Hey Folks -- Put this together and posted it on the "Warning" thread last night.  Decided to make it a Fresh Thread, so that I can easily find this post and edit and update as we get more info:  

~Last Thursday, Corrine Dean trailered #763 home (from the 3/17 sale).  the mare came off the trailer panting and shaking.  She quickly began to stagger and fall, the vet was called, the mare was euthanized.  The mare showed signs of shock, oral membranes were black, the vet diagnosed a bastard strangles/pnuemonia.  No necropsy was done.

~Sometime over the weekend, #775 (3/17 sale) was shipped to Pocono Eq. Center. (Ed:) This horse didn't make it to Pocono Eq.  The driver stopped for coffee and found him dead on the trailer.  It's my understanding that a necropsy was going to be performed, results now follow:  

3/24--UPDATE ON #775 -- Beverly Peffer Necropsy Report came back on "Angels Heart" aka Gabriel boy that died in his trailer to his QT dest. Upper respiratory moved to pneumonia.

 So, NOT EHV1. THAT is good news.  Maybe it is less spread than we feared.  Looks like perhaps that two were NOT part of this outbreak, but sadly pnuemonia related.

~Information was released today (3/23) that Rachel Sherman had NJ State officials at her place, that two cases of EHV1 had been confirmed.  Apparently a boarder's horse died early last Thursday (3/18) and another followed a couple of days later.  Both horses owned by same owner.   They were apparently stalled in/near the quarantine barns.   After hearing this, it was obvious that the infections did not begin with the 3/17 group of horses.

~I spoke with Rachel Sherman late this afternoon (3/23).  State officials spent the day theres, checking infections, Coggins reports, timelines, etc.   It is concluded at this point that the point of infection began from the 3/3 and/or 3/10 Sales.   Several horses at Rachels have been diagnosed as infected. . . They are:

435 - Black/white Stud from 3/10
414 - "Herbie" 5 yr gelding fr 3/3 -
363 -  Bay Walker mare  fr. 3/3 - Sadly I understand this mare is/has been put down.
364 - 6 yr, 14.1 hh, welsh-cross mare, pregnant.  May have been the initial carrier
This mare WAS at another barn for a week prior to arriving at Rachel's.  The state IS aware of the fact and they were going there once they were finished up at Rachel's today.
 
Rachel's place is under state quarantine for 21 days. That 21 day period begins from the date of the last known case.  If others sicken, the clock begins from the date of the newest case. 
 
Additionally, #449, pulled and "home" may possibly have the herpes virus, upper respiratory symptoms, but doesn't seem to be neurological, she has been tested today - Nothing is confirmed, Edie is being pro-active at this point, just to confirm or rule out for peace of mind.
 
~~~3/27 UPDATE:   VET TEXTED ME THIS A.M. -- DUBLIN IS NEGATIVE!!! HHER has #436, black/white 2 yr old colt from 3/10 - -while he's been sick w/upper respiratory symptoms and has been under a vet's care, he has not shown any neuro signs.  We ran a nasal swab for strangles last Thurs.  that came back clean, only a staph infection.  Based on what's going on, I called our vet back out today, he conferred w/the state and nasal swabs and blood were taken for testing for EHV1.  'Dublin' has been quarantined since arrival, we are taking every precaution - -bleach is our new best friend, though we are looking into something stronger.   We will be be self-quarantining in the interim, no horses in or out.  Sadly, we will NOT be attending the Camelot Sale tomorrow.
 
~As reported on Facebook, Frog Pond Draft Rescue, while having no cases, has chosen to shut their doors for now, in the interest of safety.  They have a vet coming tomorrow to test all horses who have entered the property since March 1.
 
~I've heard that Voices for Horses in Ohio may have two cases?  That is unconfirmed at this end right now folks.
 
~Now, there have also been posts and rumors of "Postive EIA" tests.  That is unconfirmed.  In a couple of instances, those posts were later found to be erroneous, the writers had their "initials" confused--but the posts were not removed or deleted, so the rumors persist.  Regardless, there have been no positive Coggins' out of  Camelot.  If there had been, they would have been shut down.  The state works that fast in those cases.  
 
Please do not panic - -if you have Camelot or any other auction horses from anytime in the month of March, I strongly advise you to contact your vet and arrange for nasal swab/blood testing.   Please note that there may have been cased in/from PA, but this has NOT been confirmed.  (ed:) Calder Racetrack in Florida was temporarily closed as a precaution--news, as of 3/22 was that the horse was NOT EHV1.   So, this is NOT specifically isolated to Camelot, it's out there right now folks, it seems up and down the East Coast in "pockets" at this point.
 
Do not Transport horses if you do not need to -- don't try to "sneak" anything in or out, just have the horses sit tight where they are.  We need to contain and treat any potential cases where they are.
 
