Location: Southwest Minnesota | Here is the latest post from the U of MN Equine Center:
4-3-14. A horse in Wright County, MN tested positive for Equine Herpes Virus-1 or EHV-1 today, April 3, 2014. To date, there have been 9 confirmed cases of EHV-1 in MN, WI and IA horses. We are encouraging all Midwest horse owners to quarantine their horses for a minimum of 2 weeks from the date of the last confirmed case of EHV-1. Currently, the quarantine extends to April 17, 2014. If additional cases are confirmed, the voluntary quarantine will be extended beyond April 17, 2014. For more information on EVH-1, view the recorded webinar at http://www.cvm.umn.edu/umec/EHV1info/home.html or visithttp://www.extension.umn.edu/agriculture/horse/health/equine-herpesvirus/index.html. For up-to-date information on confirmed cases of EHV-1 in MN, visit http://www.mn.gov/bah/horses.html#equine-herpesvirus. For information on how EHV-1 is being addressed at the MN Horse Expo, visithttp://www.mnhorseexpo.org/ehv.html. For information on biosecurity, visithttp://www.aphis.usda.gov/publications/animal_health/2011/bro_keep_horses_healthy.pdf.

| And another. And another... It goes on. People need to learn to stay home. From Anoka Equine:
EHV-1 UPDATE APRIL 8 - (TUESDAY):
FEEL FREE TO FOLLOW OR SHARE THIS POST. IT IS INTENDED AS INFORMATIONAL, WE ASK THAT IT DOES NOT BECOME A DISCUSSION BOARD. INDIVIDUAL QUESTIONS SHOULD BE DIRECTED TO [email protected].
Yesterday we tested a horse in Isanti County; this horse was neurologic and unable to urinate. This horse is at a large facility and that facility has been closed, no new horses have entered the property. This means it was brought in by a human in some way…on equipment, shoes, hands, tack, etc. This is an entirely new case and does have a high probability of having positive results, test results are expected back this coming Friday or Monday.
There is also a pending case in St. Croix County, Wisconsin with a high probability of being positive. Results are expected back mid-week Wednesday or Thursday as a guess.
COMMON QUESTIONS:
• People have been confused and are asking what constitutes “positive”? A horse is positive if they have BOTH a positive final test and clinical neurological symptoms. A horse that tests positive but is not showing symptoms is not considered a true positive and those horses are re-tested at about the 3 week mark.
• Can we test horses as a screening procedure, “just to be sure”? The answer is no. The laboratories and veterinarians are not testing random, normal horses. We will only do tests on horses from positive barns, horses that have been exposed to positive horses or those that are symptomatic.
• Yes, a seemingly normal healthy horse can indeed not be healthy and develop clinical signs later. This it the biggest reason for our 2 week “no travel” suggestion.
CASE UPDATE AS OF TODAY:
Horse 1: Chisago County, MN. – Positive on 3/8/14 – Euthanized
Horse 2: Chisago County, MN. – Positive on 3/8/14 – Recovering
Horse 3: Dakota County, MN. - Positive on 3/18/14 – Euthanized
Horse 4: Polk County, WI – Positive on 3/20/14 – Recovering
Horse 5: Hennepin County, MN – Positive on 3/21/14 –
Recovering
Horse 6: Freeborn County, MN. - Positive on 3/26/14 -
Horse 7: Wright County, MN. - Positive on 3/26/14 - Recovering
Horse 8: Iowa (horse visited both Freeborn & Hennepin Cty) –
Positive on 3/26/14 – Recovering and barn tests clear
with other horses.
Horse 9: Wright County, MN. – Positive on 3/29/14 – Euthanized
***Suspect case St. Croix, WI. Tested on 4/4/14 – Awaiting results
***Suspect case Isanti County, MN. Tested on 4/7/14 – Awaiting results

