Many of our CHSA members have asked to be kept informed if the Equine Herpes Virus (EHV-1) appears in Connecticut.  Below is a statement from The Connecticut Horse Council, Inc on the EHV-1 in Connecticut.

The Connecticut Horse Council, Inc.
CHC ALERT-EHV-1 status in the state of Connecticut

For Immediate Release 1/3/2007:

The Connecticut Horse Council, Inc. has been actively watching reports of an outbreak of the neurological form of Equine Herpes Virus (EHV-1) in a number of states, including Florida and California. Due to this time of the year being the height of show season for several disciplines, many horses are being transported between states. This increases the potential for transmission of this virus to other horses.

As of December 24, 2006, a horse at Fairfield Equine Associates in Newtown Connecticut, developed a fever and was tested. It has since been confirmed as being positive with EHV-1. CHC has spoken directly to the veterinarians at FEA, as well as Connecticut state veterinarian, Dr. Mary Jane Lis.

We have received the following information:

As of this date, there has only been one horse confirmed with EHV-1 in Connecticut. This horse has been quarantined and will remain in strict quarantine until such time as the state of Connecticut determines it is safe to be released.

The horse in Connecticut was originally shipped in from Vermont on December 13. It was at FEA for another procedure, and became ill after arrival. A nasal swab was taken and it was confirmed with EHV-1.

FEA has been working closely with the state of Connecticut and USDA/APHIS. The state does NOT feel that this horse has any connection with the infected horses in Florida. State Veterinarian Dr. Mary Jane Lis has been working closely with the Connecticut Veterinary Medical Association (CVMA) and they have been sharing information with veterinarians throughout the state. Veterinarians’ working on the case feel potential exposure to other horses was limited because it was caught quickly.

If there are any additional outbreaks discovered, veterinarians will take appropriate actions, and the state will be notified. Additionally, conversations have been taking place between the Departments of Agriculture throughout the New England states. It should be noted that EHV is not considered a “reportable” disease, so it will not be tracked by USDA, but instead will be monitored by the individual state veterinarians.

There is currently NOT a statewide quarantine in effect for Connecticut. There is a voluntary quarantine in effect at FEA. FEA clients who may have had horses exposed to this horse have been notified. These horses are being monitored by FEA veterinarians.

Dependant upon your individual situation, it is important that you work closely with your veterinarian in order to determine if additional vaccinations are warranted. Also, for those facilities that have horses shipping in from other states, it is recommended that you institute standard safe handling procedures, such as not sharing equipment or items such as buckets or blankets. Please see the attached links for additional information about virus transmission and biosafety procedures.

For those individuals shipping horses to other states that may be affected, you should consult with the receiving state’s Department of Agriculture for updated information.

CHC takes this issue very seriously. We will make all information that we can verify available to horse owners as we have it. We will continue to be in close contact with both the state of Connecticut and CVMA.

If you have additional questions, please speak with your veterinarian. You may also contact CHC president Amy Stegall Additionally, you may also contact the Connecticut state veterinarian Dr. Lis at 860-713-2505.
