Clinical Signs

Diagnosis and Treatment

The virus is spread into the air by infected horses when they cough.

If flu is suspected, the vet will take nasal swabs and blood samples. You should immediately isolate and rest the horse for at least 6 weeks.

The Jockey Club insist all horses are vaccinated at least annually against equine flu. Horses competing under FEI rules require 6 monthly vaccinations.

British Riding Clubs require the horse to be vaccinated under Jockey Club rules.
