Surveillance of Equine Strangles is a new surveillance scheme being developed at the Animal Health Trust.

Our laboratory network collates data from UK diagnostic laboratories on positive diagnoses of Streptococcus equi, the causative agent of Strangles. Findings are summarised quarterly and shared below.

One of the long term aims of Surveillance of Equine Strangles (SES) is to provide information that will help vets and owners increase their awareness of Strangles outbreaks enabling them to increase their biosecurity measures, therefore keeping their horses and ponies happy, healthy and free from Strangles.
