State vet advises precautions with equine herpes virus-1 (rhino)

May 18th, 2011

Editiorial Note: ODS has not made any official decisions about event cancellation.  Please continue to be patient and to watch this page for details.

State vet advises precautions with equine herpes virus-1 (rhino) As of noon on May 18, 2011, Oregon has one confirmed case of the neugological herpes virus (Equine Herpesvirus Myeloencephalopathy) or EHM, out of a number of horses that attended or participated in the cutting event held in Ogden, Utah from April 30 through May 8, 2011. This confirmed case is directly linked to the cutting event held in Utah. A number of other cases have been confirmed in surrounding states including, Washington, Idaho, California and Colorado.  EHM is a highly contagious nerological virus that can cause severe neurological symptoms in horses.
There are no restrictions on the movement of non-exposed horses within Oregon at this time.

Effective immediately EHM is a reportable disease to the state veterinarian. For clinical or suspect cases please call and report to Dr. Don Hansen, State Veterinarian at (503) 986-4680, immediately.

State Veterinarian Don Hansen urges horse owners to take precautions. Veterinarians should work closely with their equine clients to develop plans that address the clients’ ability to prevent EHM in their horses. If a horse is suspected of having EHM, the horse should be isolated. Do not use the same equipment when handling other horses.

Take precautions with Equine Herpes Virus-1 (Rhino) – Current “Outbreak” Information

May 16th, 2011

Take precautions with Equine Herpes Virus-1 (Rhino)

A recent outbreak of Equine Herpes (Myeloencephalopathy) Virue-1 (EHV-1) has been reported among horses that attended the National Cutting Horse Association’s Western National Championship in Ogden, Utah from April 30 through May 8, 2011.  Horses who participated in this event MAY have been exposed to this EHV-1 virus.  At this time we have not confirmed any cases in Oregon but are contacting all horse owners who attended the event with their horse(s).

Even though EHV-1 is not a regulatory disease, and is not reportable, we are asking all veterinarians to call our office with any CONFIRMED cases (503-986-4680).

Veterinarians should work closely with their equine clients to develop plans that address the clients’ ability to prevent EHV-1 in their hoses.   And, if a horse is suspected of having the viral disease, it should be isolated.  Equipment should not be shared.

Enforcement of strict biosecurity measures and hygiene practices are likely to be more effective than widespread vaccination in reducing the risk of acquiring infection.  Nevertheless, recent research demonstrates that viral shedding is much reduced in horses with high circulating titers of virus-neutralizing (VN) antibody, as well as in horses that have been vaccinated recently with the Rhinomune MLV vaccine.

Following are links for EHV-1 from the California Department of Food and Agriculture and UC Davis that will help readers become informed about this disease.

Some of the points made on these Web sites are summarized below.

Potential Clinical Signs of EHV-1

  1. Respiratory signs (Signs may be minimal and of short duration.):

l  Increased rectal temperature may be the only clinical sign

l  Horses can have two fever spikes

l  The initial rise in rectal temperature is usually mild – 101.5 to 102.5°F

l  After the initial temperature rise, which may be missed, the horse can either be clinical normal, develop respirator signs of nasal discharge, increased temperature (> 102.5), minimal coughing, can abort if pregnant, or, in a small number of cases develop neurological signs.

  1. Neurological signs:

l  Horses become ataxic (in coordination), inability to empty bladder, and weakness of the tail.  Some horses will become completely paralyzed; the prognosis for these horses is poor.  In a small number of cases, horses can show abnormal mentation and develop cranial nerve signs.  Most horses become mildly to moderately neurologic and stabilize rapidly.  The neurologic signs can persist but most horses are normal by 3 to 6 months after onset of clinical signs.

  1. Abortion:
  • Pregnant horses can experience spontaneous abortion between 7 days and several months after exposure.  The mare will exhibit limited initial signs.

l  Many times when horses are incubating the virus, fever in excess of 102°F may be the only observable sign of infection.  However, fever may not be present in all neurogenic clinical cases.

l  Stress and lack of previous exposure to the virus may make the horse more susceptible to becoming clinically ill.

l  Currently, there is no equine vaccine that has a label claim for protection against the neurological strain of the virus.

l  It is virtually impossible at this time to know if horses in our native population have ever been naturally exposed to recently diagnosed strains of EHV-1 and whether these individuals develop any subsequent immunity to the virus.

