Chronic wasting disease (CWD), sometimes called zombie deer disease, is a transmissible spongiform encephalopathy (TSE) affecting deer.TSEs are a family of diseases thought to be caused by misfolded proteins called prions and include similar diseases such as BSE (mad cow disease) in cattle, Creutzfeldt–Jakob disease (CJD) in humans, and scrapie in sheep.

The U.S. Geological Survey updated its tracking of chronic wasting disease on Friday to include 33 states (adding Indiana), as well as four Canadian provinces and four other countries (Finland ...
Chronic wasting disease (CWD) is a disease rapidly spreading throughout populations of the Cervus family. [75] It first appeared in captive deer in Colorado in 1967 but has made a large impact on wild mule deer populations since then, spreading throughout all of North America. [76]
Georeferenced map images are available from the USGS as digital raster graphics (DRGs) in addition to digital data sets based on USGS maps, notably digital line graphs (DLGs) and digital elevation models (DEMs). In 2015, the USGS unveiled the topoView website, a new way to view their entire digitized collection of over 178,000 maps from 1884 to ...

The detection makes Washington the latest domino to fall in the disease's slow progression throughout North America. ... Aug. 1—Washington has its first case of chronic wasting disease. The ...
Information included in the Atlas includes accurate, seamless maps, documentation, and geospatial data that crosses political borders. This data is displayed as series of interactive map layers in an easy to use map viewer format. Most layers in the North American Environmental Atlas are at a scale of 1:1:10,000,000 or finer.

Chronic wasting disease, transmitted by a misfolded protein known as a prion, affects the brain tissue in elk, and has been detected throughout their range in North America. First documented in the late 1960s in mule deer, the disease has affected elk on game farms and in the wild in a number of regions.
