West Nile Virus
Kennewick, WA
Information Only
July 21, 2015-- The Washington State Department of Agriculture (WSDA) is reporting that a five-year-old Quarter horse gelding in Kennewick is the first equine in the state to contract West Nile virus this year. The horse, which was not vaccinated for the disease, has not left the owner’s property recently. The horse’s status is improving. The Washington Animal Disease Diagnostic Laboratory in Pullman, operated by Washington State University, reported the positive test results to WSDA’s State Veterinarian’s Office Friday. Washington had five confirmed cases of horses with West Nile virus last year, including horses in Benton, Franklin, Grant, Okanogan and Yakima counties. West Nile virus is spread by mosquitoes that have fed on infected birds. The disease sickens people, horses, birds and other animals, but it does not spread directly from horses to people or other animals. The disease is fatal to horses in about a third of the cases in which clinical signs are apparent, although most horses do not become ill and show no symptoms. Horses that do become ill can appear to be displaying loss of coordination, loss of appetite, confusion, fever, stiffness, and muscle weakness, particularly in their hindquarters. State Veterinarian Dr. Joe Baker recommends spring as the best time to vaccinate horses against West Nile virus or obtain an annual booster shot. However, horses may still benefit from first-time vaccinations or an annual booster shot. Horse owners not up to date on shots may benefit from a visit with their veterinarian to determine a vaccination protocol that best fits their situation.

Vesicular Stomatitis
Montrose County, Delta County, CO
Confirmed case(s) quarantined
June 2, 2015-- Horses on two Montrose and one Delta County premises tested positive for the disease and have been placed under quarantine. Colorado has become the fourth state in the country to have confirmed cases of vesicular stomatitis (VS) in 2015. Previous positive cases of vesicular stomatitis this year have been diagnosed in Arizona, New Mexico and Texas. On July 2nd, the National Veterinary Services Laboratory reported positive tests on samples submitted from horses in Montrose and Delta Counties. The initial Colorado disease investigations were accomplished by field veterinarians from the State Veterinarian’s Office at the Colorado Department of Agriculture. “The primary spread of VS is thought to occur through insect vectors; the horses involved in these cases have no history of travel,” said State Veterinarian, Dr. Keith Roehr. “Vesicular stomatitis can be painful for animals and costly to their owners. The virus typically causes oral blisters and sores that can be painful causing difficulty in eating and drinking.” A 2014 outbreak of VS created 556 livestock investigations in Colorado resulting in 370 quarantines with the final quarantines released in January 2015. Livestock owners who suspect an animal may have VS or any other vesicular disease should immediately contact their local veterinarian. Livestock with clinical signs of VS are isolated until they are determined to be of no further threat for disease spread. There are no USDA approved vaccines for VS. While rare, human cases of VS can occur, usually among those who handle infected animals. VS in humans can cause flu-like symptoms and only rarely includes lesions or blisters.

This is the first case of VS in Reeves County this year. On May 19, 2015, the Texas Animal Health Commission (TAHC) announced the State’s first case of VS involving three horses in Pecos County. The newly identified infected premises is currently under quarantine by the TAHC. Affected horses will be monitored by regulatory personnel until all lesions have healed and a decision is made to release the quarantine (a minimum of 14 days). There is no known exposure to other horses around the state, or at any equine events. It is believed that the virus overwinters in the sand and black fly population in northern Mexico and then moves northward in warmer weather.

Equine Herpes viruses
San Luis Obispo County, CA
Confirmed case(s) quarantined
May 21, 2015 : A 7 year old barrel racing Quarter Horse gelding, originating from San Luis Obispo County, displaying mild hind limb ataxia was confirmed positive for the non-neuropathogenic strain of Equine Herpesvirus-1. This strain of virus is responsible for the more common rhinopneumonitis cases. A small percentage of the non-neuropathogenic infected horses can display neurologic signs compatible with equine herpes myeloencephalopathy which is a reportable disease in California. The quarantined gelding is under veterinary care in Santa Barbara County and is recovering. An investigation has been initiated and owners with potentially exposed horses will be contacted. Owners of exposed horses are asked to monitor their horses for clinical signs and take temperatures twice daily. CDFA will continue to monitor the situation.

