The SES Laboratory network is comprised of multiple 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.
