**** total number of human cases of WNV illness reported to ArboNET by
state and local health departments.
"Neuroinvasive disease" refers to severe disease cases, particularly West
Nile meningitis and West Nile encephalitis.
"West Nile fever" refers to typically less severe cases that show no
evidence of neuroinvasion. West Nile fever is not currently on the list of
nationally notifiable diseases, and, therefore, it is optional whether or
not state health departments report these cases to CDC. [Further
explanations of neuroinvasive West Nile virus disease and West Nile fever
can be found on the CDC website at the URL provided above.]
"Other" includes persons with clinical manifestations other than WN fever,
WN encephalitis, or WN meningitis, such as acute flaccid paralysis.
"Unspecified" cases are those for which sufficient clinical information was
not provided.
"Total human cases reported to CDC:" these numbers reflect both mild and
severe human disease cases occurring since 1 Jan 2007, reported to ArboNET
by state and local health departments.
ArboNET is the national electronic surveillance system established by CDC to
assist states in tracking West Nile virus and other mosquito-borne viruses.
Information regarding 2007 virus/disease activity is posted when such cases
are reported to CDC.

2007 West Nile virus activity in the United States (through 18 Sep 2007)
------------------------------------------------------------------------
Data are being collected from state and local health departments on a
weekly basis and are reported to the CDC ArboNET for the following 5
categories: wild birds, sentinel chicken flocks, human cases, veterinary
cases, and mosquito surveillance. Maps detailing county-level wild birds,
sentinel chicken flocks, human cases, veterinary cases, and mosquito
surveillance data are published each week on the collaborative USGS (US
Geological Survey)/CDC West Nile virus website.
As of 18 Sep 2007, human, avian, animal, or mosquito West Nile virus (WNV)
infections have been reported to CDC ArboNET from the following states:

South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia,
Washington, West Virginia, Wisconsin, and Wyoming; Commonwealth of Puerto Rico.
WNV antibody-positive sentinel animals (birds and/or horses) have been
found in Arizona, Arkansas, California, Delaware, Florida, Iowa, North
Dakota, Oregon, Puerto Rico, and Utah. [Note: not all states have WNV
sentinel programs. - Mods.JW/TY]
WNV equine infections have been reported from Arizona, California,
Colorado, Idaho, Illinois, Iowa, Kansas, Kentucky, Louisiana, Minnesota,
Mississippi, Missouri, Montana, Nebraska, Nevada, New Mexico, North Dakota,
Oklahoma, Oregon, South Dakota, Tennessee, Texas, Utah, Virginia,

California, Colorado, Delaware, Georgia, Idaho, Illinois, Indiana,
Kentucky, Massachusetts, Michigan, Mississippi, Nebraska, Nevada, New
Hampshire, New Jersey, New Mexico, New York, North Dakota, Ohio, Oregon,
Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Utah,

WNV has been detected in mosquito pools collected in Arizona, Arkansas,
California, Colorado, Connecticut, Georgia, Idaho, Illinois, Indiana, Iowa,
Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Minnesota,
Mississippi, Missouri, Nebraska, Nevada, New Jersey, New Mexico, New York,
