Notes: Update 5/20/20: The Alcohol and Gaming Commission of Ontario (AGCO) continues to monitor cases of the neuropathic strain of EHV-1 present at Woodbine Racetrack. On May 17, the AGCO reported two thoroughbred horses that resided in Barn 12 at Woodbine had tested positive for the disease, and ordered a number of measures be put in place to address the situation. All 59 horses residing in Barn 12 have since been tested and in total, 20 cases of EHV-1 have now been confirmed among those horses. The affected horses are in isolation or have been sent to the Ontario Veterinary College for treatment. Regrettably one horse has had to be euthanized due to neurological disease. The horses in Barn 12 that tested negative will be retested on May 19. All horses in neighboring Barn 11 are also being tested. To further trace possible contact with the infected animals, Woodbine is identifying all horses and people that may have come into contact with or been in proximity to horses in Barn 12. The AGCO has also ordered Barns 33 and 35 be locked down due to a horse showing signs of fever. The horse has been isolated and will also be tested on May 19.

Number Exposed: 5;
Age: 2;  Breed: Thoroughbred (TB); Clinical Signs: Neurological Signs; Confirmation Date: 5/16/2020; 
Notes: The Alcohol and Gaming Commission of Ontario (AGCO) has confirmed that two horses residing at Woodbine Racetrack have tested positive for the neurotropic strain of EHV-1. Both horses are 2-year-old thoroughbred horses that resided in Barn 12 at Woodbine. The horses were transported from Woodbine to the Ontario Veterinary College for testing and treatment on Saturday May 16, 2020 after showing neurological symptoms, along with a third horse that subsequently tested negative. The AGCO received the results late on Saturday May 16, 2020. The AGCO has directed that four additional horses residing in Barn 12 at Woodbine be isolated as a precaution. One of the four horses has been isolated because it resided near the two positive horses. The three other horses have fever symptoms but have otherwise not shown signs consistent with EHV-1. The following measures are now in effect: -In order to determine whether the disease has spread to horses in other barns, no horses are to exit Woodbine Racetrack without AGCO approval until further notice. This restriction will be reviewed on an ongoing basis. -No horse is allowed in or out of Barn 12 until further notice, including for training, except for emergency veterinary treatment or to be isolated. This restriction will be reviewed, based on the progression of the disease. -Only essential people shall enter Barn 12. -All horses stabled at Woodbine must have their temperatures taken and recorded visibly on the horse’s stall door for twice daily inspection. Trainers with horses that have clinical signs consistent with EHV-1 infection (including fever of 101.5 F/38.5 C or higher) or respiratory signs (cough, nasal discharge, and/or neurological signs) must immediately report these findings to their veterinarian. -Equine dentistry is not permitted, except for emergencies. -Only ponies housed in the same barn will be allowed to pony horses. Horse people who had horses at Woodbine Racetrack within the last seven days should monitor their horses for any signs of illness.  For more information go to:  https://www.agco.ca/blog/horse-racing/may-2020/industry-notice-confirmed-cases-ehv-1-woodbine-racetrack-monitoring-and
