Avian Influenza

This project focuses on tracking wild birds throughout Eurasia via satellite telemetry to better understand their spatiotemporal movement patterns, relationship to domestic birds, and potential role in the spread, persistence, and amplification of avian influenza viruses.

Understanding disease systems requires an understanding of the basic ecology of host species. USGS is involved in global efforts to explore the movements of bird species that are hosts of avian influenza as well as the potential impacts of changing landscapes on avian influenza.

USGS researchers are collaborating with partners around the globe to leverage new and existing telemetry data to answer broad scale questions about factors influencing avian movement and migration.

USGS is collaborating with numerous partner institutions to explore susceptibility and pathogenesis of relevant avian influenza strains in waterfowl species with special emphasis on sea ducks and diving ducks.

USGS researchers seek to understand the factors influencing the spread and persistence of avian influenza viruses on the landscape. This research also addresses how novel strains of highly pathogenic avian influenza are impacting a larger number and diversity of host species, including waterfowl, shorebirds, raptors and other birds.

USGS researchers are at the forefront of building and maintaining datasets that represent the spatial and temporal patterns in avian influenza virus prevalence in wild birds, which is critical information used to estimate transmission risk to domestic poultry.

USGS is creating spatially and temporally explicit inputs to improve avian influenza transmission risk modeling. This project places special emphasis on wild bird distribution and abundance models as well as avian influenza prevalence models.

USGS researchers are developing novel methods to improve our understanding of waterfowl distributions and abundance across the United States to inform a variety of ongoing disease studies. Understanding the distribution of wild waterfowl is a critical component to assessing avian influenza transmission risks across the landscape.

Recent outbreaks of highly pathogenic avian influenza have impacted a dramatically wider range of bird hosts than ever before. USGS researchers are working to identify which bird species have been exposed, which have developed immune responses, and how these species may influence viral ecology to inform risk management activities.

USGS researchers are using telemetry to improve our understanding of how wild birds move throughout their environments and the potential implications for disease transmission within and to domestic poultry.

Low pathogenic avian influenza (LPAI) viruses naturally occur in wild birds and are rarely fatal. Highly pathogenic avian influenza (HPAI) viruses are highly contagious, spread rapidly, are often fatal to poultry, and have been responsible for worldwide outbreaks. Together, LPAI and HPAI are generally referred to as either avian influenza viruses (AIVs) or "the bird flu."

This project focuses on understanding the forces driving the risk of avian influenza transmission from wild waterfowl to domestic poultry within the Chesapeake Bay region.
