic studies have placed the introduction of subtype B in the United States in New York around 1970, where it grew into a major ...
