EHV-1 Fair Grounds, Louisiana, Outbreak Update

On Tuesday, January 10, 2017, two suspect horses that had previously tested negative for EHV-1 on both nasal and blood samples retested positive for EHV1 non-neuropathogenic strain at the Louisiana Animal Disease Diagnostic Lab (LADDL). One of the horses retested negative on blood, but positive on nasal samples. The other was positive on both blood and nasal samples. 

Another new febrile horse from Barn 30 tested positive for EHV-1 non-neuropathogenic strain on both blood and nasal samples. 

All three horses have been placed into isolation and the barns are under quarantine. 

On January 12, 2017, a horse in Barn 20 spiked a temperature of 104 and test results on blood and nasal samples are reported negative and retesting protocols will be followed. 

Three barns were tested for future quarantine release on Wednesday and results are as follows: Nine (9) horses in Barn 36, 19 horses in Barn 14 and two horses in the Receiving Barn have been reported positive for EHV-1 non-neuropathogenic strain. 

To date, test results report that 38 horses tested positive for EHV1 non-neuropathogenic strain and two tested positive for EHV-1 neuropathogenic strain. Sixty-five horses that were potentially exposed to EHV-1 in a receiving barn prior to January 2 have been traced, isolated and are currently in the testing process. 

The entire premise of the Fair Grounds Racetrack was placed under quarantine with racing still allowed with barns not symptomatic or test positive. 

The Louisiana Department of Agriculture & Forestry, USDA, and Racing Commission veterinarians continue to work with track personnel in responding to the incident at the Fair Grounds.

About EDCC

The Equine Disease Communication Center 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.

The goal of the EDCC is to alert the horse industry about disease outbreak information to help mitigate and prevent the spread of disease. Ultimately frequent and accurate information about diseases outbreaks improves horse welfare and helps to prevent negative economic impact that can result from decreased horse use due to a fear of spreading infection. As part of the National Equine Health Plan the EDCC will serve as part of the communication to help educate and promote research about endemic and foreign disease.

Working in cooperation with state animal health officials and the United State Department of Agriculture, the EDCC seeks information about current disease outbreaks from news media, social media, official state reports and veterinary practitioners. Once information is confirmed, it is immediately posted on this website and messages sent to all states and horse organizations by email. Daily updates are posted until each outbreak is contained or deemed no longer a threat.

The EDCC is made possible by generous donations from organizations and horse owners. Please visit our sponsors that have generously supported this program for the benefit of the health and welfare of horses. To learn how you can help go to SUPPORT.
