West Nile Virus Found In
Arizona For First Time

From Patricia Doyle, PhD

I had been hoping that States like Arizona and Nevada with hot, dry climates, would have been spared from West Nile Like Virus. It appears that NY99 West Nile LIKE virus is determined to spread.

Mosquito sample tests positive for West Nile virus in SE Arizona ----------------------------------------------------------------
A mosquito sample collected by Cochise County health officials in the San Simon area has tested positive for the West Nile virus, marking the emergence of the virus in the state. San Simon is located in south eastern Arizona near the New Mexico border.
Although testing of specimens from birds, horses, sentinel chicken flocks, and mosquito pools began in Arizona in May 2003, the mosquito sample in Cochise County is the only one that has tested positive for West Nile virus, so far. This year, the Arizona State Health Laboratory has tested over 800 mosquito [pools?] and more than 900 chicken blood samples. In addition, the University of Arizona Veterinary Diagnostic Laboratory has tested over 300 dead birds and more than 20 horses.
West Nile virus is not the only encephalitis-causing virus circulating in Arizona this summer. St Louis encephalitis (SLE)-positive mosquito samples and/or chicken blood samples were collected in Maricopa and Yuma counties, and western equine encephalitis (WEE) positive samples were collected in Apache, Maricopa, and Pinal counties.
To bolster the state's West Nile virus surveillance efforts, the Arizona Department of Health Services today issued an emergency order making West Nile virus a reportable disease. Under the order, a physician or an administrator of a health care facility is required to submit a communicable disease report of a case or a suspect case of West Nile within 24 hours of diagnosis to the local health agency. In addition, clinical laboratories are required to report to the Department.
