Less than a week into the EHV outbreak, the Oregon State University College of Veterinary Medicine organized an information seminar for horse owners about Equine Herpes Virus and biosecurity for horse farms. John W. Schlipf Jr., DVM, MS, DACVIM-LA, Assistant Professor of Large Animal Internal Medicine at the college led the seminar, which covered 1) transmission; 2) the clinical disease and diagnosis; 3) treatment considerations; and 4) control and prevention strategies.

The seminar was planned and held just 24 hours after the first case in Oregon was announced. The State and the Vet School worked together to bring information to the horse-owning public in the state.

A few days later, videos of the seminar were edited, titles added, and the files began to be uploaded on YouTube. And a few days after that. they can be viewed directly on this blog page. The entire seminar will take less than an hour, if you want to watch it all at once, or you can come back and watch it in segments.

I just hope you will listen to this information, even if you don’t live anywhere near the states with sick horses. This disease can–and does–pop up anywhere, at any time, in anyone’s horse.

Here is most recent report from Oregon’s Department of Agriculture: (updated) As of 12:00 PM on May 26, Oregon has four horses that have tested positive but are not showing clinical signs of the neurological herpes virus (equine herpesvirus myeloencephalopathy) or EHM.? ?A fifth horse developed neurological signs and was euthanized.? It tested positive for EHM.?

All test positive horses are in Clackamas, Deschutes and Umatilla counties. ?All new cases have occurred in horse facilities that already held test positive horses. ?

All test positive horses are directly linked to the cutting horse event held in Utah from April 30 through May 8, 2011. ?The 19 Oregon horses that attended the Ogden cutting horse show all remain under quarantine with their stablemates at this time.
