EQUINE | ECOD Report ECOD Report September 2019 Period reviewed: January – September 2019 This report summarizes the equine disease events logged on the ECOD (Equine Cause Of Disease) passive surveillance system developed for the South African Equine Veterinary Association. Overview and User Reports Uptake of the ECOD system remains slow with the very few active contributing users. In the period reviewed 10 additional veterinarians or practices registered on the system. Excluding SAEHP users, who capture much of the laboratory based results on ECOD, there were a total of 18 active users over the nine months who captured disease events. The majority of non-SAEHP users captured events in Gauteng, KZN and the Western Cape Province. For the purposes of this report we only consider those disease events that were classified as confirmed (rather than suspect – 120 events were in this category). A total of 793 confirmed disease events, constituting 958 cases, were logged during the period. Private vets logged 8.2% of disease events for the period. Disease events generally refer to all cases on an individual holding, and for the sake of completeness have been included in the analysis below, however, case totals provide the most accurate depiction of the data reported. African horse sickness AHS reporting was one of the main reasons behind the development of the ECOD system, and the majority of 38 cases are logged by SAEHP staff from positive laboratory results for this disease. These logs are cross referenced against any logs made by private veterinarians to ensure that duplication of results/ cases is avoided. There were a substantial number of AHS cases in the period reviewed. A total of 593 cases were reported for 476 events. Provincial case totals are shown in Table 1. Figures 1 and 2 show the spatial distribution by local municipality and the epidemic curve of cases for the period reviewed.