Vesicular Stomatitis
Pecos County, TX
Confirmed case(s) quarantined
AUSTIN- Vesicular stomatitis (VS) has been detected in three horses at a Pecos County premises located approximately 30 miles north of Fort Stockton, Texas. The animals were tested after the owner observed blistering and swelling on the animals' tongues and lips, and contacted their veterinary practitioner. Testing at the USDA National Veterinary Services lab in Ames, Iowa confirmed the New Jersey serotype of virus in the affected horses. Vesicular stomatitis primarily affects horses and cattle causing blisters or sores on the tongue, lips, muzzle, nose, hooves and/or teats. Because of the contagious nature of VS and its resemblance to other diseases such as foot and mouth disease (FMD), the Texas Animal Health Commission (TAHC) urges livestock owners and caretakers to report these symptoms to their veterinarian or the TAHC immediately. Although the lesions may be painful, most animals recover well with supportive care. VS can be transmitted by direct contact with infected animals, contaminated objects (fomites), or by insect vectors such as sand flies and black flies. The disease usually occurs in warm months of the year when insect vectors are active. VS may also affect people causing a mild flu-like illness with symptoms of fever, weakness, and muscle aches. The newly identified infected horses are currently under quarantine by the TAHC. Affected and exposed horses will be monitored by TAHC or USDA personnel until all lesions have healed and a decision is made to release the quarantine (a minimum of 14 days). "If you suspect your animal(s) have VS, you should notify your veterinarian immediately," said Dr. Dee Ellis, Texas' State Veterinarian and TAHC Executive Director. "Texas had its largest VS outbreak in history last year, and we must remain vigilant in protecting our livestock industry in 2015." The first case of VS this year was found in New Mexico on April 29, 2015. Since then, VS cases have also been confirmed in Arizona and Utah. Some states and other countries may restrict movement of, or impose additional requirements for susceptible species moving from states with active cases of VS. It is important for shippers or haulers of livestock to contact states of destination well in advance of scheduled movements to determine their entry requirements. For international export information, the USDA Veterinary Services office in Austin, Texas should be contacted.

Equine Herpes viruses
Forest County, PA
Ongoing(investigation)
Harrisburg, PA - The Pennsylvania Department of Agriculture today announced a quarantine of an equine barn in Tionesta, Forest County, after a horse at the barn tested positive for Equine Herpesvirus Type 1 (EHV-1) on Wednesday, May 13. A horse from the Forest County barn was used in the Tionesta Wounded Warrior Horseback Scavenger Hunt, where 94 horses took part, including horses from Ohio and West Virginia. An equine barn in Shippenville, Clarion County, housing an exposed horse that showed clinical signs of EHV-1, was put under precautionary quarantine Thursday, May 14, until the pending laboratory results are confirmed. Two additional horses from the Forest County equine barn have shown signs of illness after being exposed to the positive horse. The Pennsylvania Department of Agriculture is in the process of tracing the horses that participated in the scavenger hunt, and has notified animal health officials in Ohio and West Virginia. Clinical signs of the disease can range from respiratory to neurological impairment. In most situations, the disease is only mildly contagious. There is no threat to human health from Equine Herpesvirus. The barns and horses are quarantined for at least 21 days. The quarantine can be lifted after that three-week period. Strict sanitary and biosecurity standards are then enforced. Horse owners with concerns may contact the Department of Agriculture’s Bureau of Animal Health and Diagnostic Services at 717-772-2852.

Equine Herpes viruses
Marion and Polk counties, OR
Confirmed case(s) quarantined
May 14, 2015... There have been no additional cases of horses infected with Equine Herpes Virus (EHV-1) this week, according to State Veterinarian Dr. Brad LeaMaster of the Oregon Department of Agriculture. Over the previous two weeks, nine horses had either developed neurological signs of the infection or had developed fevers with no neurological signs after being exposed to EHV-1. All horses involved remain under active observation by owners and their veterinarians. Eight farms remain under quarantine, six in Marion County and two in Polk County. There have been no deaths associated with the EHV-1 outbreak so far. Two horses that were hospitalized at Oregon State University College of Veterinary Medicine’s Large Animal Hospital have responded to treatment and have been sent home. “The fact that there have been no new reports of the virus in Oregon is encouraging news and may indicate that the outbreak situation has stabilized,” says LeaMaster. All affected horses have been linked to an Oregon High School Equestrian Team (OHSET) meet at the Linn County Fairgrounds on April 16-19. “I am aware that many equine shows and other events have been cancelled or postponed this past week” says Brad LeaMaster. “It is a very tough decision to make, however, I commend those event organizers who made that call as well as the many horse owners who decided to just stay home. That was a responsible thing to do and I feel that those actions have been the key reason for no new infections being reported this past week.” ODA has received many inquiries from concerned horse owners on what to do if they have a potentially exposed horse. “Our recommendation is to isolate the animal and contact your veterinarian to discuss how best to monitor for signs of sickness as well as biosecurity details” says LeaMaster. Another frequently asked question is about the length of time for the quarantine to be in place. The eight premises under state quarantine will remain so for 28 days after the last infection.

