The Maryland State Veterinarian Dr. Jennifer Trout told The Equiery that it received confirmation today that a trail riding horse in Cecil County with neurological symptoms tested positive today for EHV-1.
Intrastate CVI rules will remain in effect through the end of January. According to Dr. Trout:
“This afternoon, the Animal Health Program received confirmation of a positive EHV/EHM case within the state. As a result, equine travel requirements, both within Maryland and across state lines, will remain in effect until the State Veterinarian determines that the risk level no longer warrants Certificates of Veterinary Inspection (CVIs). At a minimum, these requirements will remain in place through January 2026. These measures were implemented out of an abundance of caution to protect Maryland’s equine industry. Past experience has shown that the absence of such requirements can contribute to increased disease spread and severity. The program is also evaluating the continued need for intrastate equine CVIs following the EHV/EHM outbreak, given ongoing challenges with compliance to recommended disease control precautions during outbreak situations. Current equine travel requirements are posted on the MDA website.”
