This was reported to the World Organization for Animal Health (WOAH) per protocol and published on January 24, 2025.<\/p>\n\n\n\n<p>This finding is not unexpected or alarming since ducks serve as a reservoir host for influenza A viruses and there is evidence that the H5N9 virus is a North American N9&nbsp;reassortant of the H5N1 virus that has been seen in wild birds since 2022 with periodic spillover into domestic flocks. The California Department of Food and Agriculture (CDFA)&nbsp;and USDA remain vigilant for any H5 viruses and will continue to monitor for new or unusual viruses as our on-going testing strategy.<\/p>\n\n\n\n<p><strong>Currently, there is no additional information to indicate that this reassortant\/strain H5N9 presents any increased risk to public health.&nbsp;<\/strong>There is still no known human-to-human&nbsp;transmission of the bird flu virus.