Location: Bastrop, Texas | This is frustrating as hell. On the other hand, when you read about this disease, it's pretty scary. This 2007 article from the USDA highlights the problem in eradicating EHV-1. Of a total of 403 horses "at risk" from 6 outbreaks between 2001-2005, about 1/3rd actually developed the neurologic form and once that happened, the mortality rate is quoted as 40%. Another thing in this article is that they claim that the neurologic symptoms may not appear for as long as 28 days from the onset of non-neurologic symptoms. In oither words, just because a horse has a snotty nose but looks OK otherwise, he might develop the signs of the neurologic form 28 days after he showed initial signs. Basically, the problem boils down to this virus mutating, but even though the article is 7 years old, it is concise and pretty informative. It does sound like Acyclovir or Valacyclovir MIGHT be helpful. Anyone interested should read this:

Location: never in the right place | we have 1 in Ct that I know of she is at my vets and my horse is there because he has some serious Lyme Disease issues and they put that horse in the barn with my horse because they both had a fever. Mine is NOT contagious. He spiked a temp of 105 and they think it could be the virus. great his body if fighting systemic and neuro Lyme and now this. |

Location: Minnesota | This is so frustrating! Thankfully I am not in any of the counties that these horses are in but those counties are close. My horses arnt going anywhere. There are still horse sales and shows going on and PEOPLE ARE STILL GOING. Its a scary situation. I also just heard from a friend this morning who sold her horse last week to a very well known barrel races and that horse is now out of state. Thankfully there was no horses at her barn with EHV-1 but that is not a risk I would of been willing to take. Hopefully there is some sort of handle on this soon. |

I agree...why can't people stay home...sit tight, for 3 weeks?? I was hoping this would be a short term situation, but if people keep on hauling, it will turn out to be a real firestorm. |

| Couldnt agree more. If we dont stop traveling, this will never end. People need to make the sacrifices and lay low. This includes horse sales, rodeos, stock events, shows, clinics, etc.
Its beyond frustrating to me. |

Location: Way up North | While I agree on the not hauling part they are saying one of the new cases they think was brought in by a human as it was a closed barn that has been following the no in/out procedures. They also posted they think the horse can have the virus for an extended period of time before developing neuro symptoms and thus then be tested and be positive. So these "new" cases could in fact be from the first wave. |

Knowing which barn this is referencing, it could be an exposure from something previous since it can take awhile for the neuro symptoms to activate. I dont think we can prove one way or another how this stuff is spreading but i think no hauling is still much needed right now until they can get control of it. |

| I don't want to stir the pot but I have a question that I haven't seen addressed. Maybe it has but I missed it. The horses that have tested positive does anyone know what kind of the yearly vaccine were used on these horses if any. Just wondering if there is a common starting point. It seems strange that it jumps from barn to barn that far away with the barns being closed. From what I have watched and read the life time on boot and clothing is only a few hours and shorter if exposed to sunlight. Just asking don't flame me. |

From what I have read and heard there hasn't been any talk about if the horses that got infected were up to date on their shot. The horses that are infected and their locations have been kept pretty hush hush except for the county that the horse is in. This whole matter is complicated by the fact that this can travel via cloths, boots and such. I know you mentioned that it only lasts a few hours on clothing but that's enough time to travel from one barn to another. IMO there needs to be a mandatory lockdock in order to fix it. There is always going to be someone who thinks their horses won't get it and will continue to travel. |

| No ones really addressed anything that specific. The earliest cases were before most people did spring shots as well. I understand that this is a different strain that the vaccine may not be 100% effective against, but I have to think it would help - kind of like the flu shot, it may not cover every strain every year, but most believe it helps. Our vet agrees.

I have all my shots done the beginning of April and I'm worried about having my vet out now. Its bad enough that I had my farrier out last week and now that I think of it, I shouldn't of had him come out. My herd isn't around other horses and I havent been around other horses or people with horses so I feel pretty safe.  |

| Tractor supply carries a couple of the recommended disinfectants. Talk to your vet about biosecurity and disinfecting before they come on the property.
How close to the hot zone are you? |

| I agree that we all need to stay home and I am. My horses haven't been anywhere since Oct. But I believe there is more to it than contact, and to stop it we need to look at all avenues. |
