Genetic Diversity and Biological Characteristics of H3 Avian Influenza Virus Isolated from China in 2021–2022 Showed the Emerging H3N8 Posed a Threat to Human Health

<div>Replication of H3 viruses in chickens. Viral titers in the organs of chickens after inoculation with 10<sup>6</sup> EID<sub>50</sub> of different viruses. Three chickens from each group were euthanized at 3 dpi, and the viral titers in their organs were determined in eggs. Dashed lines indicate the lower limit of virus detection.</div>
