March 3, 2016: The EHV-virus emergency in New Mexico appears to be winding down, but Utah horse owners are cautioned to continue to not send or receive horses from the quarantined barn there.  As of today, the quarantine has been lifted at Frontera Training Center. As for the Sunland Raceway, only one barn remains exposed and under quarantine.  No new positive cases have been confirmed since February 24th. To date a total of 54 horses have been released from isolation.    For more information, contact the Utah State Veterinarian, Dr. Barry Pittman (801) 538-7162.

 

February 22, 2016  We have had no new positive cases for the past 5 days.  In total, 20 barns have been released from “exposed” to “non-exposed” status. Twenty six horses have been released from isolation based on negative swab and whole blood samples.
 
All in all, not a bad day in the Land of Enchantment.

Updated February 18, 2016  Today’s tally of EHV-1 confirmed positive horses is 74. Two of the horses confirmed today re

side in Texas; they belong to a trainer who has horses at Sunland. The information on these two positive horses was submitted to the Texas Animal Health Commission for follow-up.
To date, 17 barns have been released and 10 barns (including Frontera and Sunland) maintain their exposed status.

 

Updated February 16, 2016:  The number of horses diagnosed positive for the EHV-1 to-date is 70. The number of horses that have been released from isolation is 15. Currently there are still 15 exposed barns.  The surrounding facilities have not had any positive cases and have been released from quarantine after 21 days with no movement on or off premises.. Both Frontera and Sunland Park remain under quarantine.

Updated February 11, 2016:  62 confirmed positive horses , 20 exposed barns, and 6 of the horses have been euthanized for neurological symptoms.

To clarify, the quarantine is a large perimeter that includes Sunland Park Racetrack and Frontera  Training Facility. 45 of the

positives are from Sunland and 3 positive horses are from Frontera.

Each barn in Sunland and at Frontera is taking temperatures twice daily and turning in their temp sheets daily. A barn that has a positive horse is placed under its own “exposed” quarantine and the positive horse is moved to an isolation barn. That quarantined  barn is restricted until 14 days have passed from the last positive horse being removed. We are currently going to start releasing those individual barn quarantines that have had n

o positive cases in the past 14 days.

For the horses that have been in isolation, they are being retested (swab and blood) 14 days after being in isolation. If they are negative, they are released back to their barn. If they are positive they stay in isolation. Quarantine for Sunland and Frontera stays in place until all positive animals have been released to their barns based on negative test results.
The quarantine protocol being followed is the “IDOHC EHM Incident Guidance Document” established in Sept 2015. I have attached it to this e-mail.
 
Thanks to all of you who have offered pointers on incident management and your support.
Sincerely,

New Mexico EHV-1 Update     - Feb. 3, 2016
Currently there have been 44 positive sampled horses (out of 129 samples), 19 barns exposed, 5 horses euthanized for welfare purposes due to severe neurologic signs, and one active trace out to Turf Paradise Racetrack in Phoenix, AZ. 
A horse that was moved out of New Mexico, and traveled to Arizona, developed severe neurologic signs and had to be euthanized.  The animal came from the barn that the index case in New Mexico originated from.  Two other horses that accompanied the deceased Arizona exposure animal are currently under quarantine and have not shown any signs of EHV-1 to date.

Jan. 27, 2016
(Salt Lake City)  Utah horse owners are advised to not accept shipments of equine, nor send their equine, to Dona Ana County, New Mexico without special permission from the Utah State Veterinarian’s Office.  

Sampling has confirmed Equine Herpes Virus -1 (EHV-1) in a total of 18 horses at Sunland Park Race Track near Las Cruces, New Mexico.   New Mexico veterinary authorities have quarantined 13 barns at the facility following the initial finding of one horse with neurologic symptoms.  The initial horse was euthanized Jan. 21, 2016.  All positive animals are confined to an isolation barn.


EHV-1 is an equine disease not known to affect humans.

All animals on premise are being carefully monitored and their temperatures are being taken twice per day.  Any additional animals suspected of having the virus are sampled by nasal swab and whole blood.  New Mexico State authorities have quarantined three other local horse training centers in the area. Horses in surrounding areas have tested negative.   
 
All equine owners and veterinarians in Utah should be aware of the current situation and maintain close contact with the Utah Department of Agriculture and Food’s Animal Industry Division for current information before moving horses into or out of Dona Ana County, New Mexico.  

Horses from Dona Ana County, New Mexico will be restricted from traveling to Utah without special permission from the Utah State Veterinarian’s Office.  A statement on all health certificates reporting the temperature of the animal and no potential exposure to this quarantined facility or other animals that have had exposure to these facilities within the last 10 days will be required for animals leaving Dona Ana County, New Mexico.


Horse owners who have recently had horses at Sunland Park are advised to contact their local veterinarian for medical questions.
