So far, the seven positive New York CWD deer were found in Oneida County. The first positive findings were from captive deer kept on farms, while the latest positives were discovered as a result of NY State testing of several hundred deer from Oneida county and surrounding areas. It is unclear whether CWD first affected deer on the farms, who then transmitted the disease to the wild deer population, or if the disease spread from the wild to the farm. Although CWD has not been found in other parts of NY, it is highly transmissible between deer. Other states have found that once the disease becomes endemic, it is close to impossible to contain and control.
