California authorities have confirmed a second horse has tested positive for the non-neuropathogenic strain of the equine herpesvirus (EHV-1).
A three year-old racehorse at Santa Anita became ill with a temperature of 103F and was diagnosed on Friday. The thoroughbred colt has been asymptomatic since the initial fever, according to a press release.
The colt was one of the horses exposed to the thoroughbred filly confirmed last week to have EHV-1. The filly is recovering.
The investigation done by the California Department of Food & Agriculture indicates “that the situation remains isolated to the initial set of exposed racehorses.” Officials say there is no evidence of spread beyond this population of horses.
The California Horse Racing Board and the CDFA state their organizations continue to closely monitor the situation.
