The Pennsylvania Department of Agriculture has reported that three barns at The Meadows Racetrack remain under quarantine for having or previously having horses with equine herpesvirus myeloencephalopathy (EHM).
A total of four EHM horses have been identified, with an additional eight horses having tested positive for EHV-1 without neurologic signs in this incident.
The last EHM case was identified on February 23, 2018.
A daily monitoring period for clinical signs in the remaining exposed, asymptomatic horses is ongoing in the quarantined barns. Updates will be posted as they become available.
The Equine Disease Communication Center (EDCC) works to protect horses and the horse industry from the threat of infectious diseases in North America. The communication system is designed to seek and report real time information about disease outbreaks similar to how the Centers for Disease Control and Prevention (CDC) alerts the human population about diseases in people.
