A Retrospective Cross-Sectional Study (2009-2023): Exploring Influenza A(H1N1)pdm09 Antibody Time Series in Humans and Swine and Vaccine Coverage in Two Target Groups. [PDF]

Zoonoses Public Health
ABSTRACT Introduction Swine may act as ‘epidemiological bridges’ and reservoirs for the emergence of novel zoonotic influenza viruses with pandemic potential. While bidirectional exchange of influenza A viruses at the swine–human interface is well recognised, data on the extent of interspecies transmission are limited.
