On Tuesday, July 10, 2018, the Maryland Department of Agriculture confirmed one case of equine infectious anemia in Montgomery County. The positive horse was discovered during a routine wellness examination by a private veterinarian. The infected horse did not display any clinical signs, but was determined to be in the carrier state of the disease. The positive diagnosis was confirmed by the National Veterinary Services Laboratory on Monday, July 9, 2018. The infected horse will be euthanized.
The State Veterinarian’s Office has placed the facility under quarantine and will retest after 60 days to make sure no more horses test positive.