~~~~~~~~~~~~~~~~
 
To put everything in one place, this is what Bev Dee found out today - -
 
I called Dr. Kennedy's office...she is the Dr./one of the Dr.'s that was at Rachels (not sure if there was more than one Dr. there).  Left her a message. 
 
Dr. Kennedy called me back.   Very nice woman.  Very concerned about how contageous EHV-1 is.
 
I said to her, "I purchased two horses from the 3/10 Camelot auction.  They left the auction on 3/15.  I was told about the QT at Rachel's farm.  Do I need to be concerned?"
 
While she never directly confirmed that any of the horses that are infected were from Camelot, she did say that my guys should be fine, but to have them tested just to be sure. 
 
These are the points she made. 
 
She said any horse that could have been exposed should have both nostrils swabbed ... a deep swab, and have the serum blood test done as well.
 
(3/24:  Several have been told by State that is is NOT true)She said that the NJ state vet's office will test the nasal swabs free of charge if your horse came from one of the Camelot Auctions in March since some ("bold" added by lisa) of the horses that tested positive thus far came from there.   Just have your vet get in touch with their office.
 
The horse can test positive and show no clinical signs.
 
The horse can test positive and not become ill.
 
If the horse tests positive, even though he shows no clinical signs after the incubation period, and the virus does not manifest in him, he still carrries it the rest of his life.  If his body is "stressed"  in the future, the virus could manifest and he would be contageous to others around him at that point.
 
She added, even though the horse may not show any clinical signs even after the incubation period, they could still be shedding the virus, so the contagen is still in the environment they occupy for up to 30 days. 

Bev

Thank you Edie for your research on EVH1  - -

Info from UC Davis -- http://www.vetmed.ucdavis.edu/ceh/ehv1_sick.cfm

There's DEFINITELY a ray of hope here - - - 

EHV-1 How to Handle a Sick Horse

Isolation of sick horses and early determination of the cause of their symptoms is very important. It is prudent to determine if the horse has been around horses that may have been in a place where EHV-1 has been documented to occur. Infections other than EHV-1 can also spread by horse-to-horse contact, so keeping a horse with a fever isolated is a very good practice in any case.

If your horse develops fever, respiratory signs or neurological signs, immediately notify your veterinarian and do not move the horse or horses in the immediate area. Alert those who have horses in the adjacent area to cease all movement of horses in and out of the facility until a diagnosis is confirmed by testing. If horses are exposed and then travel to a new stable or show, the infection can spread to other horses at that new location.

EHV-1 does not persist in the environment for a long time, but disinfection of premises, stalls, trailers and so forth is indicated. If you handle a horse with EHV-1 and don't wash hands or change clothing, you may spread the infection to other horses. A solution of 1 part chlorine bleach to 10 parts water is effective for decontaminating equipment and environment.

And from http://www.smcmsar.org/ehv1.html in regard to an outbreak in 2007, in part . . .

There is NO vaccine for the neurogenic form of EHV.   We do HOPE, but are not convinced that there is some cross over of resistance in the horses that are current on the Rhinopneumonitis (EHV) vaccines and we as a community are recommending that horses that are out showing were vaccinated within the last 3 months.  There are some vaccines that are better than others because they have a higher antigenic load (like pneumabort), but there are no vaccines specific for EHV-1.  Dr. Dave Wilson at UC Davis is not recommending that horses be vaccinated with vaccines that have a high antigenic load.  It is hard on horses and it is not given for this purpose. They are trying to develop a vaccine....

