July 1, 2015-Dr. Wright from Kingman has notified the SVO that she has confirmed Equine Influenza Virus (EIV) in a local horse. The client was recently at a barrel race in Boulder City, NV. Approximately 4 days after returning home, a horse became ill with upper respiratory signs and fever. Samples were PCR positive for EIV. Currently 6 of 10 horses have clinical signs. It was also reported there had been no vaccination unless greater than a year earlier. Hopefully practitioners can use this information to help persuade folks of the value of vaccines used strategically.
