Equine Herpesvirus- Respiratory
Pennsylvania, United States
Alert ID: 127
December 24, 2015
There is a confirmed case of the neuropathogenic variant of EHV-1 (we received the results the night of December 23rd ) in a private, pleasure horse riding stable in Doylestown, PA (extreme Southeastern PA near Philadelphia). Thus far, three horses have been euthanized with clinical signs of EHM. There are two additional horses in the same facility that are febrile without neurologic signs to this point. One of the three euthanized horses had been shown at an event in New Jersey on December 12, 2015. Trace activity is underway. A Pennsylvania Department of Agriculture quarantine was imposed at the boarding stable in Doylestown on December 22nd. The Department is working closely with all equine stakeholders and reminding everyone of the importance of strict biosecurity applications in the control of this disease. The department is responding to this situation consistent with our science based EHV-1 response protocol. Minimum quarantine period is 21 days from the last significant clinical finding (e.g. fever) as well as the use of pcr testing for EHV-1 when appropriate. www.agriculture.state.pa.us
