EHV-1 UPDATE: One Confirmed Case in Humboldt County

Humboldt County – A horse in Humboldt County has tested positive for EHV-1 and has been traced back to the March 8-10 Nevada Junior/High School Rodeo event in Fernley. The 14-year-old Quarter Horse mare first exhibited clinical signs on March 21. This horse was not exhibiting neurological signs and was clinically normal on April 1. The facility where the horse is located has a total of five horses and has been placed under quarantine. The Fallon Jr and Sr High School Rodeo scheduled for April 5-7th is postponed.

“The quarantine on this horse will expire before the Fallon rodeo event, so I have not recommended canceling it,” said Dr. JJ Goicoechea, Nevada Department of Agriculture (NDA) State Veterinarian. “However, I absolutely support their decision, and I thank them for continuing to make tough decisions in efforts to stop this outbreak.”

Two horses tested last week for EHV-1 in Clark County, NV were negative. One additional test from southern Nevada is pending. EHV-1 is a reportable disease, meaning when veterinarians diagnose it, they are required to notify the Nevada Department of Agriculture, per NRS 571.160.

“The most important thing right now is that new positive cases of EHV-1 get reported to us immediately,” Dr. Goicoechea added. “It’s a law that helps us protect against the spread of disease, and we appreciate the horse community’s continued support.”

Dr. Goicoechea continues to recommend best biosecurity practices as event season is underway, and always monitor horses for signs of disease, like fever or runny nose.
