Alert ID: 390
December 12, 2016
One of the EHV-1 confirmed positive horses developed severe neurologic symptoms on Saturday and is receiving supportive treatment. No additional confirmed cases of EHV-1 or new febrile horses have been identified at this time. This incident now has two (2) EHM cases and one EHV-1 confirmed case. All three cases have been caused with the neurotrophic strain of the EHV -1. The affected horses are part of a wintering pack string of horses and mules on an isolated, high desert ranch. These horses/mules have been placed under quarantine with no movement allowed in order to limit disease transmission. The investigation of this disease outbreak is continuing by CDFA staff. Enhanced biosecurity is in place and we appreciate the cooperation and assistance from owner and private veterinarian. Updates will continue on a 48 hour basis.
