Abstract Summary

A national survey of 800 poultry flocks in Tunisia found 28.7% tested positive for influenza A virus antibodies, with H9N2 subtype identified. Higher infection rates occurred in coastal areas, during autumn/winter, and in farms with poor biosecurity. Genetic analysis revealed mutations in viral proteins, suggesting ongoing evolution that could lead to more dangerous strains. Enhanced biosecurity and vaccination are recommended.