Some vets are giving immune stimulants such as Eqstim and Zylexis. Zylexis is $55.00 per shot and it is in the muscle.  EqStim is IV and is less (about $40 a shot), but you will have an easier time giving the Zylexis because it is IM.  

From a conversation with Dr. Madigan (UC Davis) - from the same site:

  • Horses are infectious when they are highly febrile and very sick. He said that the quick response & voluntary quarantine by Dr. Browning, barn managers and owners means that the whole thing will probably begin and end within 21 days and be over. The absolute best thing to do is isolate the sick horse immediately. He commended their work. (Interesting: He said he's seen instances where horses have been dragged out of barns, too sick to walk, and still have not sickened a single other animal in the barn).
  • If you are handling a very sick highly viremic horse, you should take a shower and wash your clothes before handling another horse, as a precaution. If you've been in the stall with the horse, in contact with its bodily fluids, you could transmit it for the next couple of hours. But if you are NOT handling a sick horse, you do not pose a risk. He said it is not spread like a cold or flu but like any other herpes virus (like nuzzling/kissing, sexual contact, etc.) Nor is it spread through casual exposure on clothing, shoes, tack etc. as has been rumored.
  • Scientists have exposed healthy horses to a virulent virus from sick horse (i.e. rubbed their noses with mucus) -- and nobody got sick. So there is some natural resistance in the population.
  • It is a newly recognized strain but not a new strain. It has been found in 35-year-old stored specimens.
  • There is some data showing that it is endemic and can be found in low levels of 25% of the general population, not infectious and with no symptomology. Many horses have been exposed and have not sickened. The mystery is why it flares up and turns fatal.
  • Fatality is not related to immune system compromise of horses with long-harbored virus. (None of the immune-deficient horses in Davis's ICU have ever gotten it.) They don't know why it sometimes is such a quick killer.

    Thank you, Lisa for taking time to put this together.  Our Boys will be tested as a precautionary measure.  I will post the results once we have them. 

    Contact information below for State Vets from states that we are aware "could" have cases of EHV-1 based upon where we know horses from Camelot went this month.  Please don't just call for "information" or "updates".  Call only if you have a horse that came from Camelot in March...this includes horses in foster care that were never at "your" property if you are a rescue.  A link to a complete list of state veterinarians (updated for 2010) is at the bottom of this email.

    OK, this is the deal. 

    I just finished speaking with Monica Carper of Camelot Sales.

    They normally bleach down the barn weekly as part of their protocol.  Had already done so before the positive-EHV1 cases came to light, afterwards, they did it again.

    There have been rumors of the water troughs "being filthy" - -- I always recognized the brown stains on the bottom of the tubs as being iron stains from the water.   We had the same problem here until we installed a water softener to the barn's well because I couldn't stand it anymore.   Now, AS FAR AS THE "Filthy/foamy" water. . . they, as part of their regular protocol, add Terramycin to the water, an antibiotic. as a regular precaution.   So, it's not 'filth', it's antibiotic.

    As far as the losses of #763 and #775, they too felt that they were pnuemonia cases, had specifically ID'd #775 as a pnuemonia before he left.  They were caring for him, and had suggested that he not ship.   They've got enough experience with these sicknesses in transient horses to recognize them when they see them.

    I confirmed with Monica that as of today,  there have been no other confirmed cases of EHV1 in any horses other than the ones located at Rachel Sherman's barn--so hopefully it is contained.   

    Now, Camelot DID have to give the NJ Dept. of Ag a list of all of the horses from March and who purchased them.  DO NOT PANIC if the NJDA contacts you. It is a part of their protocol to trace/track the horses and confirm whereabouts and health.

    Dr. Nancy Halpern, of the NJDA is apparently pulling her hair out with all of the phone calls.   She and her staff are trying to do a difficult job, let's give them some space so that they can get it done as quickly as possible.  I don't know about you, but I'd rather have them working on our samples than playing 20 questions on the phone.  . . As I noted above, if you have a March Camelot horse, they will probably be contacting you.

    If I think of anything I left out, I'll add it to this post.