Equine Infectious Anemia
Edgar County, IL
Confirmed case(s) quarantined
On Thursday May 7, the Bureau of Animal Health and Welfare received confirmation that a horse stabled in Edgar County has tested positive for Equine Infectious Anemia. The horse has been quarantined to the premises, and arrangements are being made for the disposition of the infected animal. In addition, all other equine on the premises will be tested. Bureau personnel will be conducting area surveillance testing of horses within a 1.5 mile radius of the quarantined premises. If additional infected animals are disclosed, the surveillance area will be expanded. History provided by the owner indicates that the infected horse has not been tested in recent years and has not been moved from the premises within the past couple of years. Horse owners are reminded that Equine Infectious Anemia can be transferred via contact with infected blood. Owners are encouraged to use appropriate insect control on animals and in and around buildings to decrease the possibility of exposure to biting insects. The sharing of needles between horses should always be avoided and equipment such as dental floats and bits should be properly disinfected before being used on other horses.

Equine Herpes viruses
Polk and Marion Counties, OR
Confirmed case(s) quarantined
May 4, 2015--Four Oregon horses have now tested positive for Equine Herpes Virus (EHV-1) with two of the horses showing neurological symptoms, according to the Oregon Department of Agriculture. It was confirmed last week that a Marion County horse had tested positive for EHV-1 and had developed neurological symptoms. The second horse that developed neurological symptoms resided at a stable in Polk County with about 40 other horses and was taken to the Large Animal Hospital at Oregon State University’s College of Veterinary Medicine over the weekend. The Polk County stable has been placed under quarantine and the remaining horses are being monitored by the stable manager and a veterinarian. In addition to the Polk County stable, two Marion County farms remain under quarantine due to exposure to EHV-1. The infected horses and other horses exposed at the quarantined facilities attended an Oregon High School Equestrian Team (OHSET) meet at the Linn County Fairgrounds on April 16-19. ODA is currently investigating the potential of any additional exposures at this time. In addition, ODA is working to notify owners of horses that have been potentially exposed and has notified Oregon equine veterinarians.

Equine Infectious Anemia
Henderson County, TN
Investigation(initiated)
NASHVILLE—The state veterinarian is advising horse owners of four confirmed cases of equine infectious anemia (EIA) in West Tennessee. Four horses stabled at three locations in Henderson County recently tested positive for EIA. A second round of screening confirmed the positive results. State officials are now testing additional horses that stabled with or live near the infected horses. EIA is a viral disease most commonly transmitted by biting insects. At this time, there is no vaccine or treatment. Although an infected horse can run a low-grade fever or become lethargic, often there are no clinical signs. A horse remains infected throughout its lifetime and can pass the disease to other horses. Owners of EIA-positive horses have two options: lifetime quarantine of the animal or euthanasia.

Marion County, OR
Confirmed case(s) quarantined
One Marion county horse has been hospitalized after testing positive for the neurological form of Equine Herpes Virus (EHV-1). The horse, which has been treated at Oregon State University’s College of Veterinary Medicine’s Large Animal Hospital, began showing acute neurologic signs on April 28 and was immediately referred to OSU. The positive EHV-1 diagnosis was made April 29. All horses at the Marion County property have been quarantined. The Oregon Department of Agriculture reports there is no indication at this time that the virus has spread to other horses beyond those being quarantined. Preliminary epidemiological investigations are underway. In all, there are 20 horses at the Marion County stable. The stable owner and all horse owners have been very cooperative and supportive of the disease control actions taken. The investigation shows that horses from the affected property have attended recent events held at the Linn County Fairgrounds in Albany on April 16-19, and the Oregon Equestrian Center in Eugene on April 25-26. While the risk to these horses appears to be low at this time, concerned horse owners are advised to contact their veterinarian.

Equine Herpes viruses
Maryland, MD
Confirmed case(s) quarantined
ANNAPOLIS, MD – A horse that was at the same breeding facility as a Montgomery County horse that was recently diagnosed with the mutant neurotropic form of Equine Herpes Virus (EHV-1) has tested positive for EHV-1. This second horse, which is still at the breeding facility, had no symptoms and was diagnosed as the result of lab tests. Both EHV-1 positive horses are under care by private veterinarians and are in strict isolation, according to protocol. The Montgomery County horse had been at the breeding facility for more than two weeks before returning home on Monday. While at the breeding facility and during her first day home, she exhibited no signs of illness. On Tuesday, the horse began showing mild respiratory and neurological signs and was seen by a private veterinarian, who reported the suspected neurological illness to the Maryland Department of Agriculture (MDA), as is required by law. Laboratory tests conducted by MDA confirmed the diagnosis. Following a Disease Investigation Protocol, MDA tested horses that were in close contact with the sick horse at the breeding facility. That investigation discovered the second positive horse. All horses that were exposed to the two positive horses are currently free of symptoms and are being monitored daily. All appear healthy. Both farms will remain under quarantine to ensure the virus is contained. As of today, MDA believes the virus is contained to these two farms and is not aware of any other EHV-1 cases in the state. MDA’s Animal Health Program continues to monitor the situation closely. Owners should contact their private veterinarians to arrange for EVH testing if a horse exhibits significant temperature elevations or neurologic signs. Veterinarians are required to report equine neurologic syndrome to MDA.

