If your horses vaccinations have lapsed this is a great opportunity for you to restart them for a discounted price. Call us to book your visit.

BOTEquine flu is an infectious disease affecting the upper respiratory tract of horses. It is prevalent in the UK with frequent outbreaks recorded over the last few years.1

A horse with flu needs complete rest and isolation, often putting them out of action for weeks. Crucially, outbreaks can affect competitions of all levels potentially resulting in the cancellation of events in order to control the spread of disease.

Clinical signs usually appear within 1–5 days of exposure and can last for 3–6 weeks. They can include a high temperature, cough, nasal discharge, enlarged glands under the lower jaw, conjunctivitis, depression, loss of appetite and filling of the lower limbs.

If your horse shows any of these clinical signs consult the practice immediately, even if they have been vaccinated. This will allow appropriate tests to be carried out to determine the cause, and ensure that a suitable treatment plan is put in place. Remember to keep the horse isolated from others during this time as flu is highly infectious.

Snotty noseThe equine flu virus evolves and changes constantly and it is important that its development is monitored in order to ensure vaccines protect against the circulating strains. Recent outbreaks in the UK are known to be of a strain called Florida Clade 2 (a sublineage of H3N8).1 Current guidelines from the World Organisation for Animal Health (OIE) recommend that vaccines should contain both Clade 1 and Clade 2 strains of the Florida sublineage.2

Milbourn Equine will be able to provide guidance on vaccines and the correct vaccination schedule for your horse.

Diagnosis and surveillance of equine flu

The Horserace Betting Levy Board (HBLB) Equine Influenza Surveillance Programme at the Animal Health Trust (AHT) provides a laboratory testing service to all vets allowing them to submit swabs taken from horses with suspected flu and confirm not only if flu is present but also which strain is responsible.

How do we stay on top of flu?


Hygiene & Biosecurity

Maintaining good hygiene and biosecurity practices on your yard can also help to prevent the spread of equine flu. This includes isolating new horses, disinfecting vehicles, and ensuring horses have their own haynets, feed bowls and tack etc.
