The Emerging Threat of H5N1 to Human Health

This editorial explores the increasing concern over the spread of highly pathogenic avian influenza A(H5N1) in animals and humans. The authors discuss recent U.S. and Canadian cases, the roles of specific viral genotypes (notably B3.13 and D1.1), and key mutations potentially indicating increased virulence and human adaptation. The editorial emphasizes the importance of surveillance, data transparency, and collaboration across public health and veterinary sectors. It also examines vaccine development efforts, antiviral efficacy, and infection control strategies. While the overall public risk remains low, the authors stress the need for vigilant monitoring to mitigate the risk of wider transmission and to ensure preparedness.
