Equine Herpes Virus
(EHV-1) - neurological form

We have created this dedicated hub to collect and share all the latest information and developments around the outbreak of Equine Herpes Virus (EHV-1 – neurological form), which originated in Valencia (ESP) in February 2021 and has led to the FEI cancelling international events in 11 countries on the European mainland from 1 March to 11 April 2021.

The FEI has been working with world leading epidemiologists since the early stages of the EHV-1 outbreak in mainland Europe. This group of EHV experts, which has provided science-based recommendations to the FEI throughout each phase of this outbreak, has now been formalised as the FEI Veterinary Epidemiology Working Group. Reports and recommendations from the Group will be published on a weekly basis and are available in the Reports menu above.

This strain of EHV-1 is particularly aggressive and has already caused equine fatalities and a very large number of severe clinical cases. The science provided by the epidemiologists is clear – stopping competition for four weeks initially (and now an additional two weeks) is the only way to prevent the further spread of this terrible disease.
