Avian Influenza

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.

This project focuses on improving our understanding of how current and previous infection with avian influenza viruses impact the movement ecology of wild bird species.

The Asian Flyways Collaborative for Waterbirds (AFCoW) is a collaborative group effort that brings together research scientists engaged in understanding waterbird ecology in Eastern Asia. Due to the complexity of waterbird biology and unique threats to their populations in East Asia, we have established a voluntary international network of collaborators to promote advanced studies of large-scale...

Avian influenza virus in the aquatic environment: Surveillance in waterfowl habitat on the Delmarva Peninsula.

This project seeks to improve our understanding of how domestic ducks move throughout the market chain in China and the role this may play in the amplification and spread of avian influenza viruses.

The Challenge: The health of the abundant waterfowl species of Chesapeake Bay has become a major concern due to the spread of Avian Influenza (AI) across North America and the role of waterfowl as a vector of AI. For decades, the health of the Bay’s waterfowl has been affected by the degradation of water quality and food supply due to industrial contaminants,agricultural run-off, pollution from...
