Equine Influenza update: EIDS case reports and advice
The Equine Infectious Diseases Surveillance (EIDS) team has  a recent rise in the number of reported cases of equine influenza in the non-thoroughbred herd, including in vaccinated horses.
This is a situation we are monitoring closely. The BHA has not been alerted to any confirmed cases or clinical signs within licensed training yards, but we advise extra vigilance around biosecurity to ensure the best possible protection for horses in your care.
Please also be alert to the signs of infection, which may include a raised temperature, a harsh cough or nasal discharge. Any of these signs should be investigated promptly by a vet.
Equine influenza is highly contagious and can be airborne over reasonable distances, as well as transmitted indirectly including via people.
We therefore recommend exercising appropriate caution around the movement of both horses and people to and from your yard to minimise any risk of infection.
Any new horses entering your yard should be isolated for a period of 14 days, and again, any showing signs of EI should be promptly assessed.
A reminder that all horses running in Britain must be vaccinated in line with the , with booster vaccinations administered at intervals of not more than six months apart.
We will continue to keep trainers updated on this situation. For any questions or concerns, please contact [email protected].
