Everywhere you turn today, someone is asking you about equine herpesvirus. From the neurologic outbreak in Europe to multiple stand-alone and multi-horse occurrences of neurologic, respiratory or abortogenic disease in North America, equine herpesvirus is a hot topic.
In Episode 53 of the Disease Du Jour podcast, we talk to Gisela Soboll Hussey, DVM, MS, PhD, an associate professor in Pathobiology and Diagnostic Investigation at the Michigan State University College of Veterinary Medicine. Dr. Hussey’s research focus is on herpesviral diseases.

EquiManagement’s Disease Du Jour podcast is focused on equine research and current best practices. Disease Du Jour is brought to you in 2021 by Merck Animal Health.
Topics Discussed:
- Are we just better at recognizing and testing, or are we actually seeing a global upswing in disease?
-
Most of those cases have been EHV-1, but a few reports are of EHV-4 infections. How do veterinarians explain the difference to horse owners?
-
Should veterinarians have a different level of concern depending on whether EHV-1 or EHV-4 is diagnosed?
-
Why do some horses develop neurologic signs with equine herpesvirus infection and others don’t?What best explains why no manufacturer has an anti-neurologic disease vaccine for equine herpesvirus?
-
How can veterinarians help protect their patients from disease caused by equine herpesvirus?There are a couple of different types of equine herpesvirus vaccines available for horses currently. What is the difference between the those vaccines given to pregnant mares to prevent abortion (such as Prodigy) and the equine herpesvirus vaccines commonly given to non-pregnant horses?
-
We know equine herpesvirus vaccination doesn’t afford complete protection—vaccinated horses CAN still get infected with equine herpesvirus. What are the benefits of vaccinating horses against EHV and how to veterinarians explain those benefits to their clients?
-

-
What best explains why no manufacturer has an anti-neurologic disease vaccine for equine herpesvirus?
-
What are your thoughts about the suggestion that vaccinated horses might be at higher risk for neurologic disease?
-
Dr. Soboll Hussey, you’ve done some research recently looking at a modified-live equine influenza vaccine (FluAvert) and how it might protect a horse against equine herpesvirus infection. Can you tell us a little bit about that?What are your thoughts about the suggestion that vaccinated horses might be at higher risk for neurologic disease?