l  EHV-1 infected horses, whether clinically ill or not, may periodically shed both active and nonreplicating (dead) virus in their nasal secretions.  If the virus being shed is active, these horses have the potential to spread the virus to other horses.  Horse-to-horse contact, contaminated hands, equipment, tack, feed, and aerosol transmission all play a role in its spread.

l  It is felt that horses with severe clinical signs of neurological EHV-1 illness often have very large viral loads in both their blood and nasal secretions.  These high viral loads are thought to be a significant aspect in the transmission of the disease to exposed horses.  Therefore rapid separation and isolation of identified suspect cases and biosecurity are key elements for disease control.

l  As with all contagious diseases, if horses are commingled with strange horses, an unknown degree of inherent risk exists for exposure to EHV-1.  Many factors may enhance or reduce the amount of risk.  If the choice is made to commingle with a population that has the potential to harbor EHV-1 infected individuals, there is no foolproof way to completely eliminate the risk of exposure.

l  If horses are exposed to new horses, especially in stressful competitive environments or following long distance travel, it is helpful to establish a disease-monitoring plan under the advice of a veterinary practitioner.  Temperature monitoring (2x / day) is a tool to be used for a differential diagnosis that could include EHV-1.

Umpqua Valley Chapter News – May 2011

May 15th, 2011


A chilly April kicked off the show season with several results in. The HS Dressage benefit show at Wishing Well Farms was well attended, despite ominous weather. High percentage Intro rider went to Samantha Smith with a 78.13%, High percentage Training level was Marilyn Ulicny with a 73.57%, High Percentage First Level went to Leanne Macfarlane with a 68.39%. High percentage Jr rider was Mckenna Foley and High percentage young rider was Katie Jensen. On the eventing side, Whitney Weston has had a busy April with an 8th and 12th at Twin Rivers HT, then a 1rst and 2nd at Aspen Farms Derby, moving up to intermediate with “Ted” at the
NEC Mothers Day Classic. Rain shortened the cross country day, but all 3 horses went well, with Ted jumping fast and clear at his first intermediate event! Whitney cancelled her trip to Woodside, CA May 22 due to concerns over the EHV-1 virus. Cassi Soule made her 4th level debut with Debbie Beckland’s gelding Goldsun at the Starr Vaughn dressage show in Elk Grove, CA. They scored a respectable 56 under some difficult riding conditions at the show.  The Salute to Dressage show in Talent, Or was rescheduled to 6/18 due to the Rhino outbreak. Correction from last months newsletter. I mistakenly reported that Leanne McFarland received first
place at second level riding 2nd:1 and 1st:3 on Thor with scores of 63%. In fact, her first level test score was a 68.39%, and her second level test score was 63%. My apologies.

Stephen Clarke named head Olympic dressage judge

May 12th, 2011


Top-level British dressage judge Stephen Clarke will be the President of the Dressage Ground Jury for the London 2012 Olympic Games.

Stephen Clarke

The appointment was made at the recent FEI Bureau Meeting in Switzerland.

“I feel deeply honoured to have been awarded this appointment by the FEI. Of course it comes with a huge amount of responsibility which is not to be taken lightly,” Clarke said.

“Having been a member of the judging panel in Athens, the original home of the Olympic Games, to be invited again to judge in London is indeed a dream come true.”

Clarke, who is Director of Judges for British Dressage, rode internationally through the 70s and 80s, collecting five National titles along the way. After hanging up his competitive boots, he turned his focus to training, organising and judging. He now travels the world judging at major competitions and Championships and delivering training clinics both on riding skill and judging.

As an FEI ‘O’ or 5* Judge, Clarke has officiated at five World Cup Finals, three European Championships, three World Equestrian Games and London will be his second Olympic Games. He is a Fellow of the British Horse Society and was presented with a Queens Award for Equestrianism in 2010.

“I was so thrilled, as we all were, when it was announced a few years back that London had won the bid to host the Olympic Games in 2012. To now think of being part of this event is beyond exciting!” Clarke said.

“The rest of the judging panel have not been announced yet but, without doubt, they will be selected from the best in the world. I look forward to working with them at this illustrious event where we will do our utmost to ensure a fair result for every rider who will be taking part in the Games.”

British Dressage Chief Executive Amanda Bond said appointment was not only a great honour for Clarke, but for the country, and it cemented Britain’s standing in the international dressage community. “Stephen’s contribution to the sport has been monumental – from his influence in modernising the way our judges work to his continual encouragement to improve standards and fairness – he’s really helped the sport progress. This is just reward for him personally and we are looking forward to 2 August next year when the first Dressage horse trots down the centre line in Greenwich.”
