Until this rhino situation plays out, my horse will not leave my farm.  Not taking any chances.

They make a vaccination for that.


Yes I know, she is current on her 5-way vaccine, which includes EHV-1 (Rhino).  But, I will not take any chances by exposing her to another horse, clean or infected.  JMHO

They do in fact make a vaccination for the EHV-1 but the vaccination does not cover the nurological part of the disease and even if your horse is vaccinated for EVH-1 they can still get it.

That's right Rhonda.  Most people that I know are canceling all events where horses will make contact.  In fact, it can be transferred by a carrier horse that shows no signs of contacting the virus or even human contact, tack, etc.

I know of one horse that was put down this past weekend that was not at Bucksnort.  However, her pasture mate was down there and apparently transmitted it back to her.

Some people aren't taking it as searious as they need to. I have done tons of research and if people don't take it more seariously it will turn into more of a problem than everyone thinks. Hopefully there will be a vaccine soon before it becomes a damper on summer trail riding. We have canceled our Memorial Day trip

Ron pretty sure I know the horse you were talking about if it was in Wilson Co bc my husband was the attending vet. The pasturemate that went to Bucksnort was given the pnuemabort (rhino) vaccine earlier in the week and the state vet believes that is what has saved it. We have given all our horses and are recommending the pnuemabort vaccine manufactured by fort dodge. It isn't 100% but it has worked so far in this case. Hope that helps, but our horses aren't going anywhere.

Yes Amanda that is the mare that I am speaking of.  We always gave Pneumabort-K to our pregnant mares in the latter stages of pregnancy.  Do you know if that is the same vaccine that is in the 5 or 6 way shots from Ft. Dodge?

Rhino is in the 5 ways, but not enough to help with the neuro type. The shot you give to pregnant mares is what you want to give. The pnuemabort K by fort dodge is 10 times stronger than what is contained in 5 way shots, and has so far kept the rest of that herd from coming down with it. The only catch is just like with the mares it has to be boostered (according to label every 4 weeks), but I think we are gonna go with every 8 like you would a mare.

I have just vaccinated all my horses with Pnuemabort and already given them 5-1 shots.  We have just returned from LBL two weeks ago and Big South Fork this past weekend before I knew about this problem and I understand that symptoms may not show up for 28 days.  Is there a way to draw blood from a horse to determine if he is infected with EHV-1 - or show that he may be a carrier (and not sick)?  I am concerned about riding with someone's horse that could be a carrier or maybe purchasing a new horse to bring home.


Also, if a horse tests positive for EHV-1 and is obviously not sick - does this mean he is a carrier and does he have to euthanized and/or quarrantined for life as in a coggins carrier??


There is a blood test that tests for anitbodies. IDK about the carrier issue, but I wouldn't be bringing any new horses into my herd right now.

Latest update from TN dept. of Ag

Suspected Equine Herpes Cases Reported in Tenn

Updated 5/16/12: There have been no new reports of suspected cases of Equine Herpes Virus (EHV-1) stemming from the Bucksnort Trail ride held April 23-30 in Humphreys County since the last update on Monday, May 14. To date, the Tennessee Department of Agriculture has received a total of nine reports of suspected or confirmed cases of EHV-1 in Tennessee horses. The neurological form of EHV-1 has been confirmed in one case. Six of the suspected cases have been confirmed as showing clinical signs of the disease and are being isolated and monitored. In two cases, horses have been humanely euthanized.

The State Veterinarian's office has obtained a list and has contacted each participant to make them aware of possible exposure. Restrictions on horses that attended this event are being evaluated on a case-by-case basis. The event drew approximately 100 horses from multiple states and animal health officials have also been notified in those states.

Transmission of this disease is primarily through direct exposure to an infected horse. The spread of this disease can be effectively controlled through good biosecurity practices and isolation of affected horses. Other trail rides and show events are not affected at this time; however, event organizers and participants should use their discretion in planning activities and implement good biosecurity measures as a precaution.

Recommendations for Horse Owners Who Attended the Bucksnort Trail Ride:

If you participated in this event, as a precaution you should not move your horse from your premises for 21 days after potential exposure which occurred April 23 - 30.

Isolate and monitor your horse's health for 7 to 10 days by obtaining a rectal temperature twice daily during this time. Contact your veterinarian if your horse's temperature exceeds 101.5 degrees Fahrenheit or if other clinical symptoms develop.

Consult your veterinarian about preventative health measures such as vaccinations.

Recommendations for Veterinarians:

Horses exhibiting clinical symptoms of EHV-1 should be reported immediately to the State Veterinarian's office at 615-837-5120. A quarantine order will be issued to isolate and monitor the affected horse for either 21 days with testing or 28 days without, following resolution of symptoms.

Symptoms of Neurological EHV-1:

Equine Herpes Virus is highly contagious among horses but poses no threat to humans. The symptoms in horses may include a fever, nasal discharge, wobbly gait, hind-end weakness, dribbling of urine and diminished tail tone. The virus is easily spread by airborne transmission, horse-to-horse contact and by contact with nasal secretions on equipment, tack, feed and other surfaces. Caretakers can spread the virus to horses if their hands, clothing, shoes or vehicles are contaminated. The virus can cause aborted foals and can be fatal in some cases.

Biosecurity Practices:

Horse owners should practice good biosecurity such as using your own trailer and equipment, not letting your horse touch other people's horses, disinfecting shoes and equipment, washing hands after helping others with their horses and limiting access to your farm. A downloadable brochure about horse biosecurity is available from the USDA Animal and Plant Health Inspection Services at http://www.aphis.usda.gov/publications/animal_health/content/printa....
