Chronic Wasting Disease

Chronic wasting disease (CWD) has been detected in 31 US states and four Canadian provinces in free-ranging cervids and/or commercial captive cervid facilities. CWD has been detected in free-ranging cervids in 31 states and three provinces and in captive cervid facilities in 18 states and three provinces.

Multiple studies have demonstrated that various alleles of the cervid prion protein (PRNP) gene affect chronic wasting disease (CWD) progression.

Managing chronic wasting disease (CWD) involves more than understanding the ecology of the disease. It includes complex relationships among social, economic, and political factors that affect intervention opportunities, consequences for stakeholders, and ultimately disease outcomes. The USGS National Wildlife Health Center, Montana Cooperative Wildlife Research Unit, Ventana Systems, Inc., and the...

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.

Chronic wasting disease (CWD), a fatal neurologic disease of cervids, presents a monumental management challenge, in part because the etiological agent, an infectious prion, is extremely difficult to inactivate and can be transmitted directly or indirectly to hosts. Due to these attributes of prions, proper disposal of CWD-infected carcasses is an important consideration for management agencies to...

Chronic wasting disease (CWD) is an emerging infectious disease that is fatal to free-ranging and captive animals in Cervidae, the deer family. The development of the real-time quaking-induced conversion (RT-QuIC) assay has the potential to transform laboratory research of prions and provide new opportunities for improved surveillance and management.

Chronic wasting disease (CWD) is an emerging infectious disease that is fatal to free-ranging and captive animals in Cervidae, the deer family. CWD is one member of a family of diseases called transmissible spongiform encephalopathies (TSEs), and is thought to be caused by prions. CWD is the only TSE known to affect free-ranging wildlife.
