From July 1 – October 31 of each year, the Laboratories Administration will accept serum, brain, and/or CSF samples from horses exhibiting clinical signs consistent with arboviral disease for testing. A veterinarian wishing to request arboviral testing of equine specimens should first contact the Center for Zoonotic and Vector-borne Diseases (CZVBD) at
410-767-5649 to coordinate submission of specimens. An Equine Arboviral Testing Form must accompany each submission.
