Outbreak of highly contagious horse disease spreading among thoroughbreds

An outbreak of a highly contagious horse disease is spreading among thoroughbreds in the North Island , raising concerns about exports. Strangles is a serious bacterial infection for horses, ponies and donkeys that causes a fever and painful abscesses in the throat. The disease has been confirmed on a dozen stud farms - all but one are in Waikato and the horses have been isolated to prevent it spreading further.