Equine Herpes viruses
Michigan, MI
Outbreak contained
EHV-1 Update for Friday, April 17, 2015: The number of EHV-1 positive horses in Michigan has remained at four. Two positive horses (1 was already euthanized) at the Livingston County quarantined index farm and two positive horses at a quarantined Saginaw County farm. There have been no new cases of EHV-1 since April 3,2015. In an effort to assist individual horse owners, whose horses are currently housed at the quarantined facilities, the Michigan Department of Agriculture and Rural Development (MDARD) has allowed three horses quarantined at the above Saginaw County premises to move to isolated locations, one each to Midland, St. Clair and Genesee Counties this week. The horses moved are not the EHV-1 positive horses mentioned above, but may have been exposed to EHV-1 positive horses. An isolated location has no other horses on the premises or within a quarter of a mile of the premises. The three isolated locations are also under quarantine. The reason for allowing horses to move from one premises to another while remaining under quarantine, is that horses continue to have fevers at the Saginaw facility, which restarts the 28 day count for horses that have no fevers or symptoms suggestive of EHV-1. Moving a horse to an isolated location allows that horse to be potentially removed from quarantine sooner than if it had stayed at the original farm. There are also an additional two premises that remain under quarantine, one in Ionia County and one in Saginaw County, where horses tested negative for EHV-1, but were exposed to the index horse and exhibited fevers and/or symptoms that can be seen with EHV-1. With the three additional secure location quarantines, there are now seven quarantines for EHV-1 in Michigan. All horses at quarantined facilities are under quarantine until all horses have either had no fevers and/or clinical signs exhibited that are consistent with EHV-1 for 21 consecutive days and have subsequently tested negative for EHV-1 or have had no fevers and/or clinical signs exhibited that are consistent with EHV-1 for 28 consecutive days.

ANNAPOLIS, MD (April 15, 2015) – A horse stabled in Montgomery County has tested positive for the mutant neurotropic form of Equine Herpes Virus (EHV-1) and is being treated by a private veterinarian. The horse had been outside Montgomery County for breeding for more than two weeks before returning home on Monday. The horse began showing mild respiratory and neurological signs on Tuesday and was seen by a private veterinarian, who reported the suspected neurological illness to the Maryland Department of Agriculture (MDA), as is required by law. Laboratory tests conducted by MDA confirmed the diagnosis. The horse’s condition is improving. Other horses at the farm are now being tested as are horses that were in contact with the ill horse at the breeding facility. Those results will not be available until tomorrow. Both farms are presently under a 28-day investigational hold while MDA inspectors perform additional epidemiological and infectious disease testing. Stables near the one where the sick horse resides have been notified of the situation and owners cautioned to monitor horses at their premises carefully. MDA’s Animal Health Program is monitoring the situation closely. Owners should contact their private veterinarians to arrange for EVH testing if a horse exhibits significant temperature elevations or neurologic signs. Veterinarians are required to report equine neurologic syndrome to MDA.

On March 19, MDARD was notified of a Livingston County horse testing positive for Equine Herpes Virus type 1 (EHV-1). Unfortunately, this horse had to be humanely euthanized.
As of April 2, 2015, two additional Michigan horses have tested positive for EHV-1. Both horses developed fevers and are under veterinary care. One of these additional positive horses is from the same Livingston County stable in which the index horse resided.
The second additional positive horse is at a separate stable in Saginaw County in which horses attended a March 7, 2015 event in Barry County also attended by the initial positive EHV horse.
There are currently four facilities under quarantine, including the two facilities to which the EHV positive horses reside, that are monitoring horses for signs and symptoms of illness as they have had exposure to the index horse and a fever >101.5 Fahrenheit.
MDARD continues to trace all contacts of infected horses to ensure no further disease transmission has occurred. Horse owners are encouraged to vaccinate their horses and to contact their veterinarian if a horse has a fever greater than 101.5.
