Diagnostic tests done at the University of California, Davis, have confirmed that a euthanized horse stabled at Santa Anita Park, in Arcadia, California, was positive for equine herpesvirus type-1.
On March 5, My Sugar Sugar, an unraced 3-year-old Thoroughbred filly trained by Eddie Truman, required euthanasia after developing neurologic signs. There have been no other reported cases of EHV-1 at Santa Anita.
According to a statement from the California Horse Racing Board, My Sugar Sugar had been feverish four days earlier and developed neurologic signs on day four. Biosecurity procedures were implemented that day and the California Department of Agriculture was notified of a suspected case of EHV-1.
The average incubation period for EHV-1 is four to seven days, with the majority of cases being three to eight days, but with some taking up to 14 days. All horses in the stable are being closely monitored and none of the others has exhibited signs of fever or illness.

The Illinois Bureau of Animal Health and Welfare has received laboratory confirmation of an EHV-1 infection in a private boarding stable in Lake County in Illinois. Several horses in the stable are currently exhibiting neurologic signs consistent with those exhibited in EHV-1 infected horses. The horses stabled in the facility have been placed under quarantine by the Bureau of Animal Health and Welfare. This quarantine will remain in place until such time as it is determined that exposure to these horses no longer poses a risk to other horses.

From the Utah Department of Agriculture and Food (March 5, 2013)
The Utah state veterinarian has confirmed seven cases of EHV-1 in Utah, all of which are confined to locations in Cache County. The state veterinarian's office is restricting the movement of the infected animals as a precaution to prevent the spread of the disease. The outbreak remains confined to Cache County, as there have been no other reports of EHV-1 symptoms in horses in other areas of the state. Nonetheless, horse owners throughout Utah are advised to take extra biosecurity precautions when taking their animals to shows or public arenas.
Two of the horses have been humanely euthanized because of their condition. The remaining animals are being treated, and are under veterinary care. The Cache County Fairgrounds Horse Arena has closed its riding arena until further notice because all of the horses had been at the facility recently. Horse owners who have taken their animals to the Cache County Fairgrounds Arena during the past 30 days should monitor their horse's temperature and report concerns to their local veterinarian.
The state veterinarian recommends that horse facilities proceed with planned equine events, and that horse owners planning on traveling to an event should take their horse's temperature daily, beginning three days prior to travel and daily during the event. Horses with temperatures of 103 and above should not travel or mingle with other horses. Horses should be isolated for two weeks after returning home from an event, during which time they should be monitored for disease symptoms.

One mare is dead and two horses are showing neurologic signs in an outbreak of the neurologic form of EHV-1 in Quebec that has left more than 50 horses in quarantine.
A 12-year-old Quarter Horse mare showed signs of illness last week, including fever, lethargy, and difficulty standing and walking, according to treating veterinarian Dr. Isabelle Morin of the Clinique Vétérinaire Sagamie in Alma, Quebec. The horse then "rapidly deteriorated" over the next 24 hours and was unable to stand. She was humanely euthanized.
Necropsy results confirmed the presence of neurologic EHV-1, Morin said. All 53 remaining horses at the Bédard Quarter Horse riding stable in Chicoutimi, Quebec, were immediately placed in quarantine by their veterinarians and their owner.
