From all of the western states reporting, 23 confirmed, 24 suspects, and 4 dead or euthanized. NO confirmed cases in Utah.
One other fact. In outbreaks of this same disease in the past, in other parts of the country, there was a pattern that emerged. Those horses that were vaccinated most frequently for "flu-rhino" had the highest incidence of the neurological form of EHV-1. The reason is that immune complexes which are formed when vaccinating, are involved in the nerve damage with this disease. Therefore, DO NOT vaccinate your horses beyond what is normally recommended.
