What is Avian Influenza (AI)?
USGS is the lead Federal agency for free-ranging wildlife disease research and surveillance. Our capabilities enhance the understanding of wildlife disease ecology and epidemiology as well as inform the development of decision-support and control tools. USGS wildlife disease experts provide technical assistance as needed to manage wildlife disease and conduct cause-of-death investigations.

Avian Malaria Genomic Research Project
Many factors including habitat destruction, invasive plants, non-native predators and competitors, and introduced diseases have decimated the diverse, endemic native forest bird community of Hawai‘i. In particular, avian malaria ( Plasmodium relictum), which is transmitted by the introduced southern house mosquito ( Culex quinquefasciatus), has caused dramatic declines and extinctions in many...
SARS-CoV-2 in Wildlife
As SARS-CoV-2, the virus that causes COVID-19 in humans, continues to spread globally, questions have emerged about the potential for humans to transmit the virus to North American wildlife, its potential effects on native wildlife populations, and the resultant possibility and consequences of establishing a persistent wildlife reservoir. Recent studies have detected SARS-CoV-2 in escaped or wild...
Field trials for testing of white-nose syndrome vaccine candidates
White-nose syndrome (WNS), caused by the fungus Pseudogymnoascus destructans (Pd), continues to decimate bat populations in North America, and efforts to develop treatment options have intensified. One potential method for controlling WNS is vaccination of bats with specific antigens to elicit a protective immune response.
Decision science support for Chronic Wasting Disease
Eastern Ecological Science Center adds the decision analytical skill set to the existing body of USGS expertise on Chronic Wasting Disease (CWD), in support of our sister DOI agencies.
Chronic Wasting Disease (CWD) Detection in Cervids Using MicroRNA Biomarkers from Blood
WARC scientists are testing and developing methods for the isolation of cervid exosomes from blood samples, followed by microRNA extraction and next generation sequencing.
Evaluating Transmission of Chronic Wasting Disease in the Environment
Chronic wasting disease (CWD) is a fatal disease of deer, elk, and moose and has been spreading in North America for the past two decades. The disease is spread by infected body fluids. Animals can become infected by coming into direct contact with a CWD-infected animal, or an infected animal can leave behind fluids (e.g., saliva, urine) that an uninfected animal will come into contact later...
Research in response to Florida’s emerging coral disease
Coral reefs are both ecologically and economically important, serving as nurseries for fisheries, protecting the coastline from storm surges, and generating income from tourism. Since 2014, a wide variety of corals have been dying from unexplained causes throughout South Florida with mortalities ranging from North Miami to the Florida Keys.
Development of SARS-CoV-2 vaccine to support black-footed ferret conservation
The SARS-CoV-2 virus is known to infect and cause severe disease, such as respiratory distress and death, in mustelids, including farm-raised mink ( Mustela lutreola and Neovison vison) and domestic ferrets ( M. putorius). This raised concern that the virus may also pose a threat to endangered black-footed ferrets ( Mustela nigripes) managed in captivity for breeding and recovery purposes.
Enhanced Capacity for Chronic Wasting Disease Research and Certified Diagnostics at the USGS National Wildlife Health Center
Chronic wasting disease (CWD) is a fatal disease that impacts populations of deer, elk, moose, and other cervid species caused by an infectious protein called a prion.
Asian Flyways Collaborative for Waterbirds (AFCoW)
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...
Quarterly Mortality Reports
The National Wildlife Health Center produces quarterly wildlife mortality reports, containing information about wildlife mortality events throughout the United States and on occasion across North America.
Detecting Sublethal Effects of Harmful Algal Blooms in Mammalian and Avian Cells
USGS Researchers are collaborating to study avian and mammalian cells to detect sublethal toxin effects following exposure to harmful algal blooms.
