Here is info on the current outbreak of Equine Herpesvirus that has been spread throughout the western states by horses that were exposed at an Ogden, Utah cutting horse championship. Horses that left that event may have been exposed and would now be showing symptoms and possibly spreading the virus to other horses on their home ranches. This is a highly contagious disease, that can not be spread TO humans, but is easily spread BY humans to other horses.
It is important to note that this particular strain of EHV-1 is NOT protected against by the common EHV-1 vaccinations available to people in typical 3- 4- and 5-way vaccinations! This is a neurological form that has severe symptoms beyond the common “flu” version of the virus! Once the disease has become very evident, it is often beyond much in the way of successful treatment–several horses have already been euthanized. If you think your horse may have been exposed, the best way to catch the virus early is to track the horse’s temperature 2 or 3 times daily: anything above 102 degrees is a red flag! Contact your vet immediately! Other symptoms include lethargy, loss of appetite, and incoordination.
Here are some helpful sites with accurate information about the current outbreak:

Our recommendation has now changed to vaccinate for Flu-Rhino if not done within three months and everyone keep their horses home for the next 2 to 3 weeks while this simmers down.