    FREQUENTLY ASKED QUESTIONS

    EQUINE HERPES VIRUS-1

    February 17, 2006

    J. Liv Sandberg Dr. Larry Bauman

    UW-Madison UW-River Falls

    Equine Extension Specialist Extension Veterinarian

    Q. What is Equine Herpes Virus-1 (EHV-1)?

    A. Equine Herpes Virus (EHV-1) is a contagious viral disease of horses that can cause

    respiratory disease, abortion and occasionally neurologic disease.

    Q. Is there another name for Equine Herpes Virus?

    A. Rhinopneumonitis or ‘rhino’. It is a herpes virus that is common among horses.

    Q. How is the EHV-1 disease spread?

    A. Aerosol (airborne) and fomites (feed, clothing, boots, hands, etc.)

    Q. Can EHV-1 spread to humans?

    A. No, but people can transport the virus on their clothes, boots, etc.

    Q. Can EHV-1 spread to other species of animals?

    A. No

    Q. What are the clinical signs or symptoms seen with EHV-1?

    A. Respiratory disease, abortion and occasionally neurologic disease (lack of

    coordination, inability to stand, etc)

    Q. Are these clinical signs similar to any other equine diseases we have in our horse

    population?

    A. Yes. Equine Influenza Virus may cause respiratory disease, Equine Viral Arteritis may

    cause abortions, and West Nile Virus may cause neurologic disease

    Q. If my horse has some of the above clinical signs, will I be able to tell which

    disease he/she may have contracted?

    A. No.

    Q. Is there a vaccine available to help prevent the spread of EHV -1?

    A. Yes, but it doesn’t directly protect against the neurologicl form of the disease caused

    by EHV-1.

    Q. My horse is up to date on its vaccinations, including EHV-1, can my horse still be

    at risk of contracting the disease?

    A. It’s possible, but horses that have not been vaccinated are at a much higher risk.

    Q. Will EHV-1 affect all of my horses or are some of my horses at more of a risk of

    contracting the disease?

    A. Young, old, weak, high exposure, immune challenged, and stressed horses are more

    likely to get sick.

    Q. How long will it take for my horse to show clinical signs of the disease after

    her/she has been exposed to the disease?

    A. Usually 3-7 days following exposure (range: 2-10 days)

    Q. How long can my horse be contagious and potentially spread the disease?

    A. Horses can shed the EHV-1 from the onset of clinical signs until 1-2 weeks after the

    clinical signs are gone. A 21 day quarantine period following the disease is

    recommended.

    It has been almost 2 months since we have taken camelot horses so i think we are safe.

    This thread really drives home the point about suitable quarantine arrangements- most horses going through auctions often have traveled long distances and gone through other auctions, coming in contact with who knows what along the way. This is not an isolated Camelot problem- Frank runs a good sale- it is an auction problem.

    Quarantine protocol must be followed closely- and QTd horses must be kept SEPARATE from other horses- "Near" just doesn't cut it.

    My thoughts are with all of those generous souls who offered to give these horses a fresh start, and those who are dealing with the sick ones......

    Please note that he said that they are "presumptive positives", that means that all of the tests are not back yet, but presumed to be EHV1 based on what they have so far and symptomology.  What do you do?  30 days Quarantine.  Bleach is your  best friend--a 10% solution.  Spray your clothes, shoes with Lysol when leaving strange barns or areas.  Use good Hygene. 
     
    Again, if you have a March-Camelot horse, they will be calling you, DO NOT panic if you receive a phone message from a NJDA vet.  They're calling to check status of the horse at this point.  That is all.

    Date:   March 24, 2010

    Re:     Possible EHV Outbreak

    The New Jersey Department of Agriculture, Division of Animal Health is investigating a possible outbreak of Equine Herpes Virus 1 (EHV1). One horse tested presumptively positive and 3 horses have been euthanized with clinical signs consistent with the neurological form of the disease. The farm where these horses were stabled is under quarantine, as is another farm with epidemiological contact with the index farm. Both farms are in Monmouth County.

    The state is investigating all movement related to this incident and will take all necessary measures to protect horses in New Jersey and other states. The Division of Animal Health Laboratory can test horses for EHV1. The samples needed for EHV testing include:

      • Nasal swab in viral transport media (highly desirable) or 1 ml of saline (less desirable).
      • Blood in purple top tube (minimum of 10 ml of blood required)

    Veterinarians should call 609-984-2293 for further testing information.
