Over 30 horses seemed to be in-contact with the affected horse (stabled in the same stabling area since 22 March) have been blocked in the FEI Database as a safety precaution. This includes any horses that may have already left the venue.

The Persons Responsible (PRs) have all been notified, alongside their respective National Federations and National Head Veterinarians (NHVs).

All blocked horses have been isolated and will be prevented from attending any FEI events until they have fulfilled certain health requirements which are imposed in order to minimise any potential transmission of the virus, both to their own horses and the wider horse population. The mandatory biosecurity measures include isolation for a minimum of 21 days, taking twice daily rectal temperatures and conducting laboratory testing for EHV-1. Release from isolation can only take place on the advice of a veterinarian and in order to be “un-blocked” and have access to FEI Events, the horses will need to comply with all the return to competition protocols and have the restriction lifted by the FEI Veterinary Department.
