Summary One of the potential effects of global climate change is the spread of disease to new areas, as the vectors of those diseases (e.g., mosquitoes, birds) expand into new locations in response to shifting climate conditions. Although the direct cause of West Nile Virus (WNV) in the United States is not known, the National Atlas of the US Geological Survey (reviewed in ... the June 26, 1998 Scout Report) has recently launched this new resource on WNV distribution. First documented in the US during the summer of 1999 and previously limited to Africa, Eastern Europe, West Asia, and the Middle East, the West Nile Virus is of danger to humans as it interferes with "normal central nervous system functioning" and can cause encephalitis.
The online, interactive mapping system allows you to design and query your own maps using more than 100 different map layers. Other portions of the site describe WNV Surveillance Activity for the year 2000 and offers a series of maps highlighting the US distribution of WNV cases found in humans, wild birds, chickens, mosquitoes, and veterinary clinics. A series of links point to further information on the virus.
The multimedia maps and charts are designed to illustrate documented occurrences of WNV over time. Let your cursor roam over the map and images and enjoy the exploration. In addition to interactive maps, the National Atlas of the United States includes page-size (8.5 by 11 inch) maps designed for printing and reproduction. These maps are offered in the following file formats:
- Graphic Interchange Format (GIF) format. Maps in this format can be viewed in your browser window. - Portable Document Format (PDF). You'll need Acrobat Reader software to view and print PDF files. Get Acrobat Reader. - Encapsulated PostScript format (EPS), a format used by publishing professionals. The National Atlas EPS files were generated as Adobe Illustrator 8.0 files.

Description:
Each week from May 13, 2000 through December 8, 2000, the National Atlas
included a new series of maps resulting from West Nile Virus (WNV) surveillance
activities Although there are no new maps being created, these four types of
map services are still available:
* online interactive maps,
* dynamic multimedia maps,
* map layer data available for download, and
* high quality maps for printing and reproduction.
The map subjects were:
* Human Cases
* Mosquito Surveillance
* Sentinel Flock Surveillance
* Veterinary Cases
* Wild Bird Cases

Description:
West Nile (WN) virus has emerged in recent years in temperate regions of Europe
and North America, presenting a threat to public, equine, and animal health.
The most serious manifestation of WN virus infection is fatal encephalitis
(inflammation of the brain) in humans and horses, as well as mortality in
certain domestic and wild birds.
