Testing is critical to controlling spread of the virus, and Colorado State University’s Veterinary Diagnostic Laboratory, or VDL, is playing a key role, regularly testing samples from birds, cattle and other species. Understanding how disease is affecting wild and domestic animals is a mission of the lab in Fort Collins, and that information is essential for animal and public health officials, food-animal producers and others to respond effectively to halt the spread of disease and curb potential impacts to human health.
