EHV1 outbreak information

OC Meeting with State Veterinarian - Thursday

Dr. Fowler, Head Veterinarian of the California Department of Food and Agriculture, and the vet who is overseeing the quarantine at RSV, is flying in to Orange County. He is coming to answer questions, and relieve any concerns you might have regarding the EHV-1 virus.

Sorry about the late notice, we know, however we just found out ourselves. He will be here TOMORROW (Thursday) at 12:00 p.m. at STONE FIELD PARK, SJC (near the Mission, at the corner of Lazanja and Camino Capistrano).

Please help us get the word out to ALL horse owners!

As of today, there were three new cases of neuropathogenic Equine Herpesvirus-1 (EHV-1) have been confirmed at Rancho Sierra Vista. There are a total of 8 confirmed positive horses on the premises. At this point in time, only one of the eight cases has displayed neurologic signs. All exposed horses on the property are being monitored and enhanced biosecurity measures have been implemented. The source of the outbreak has not been identified. The initial epidemiologic investigation reveals no link to the three 2011 California neuropathogenic EHV-1 incidents.

Such a bummer. I boarded there two summers ago. Prayers that this gets resolved soon!

As of today, two additional cases in Orange County. This brings the total to 11, including one horse that had to be euthanized.

Did anyone go to the meeting/information session?

Anyone know what barns/trainers have been affected? I believe an initial rumor I heard was that it started with a western horse.

OC Update and now case in Riverside County

Riverside is a pretty big county that includes Thermal, Temecula, Corona, etc.

Maybe that’s as good as we’re going to get. The trainer that went said it was mostly common sense, be careful, and don’t panic and they went over the biosecurity protocols. So, much like the two meetings I attended four years ago and still have the notes from. Guess it’s time to drag out the folder.

I pulled this off of a FB post today…

Vessels Stallion farm is in Bonsall, so SD not Riverside. Maybe they were just passing the info along? Or the CDFA could be geographically challenged.

I didn’t attend the meeting as I got stuck in the office. But according to friends who went it was mainly focused on bio-security in preventing the spread of the virus and all of that. We were hoping to get info on which horses specifically are sick since the guy who was doing our blanketing works at Rancho as well as our barn. And we were worrying about that.

The initial confirmed horse and the one displaying neuro signs is an english horse. He is doing better last I heard. As for which barns are affected, from the horses I’ve been told are confirmed it is a variety of barns are RSV but most are all stalled in the same general area. With all of this I just keep thanking my lucky stars I moved my horses! But at the same time I keep praying for all my friend over there.

I agree it does look like they just are reposting the info from the CDFA site.

INDIO HORSE TESTS POSITIVE FOR EHV-1, NEUROPATHIC STRAIN
January 24, 2012 By Dr. Mike Manno, DVM Leave a Comment
The polo horse that exhibited neurologic signs over the weekend and was euthanized Monday night has tested positive for EHV-1 at the U.C. Davis Lab. While other confirming tests at different labs are still pending, this single positive test warrants immediate action by the California Animal Health officials.
With help from the staff at Empire Polo Club, we have instituted a complete quarantine of all horses stabled near the Forum field. Entrance through and exit from the gate near the Empire arena will be monitored and restricted to only essential personnel tending to those horses. The track next to the Forum field will be available only to the horses in the quarantined area. No other horses or people will be allowed in and out. State veterinarians from Sacramento and the Ontario branch of the California Animal Health and Food Safety division will meet with us Tuesday morning to assess the scope and duration of the quarantine process. At this time, the greater effect on the polo season or HITS horseshow cannot be determined. This will be decided by and is completely under the authority of State officials. This will also be determined by further testing results and/or the presence of additional infected horses, should any appear.
We are asking all other horse owners to remain in their respective areas as much as possible. We will continue to update as needed and as new information becomes available. Thank you for your understanding and cooperation.

Del Mar Horsepark-no in/out and Thermal Meeting

Thermal Meeting:
JANUARY 25, 2012

Thermal HITS - Good Horsemanship Precautions, EHV-I

A noon informational meeting today at HITS Thermal laid out precautionary information relating to the recent west coast EHV-I outbreak. In the spirit of horse safety and care, Tom Struzzieri and his staff called a noon get together for trainers and California State Vets to exchange information.

Four California State Vets are in town to investigate a positive horse at Empire Polo Club (17 miles from the HITS grounds) that was euthanized on Monday. They emphasized that the exposure potential for horses on the HITS Show grounds was extremely „low risk‰. The polo club has been quarantined and locked down for 21days of monitoring and cautionary actions.

HITS staff has instituted precautionary actions.

*No daily ship-ins allowed effective immediately.
*Upon arrival of horses to the show grounds, full disclosure for each horse as to where it comes from, where it has been and what contact with other horses it has had.
*Keep control of contact among horses.
*Procedures laid out for horse owners to take the temperature of each horse twice a day. An unexplained fever of 102 or higher should be reported to Dr. Peters, Hagyard Vet Clinic on grounds, for evaluation.
*In a precautionary measure, horses in question will be relocated to one of several isolation stalls currently being erected on the grounds for further evaluation.

The California State Vets emphasis that the risk of exposure is extremely low for HITS competitors and stated that normal precautionary measure should be continued. They reiterated there is no reason to panic and over react.

When directly asked, „Is the HITS show a safe place to bring horses to compete for the Circuit?‰ ALL four of the vets quickly and emphatically answered, „YES, the risk is low and being monitored by all of us and the State. Information will be quickly relayed to horseman. Keep checking the California Department of Food and Agriculture web site for updates.‰

For more information go to www.cdfa.ca.gov , click on the EHV-I on the top right. The state vets will keep the updates current.

HITS will keep you informed of any new information.

Del Mar Horsepark (via the SD CDS chapter):
Due to the EHV-1 outbreak, Del Mar Horsepark is abiding by the recommended 21-day shutdown, which means horses will not be allowed to enter the facility for 21 days, and horses that leave the facility will not be allowed to return. As a result, our February show must be cancelled. At this point, we expect to hold our June show. We have several viable options that we are exploring and will make a formal announcement once we have something finalized. Those who have already paid for the February Show will receive refunds. Questions? Contact Show Manager Lisa Blaufuss.

OC/Indio (Riverside County)

1/25/2012 Update. One new case in OC (same barn as rest). No new cases in Indio. http://www.cdfa.ca.gov/ahfss/animal_health/equine_herpes_virus.html

The polo people are taking this seriously. Quarantine zones at the polo club with separate exercise areas for each and no movement between zones. Quarantine of several block area. No games or practices until 21 days after the last case. There’s an update every day. I think the one from yesterday talked about the zones. Here’s a link today’sL

Thanks for the continued updates Peggy !

Thanks for the continued updates Peggy ![/QUOTE]You’re welcome.

At this point I’ve decided that the best source of information on the Indio “outbreak” is the Polo Club page which seems to get updated daily: http://empirepolo.com/

This is in addition to the official state site:

Let’s hope this thing stops soon.
