Wildlife biologists from the U.S. Geological Survey, in partnership with other federal, state and local agencies are studying the newly discovered West Nile-like virus which has been blamed for the deaths of three people in New York City and the deaths of many birds in the city and surrounding areas.
On Wednesday, USGS wildlife biologists issued a Wildlife Health Alert to federal and state wildlife conservation agencies, parks, refuges and other wildlife agencies east of the Mississippi River to be on the lookout for dead crows and other birds which may indicate that this mosquito-borne virus has appeared.
USGS biologists, teaming with scientists and managers from the U.S. Centers for Disease Control and Prevention (CDC) and health and environmental departments in the New York City, New York State, Connecticut and New Jersey, are working to determine the extent of the problem in the Northeast.
Beginning next week, USGS field teams will be in New York and other areas capturing live birds, taking blood samples and releasing them. The samples will be sent to the National Wildlife Health Center for testing in an effort to detect West Nile-like virus and to the CDC laboratory in Fort Collins, Colo., to test for antibodies. USGS biologists at the USGS National Wildlife Health Center (NWHC) in Madison, Wis., in collaboration with CDC will be analyzing samples from dead crows to determine if the virus is present. Crows appear to be very sensitive to infection with this virus and thus may be a good indicator of its presence.
"We're trying to map the distribution of this disease in birds both spatially
and temporally. And we want to try to determine if it is expanding," said Dr.
Robert McLean, a USGS wildlife biologist and NWHC Director who is leading the
study. "We're watching areas particularly south of New York for crows which have
died from diseases and then try to determine if this virus was responsible. We
would like also to determine what ot
