The University of Calgary, Faculty of Veterinary Medicine, is conducting a research study to follow-up on the outbreak of Equine Herpesvirus 1 (EHV1) that occurred in Western Canada following the National Cutting Horse Association event in Ogden, Utah in April - May 2011. The goal of this research is to identify factors associated with the outbreak in order to prevent and control outbreaks in the future.

The study consists of 2 questionnaires to be completed by owners/trainers of horses that attended the Ogden event (primary exposed horses) and owners/trainers that did not attend the Ogden show but had horses that were affected with EHV1 in the period following this event. These secondary exposed horses may have attended shows until the end of May 2011.

Participation in the study is voluntary and all personal information will be kept strictly confidential. If you are willing to participate in the study and have not yet been contacted directly by a member of the research team please contact Dr. Michel Levy by phone at 403-210-7476 or by email mlevy@ucalgary.ca . Feel free to share this information with your veterinarian and/or fellow horse owners.
