We see a few cases each year, though some years are worse than others!
DID YOU KNOW?
Strangles was one of the first equine diseases to be described by the early writers of veterinary science (was first reported in 1215) and is one of the most commonly diagnosed contagious diseases of the horse, worldwide. Though strangles is highly contagious and can affect many horses on a farm, particularly young animals, most horses with infection recover without complication.
It is not uncommon for strangles infections to recur on a farm with previous outbreaks of the disease. The bacteria can survive in water sources for over a month, but the primary source of recurrent infections is most likely asymptomatic carrier horses. Anywhere from 4-50% of the horses on farms with recurring strangles are asymptomatic carriers of the infection, and they may continue to shed the bacteria for months to even years, serving as a continual source of new infections.
If you suspect a strangles outbreak, be sure to involve your veterinarian right away to determine the diagnosis and the best control practices for your particular farm. Strangles is a reportable disease in some states. Movement of any horses on or off the farm should be stopped, and new horses should not be introduced. Monitoring the temperature of all horses daily and isolating horses at the first sign of fever is one of the most effective ways to stop the spread of infection. Infected horses can transmit the bacteria to healthy horses one to two days after they develop a fever.
