State animal health officials in California and North Carolina have lifted quarantines on three premises where  horses had tested positive for equine herpesvirus-1 (EHV-1) last month. All three quarantines were put into place in early to mid-January.

North Carolina’s first EHV-1 case was confirmed on Jan. 5 when a horse residing in Rockingham County tested positive for the neurologic form of the virus. The mare was admitted to and quarantined at North Carolina State University’s College of Veterinary Medicine, and has since recovered.

On Feb. 9 the North Carolina Department of Agriculture & Consumer Services issued a statement indicating the month-long quarantine imposed on the mare’s home facility had been lifted, as no additional horses showed any signs of the virus.

“It is a testament to our preparedness activities and the cooperation that we received from the College of Veterinary Medicine that we were able to respond so quickly to this virus,” said State Veterinarian David Marshall, DVM, in the statement. “This is a highly contagious virus, and cooperation from all parties was the key to ensuring that it didn’t spread any further.”

In California, two premises—one in Orange County and one in Riverside County—were quarantined after resident horses tested positive for EHV-1. Epidemiologic investigations on both outbreaks led the California Department of Food and Agriculture (CDFA) to conclude the two incidents were unrelated.console.log('scenario 2');
