Surveillance Program

Data are being collected on a weekly basis and are reported for the following five categories: wild birds, sentinel chicken flocks, human cases, veterinary cases, and mosquito surveillance.  See the Epidemic/Epizootic West Nile Virus in the United States: Revised Guidelines for Surveillance, Prevention, and Control, 2003 Adobe Acrobat Reader(254 KB, 77 pages) for a full description

Surveillance and Control Guidelines

Revised guidelines are available to assist public health professionals with West Nile virus surveillance and control efforts. See Epidemic/Epizootic West Nile Virus in the United States: Revised Guidelines for Surveillance, Prevention, and Control, 2003 Adobe Acrobat Reader(254 KB, 77 pages)

Subjects covered include surveillance, laboratory diagnosis, prevention and control methods (including such topics as source reduction and biological control), health department infrastructure recommendations, data sharing and reporting, and research priorities.

Case Definition

See the case definition (2004) for Neuroinvasive and Non-Neuroinvasive Domestic Arboviral Diseases (includes diseases caused by California serogroup viruses; eastern and western equine encephalitis viruses; and Powassan, St. Louis encephalitis, and West Nile viruses). From the CDC Epidemiology Program Office.
