Info

The Surveillance of Equine Strangles (SES) network is a Horse Trust funded surveillance project based at the Royal Veterinary College. The SES Laboratory network is comprised of ten diagnostic laboratories based across the UK, collating data from UK laboratory diagnoses of strangles.

Strangles diagnoses definition

For the purposes of the analysis depicted in this website a Strangles diagnosis refers to an individual horse that has laboratory result(s) confirming Strangles. Where multiple samples from the same horse, either taken on the same date (different sample types) or on consecutive dates within a three-month period, were confirmed as positive for S. equi, this counted as a single diagnosis. While every effort is made to consolidate data accurately, laboratory based surveillance is reliant on information supplied on submission forms and this information can sometimes be incomplete.

Clinical signs reported - alone and in combination

Evaluating this graphic

  • This graph shows the clinical signs that have been reported for Strangles diagnoses

  • Clinical signs are collated from all sampling events that each diagnosis is associated with (see home screen)

  • The graph at the left shows the 5 clinical signs that are most frequently associated with diagnoses

  • The graph on top shows the clinical signs that are reported together most often, with the linked dots below the graph indicating the associated combination

  • Note that when one clinical sign is indicated in the top graph alone (i.e. no linking lines) this means that this clinical sign was reported alone and not in combination with any others for the diagnoses made

  • For mobile users this graph is best viewed in landscape orientation
