Colorado Declares Equine Virus Contained

EHV-1 contained in Colorado with nine confirmed cases.

The Colorado Department of Agriculture's State Veterinarian's office has released a number of quarantine and hold orders associated with the recent spread of Equine Herpesvirus in the state.

The disease is now considered contained within Colorado and no new case has been confirmed since May 20.

"I'm proud of the coordinated effort by the horse industry, veterinarians, event coordinators, and our office," says Keith Roehr, state vet. "Without this proactive collaboration of all involved, this disease could have had an even greater negative impact on Colorado's horse industry."

As the end of June, Colorado totaled nine confirmed finds of EHV-1. Two horses, which tested positive, were euthanized after showing severe neurological signs associated with the disease. There are currently no new suspect cases.

Two facilities remain under quarantine or a hold order, but those facilities are on track to be released soon.

"This is great news for Colorado's horse industry and it seems this disease hit its peak in May, but I want to caution horse owners that this outbreak serves as a good reminder that proper disease prevention efforts are important any time you travel with livestock," says Roehr.

"This outbreak also demonstrates how our animal health and disease control processes work together for successful outcomes."

Horse owners are encouraged to review these travel tips from the CDA:

n  Contact the state veterinarian's office of the destination state you travel to for information on travel requirements which may have changed recently.

n  Call organizers of horse events to see if they have new health requirements.

n  Practice biosecurity measures. Tips may be found at

n  Isolate any new animals and those returning to home premises for three weeks when possible.

n  Use separate water, feed supplements and equipment.

Colorado has established new travel requirements for horses entering the state which call for a health certificate issued within 30 days of arrival, and a negative Coggins test within 12 months. A permit is required to bring a horse into the state.

Horse owners bringing animals into the state must contact their veterinarian first, who will help obtain a permit.
