On March 7, 2014 two barrel horses located North of Stillwater were tested positive for EHV1. One horse was euthanized.
On March 17, 2014 one barrel horse located North of Stillwater in Wisconsin showed signs consistent with an EHV1 infection, and is currently down and unable to get up. Tests are pending.
On March 18, 2014 a Barrel horse was taken to the University of Minnesota for neurologic symptoms ( EHV1 like symptoms) and was euthanized. Tests are pending
On March 18, 2014 a Barrel horse was examined in the west metro area for neurologic symptoms (EHV1 like symptoms) and is being treated. Tests are pending.
At this time we are recommending that barrel horses do not travel to shows until these tests are completed and the extent of this outbreak can be determined. EHV 1- Information from Millhouse Veterinary Service
WHAT IS EHV-1 ?
There has been information coming your way from a few different sources, regarding this outbreak. Our intent here is not to sound the alarms but to give you the information you need to make the best decisions for your horse/s. We will attempt to make this brief with the important points only.
Equine Herpesvirus EHV-1 neurologic strain is what the outbreak concern is and there are currently no equine vaccines labeled to protect against this strain. Protection of the respiratory form of this can be prevented by the "Rhino" vaccine your horse normally would receive. This vaccine does not protect against the neurologic form although may theoretically reduce nasal shedding and viremia. Rhino vaccines have a short effectiveness and may need to be boostered.
Transmission: Highly contagious!
Horse to horse contact
Aerosol transmission (airborne)
Contaminated hands, equipment, tack, and feed...
The virus can live for several weeks in the environment once it has been shed by a horse. (up to 35 days)
Incubation: As short as 24 hours
Typically 4-6 days but can be longer
Shedding: Horses can shed virus for 1-3 weeks past
resolution of clinical signs.
Signs: Fever precedes other clinical signs
Respiratory disease- fever, cough, nasal discharge
Abortion in pregnant mares
Neurologic disease- incoordination, usually hind end, urine retention/dribbling, recumbency.
**Neurologic signs may be preceded by fever and
respiratory signs.
Prevention: Limit exposure, quarantine your barn from
unnecessary horse traffic and keep your horse/s at home
Monitor horse/s for spike in temperature.
Isolate sick or exposed horses.
Vaccinate on risk-base.
Immune Boosters on a risk-base.
Prognosis: Mortality rates are high for the neurologic form of EHV-1
Again, this information is not meant to cause alarm but to inform you of the potential outbreak in our area. As we learn more information, we will pass it on to you. Be thoughtful of handling horses returning from events where there may have been exposure.
