Explosive geographical expansion of the avian influenza virus (AIV) continues to threaten human and animal health during and after the COVID-19 pandemic. Individuals from 17 countries across five continents have been infected by the five emerging (H5N8, H10N3, H3N8, H10N5, and H5N2) and four re-emerging (H5N1, H5N6, H7N9, and H9N2) subtypes of AIV since 2019 (appendix). H5N1 viruses, especially those of clade 2.3.4.4b, continue to diversify genetically, spread geographically, and infect humans, as illustrated by the first ever human infection in Victoria, Australia,1Department of Health.

Moreover, high viral concentrations have been detected in unpasteurised milk from infected dairy cattle. A comprehensive sequence-based analysis suggested that the viruses isolated from wild birds, cows, cats, and humans in Texas during March, 2024, share the same origin, ie, infected migratory wild birds.3Hu X Saxena A Magstadt DR et al.Highly pathogenic avian influenza A ...
