This report presents provisional summary surveillance data about West
Nile virus (WNV) activity that were reported to CDC during January 1–November
30, 2002, through the ArboNET surveillance network. In 2002, the reported
numbers of human and animal infections increased, and the geographic range
of WNV activity expanded substantially. These data underscore the need for
intensive surveillance to detect and quantify WNV activity in areas where
humans are at risk, public education to teach persons how to prevent mosquito
bites, and sustained and integrated mosquito-control activities.
ArboNET is a web-based surveillance data network comprising 54 state
and local public health departments and CDC. Specimens from ill humans and
animals, dead birds, captive sentinel animals (mostly chickens), wild-caught
birds, and mosquitoes were collected by state and local public health departments
and other cooperating state and federal agencies and tested for WNV or WNV-specific
antibody. Test results, the county and date of specimen collection or illness
onset, and other data were entered into state and local public health department
databases. Animal data were forwarded regularly to ArboNET through a secure
data network; human cases were reported to CDC by telephone or facsimile only.
