New case of neuropathogenic strain of EHV-1
CDFA has confirmed a total of nine cases of EVH-1 in Orange County, CA.
On January 18, 2012, one of the positive horses which initially displayed a fever and limb edema became recumbent and the decision was made to euthanize this horse. Necropsy results as to the cause of the recumbency are pending. The facility remains under quarantine and all exposed horses are being monitored.
The source of the outbreak has not been identified. The initial epidemiologic investigation reveals no link to the three 2011 California neuropathogenic EHV-1 incidents.
