Estimation of the Basic Reproduction Numbers of the Subtypes H5N1, H5N8, and H5N6 During the Highly Pathogenic Avian Influenza Epidemic Spread Between Farms

Frontiers in Veterinary Science, 2021
It is important to understand pathogen transmissibility in a population to establish an effective disease prevention policy. The basic reproduction number (R0) is an epidemiologic parameter for understanding the characterization of disease and its ...

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.

Serological Surveillance of Avian Influenza Virus Exposure Using Paired Sera Among Occupational Contacts in Taiwan, January–September 2025

Influenza and Other Respiratory Viruses, Volume 20, Issue 7, July 2026.
ABSTRACT In 2025, Taiwan implemented paired sera surveillance among occupational contacts of avian influenza viruses (AIVs). Of 122 contacts analyzed, 117 (95.9%) remained asymptomatic with high personal protective equipment compliance (91.8%). No seroconversion was detected against AIV A(H5N2) clade 2.3.4.4b. These findings suggest a low risk of human
