In the last 30 days, 66 poultry flocks have been affected, leading to the culling of over 3.5 million turkeys, chickens, and ducks. This represents an increase compared to the summer months. The virus can spread from infected wild birds to commercial or backyard flocks.
Current outbreaks are concentrated in the central U.S., with scientists anticipating further spread due to bird migratory patterns.
Concerns have been raised about potential human infections. The U.S. reported nearly 70 human cases, including one fatality, in the previous year. No human cases have been reported since early this year. Scientists indicate that the potential for human infections remains.
Federal Response and Monitoring
Scientists tracking the H5N1 virus have reported reduced visibility into its activity in both animal and human populations. This is attributed to scaled-back federal surveillance and communication efforts.
A network of influenza researchers previously maintained consistent contact with federal health agencies regarding H5N1, coordinating research priorities and discussing viral changes. This infrastructure is described as being
