Equine Influenza Outbreak

All meetings in Britain scheduled for Thursday have been cancelled following three confirmed cases of equine influenza, all from vaccinated horses in an active racing yard. Meetings at Huntingdon, Doncaster, Ffos Las and Chelmsford will not go ahead after the BHA announced emergency measures in a statement released late on Wednesday evening.

The statement read: "The BHA, with unanimous support of the industry veterinary committee, has taken the decision to cancel racing at all British racecourses on Thursday 7 February 2019. This is following the BHA being informed this evening by the Animal Health Trust of three confirmed Equine Influenza positives from vaccinated horses in an active racing yard. Horses from the infected yard have raced today at Ayr and Ludlow, potentially exposing a significant number of horses from yards across the country and in Ireland. The fact that the cases have been identified in vaccinated horses presents a cause for significant concern over welfare and the potential spread of the disease and the action to cancel racing has been viewed as necessary in order to restrict, as far as possible, the risk of further spread of the disease."

The statement continued: "The BHA has worked quickly to identify which yards could have potentially been exposed today and identify the further actions required. The BHA is presently communicating with yards potentially exposed to ensure appropriate quarantine and biosecurity measures are put in place and horse movements restricted to avoid possible further spread of the disease. The full extent of potential exposure is unknown and we are working quickly to understand as much as we can to assist our decision making. The BHA is working closely with the Animal Health Trust and will issue a further update tomorrow. We recommend that any trainer who has concerns about the health status of any of their horses should contact their veterinarian."

Cases of equine influenza had been reported in recent weeks, originally in France but spreading to Ireland and Britain. The BHA issued a warning to racing professionals on 19 January but, until now, no cases in Britain had been confirmed from active yards in vaccinated horses.

Equine influenza is an airborne infection and can travel over fairly large distances and even be transferred through humans, so the prospect of it spreading can be high.

Outbreaks are rare, but one such incident in Australia in 2007 brought racing to a halt nationwide on 25 August and, while the Melbourne spring carnival took place under strict bio-security measures, racing in Sydney did not resume until 1 December of that year.

As we understand it horses with the disease remain infectious for up to seven to 10 days. The dry, harsh-sounding cough may linger for several weeks so disrupting a season's work. The disease has a very short incubation period, re time from infection to symptoms, of two to six days and clinical signs usually resolve in one to three weeks. We can only hope that powers that be learn lessons of old, but somehow we doubt that will happen and apart from racing in general, fear for this year's Cheltenham Festival...

On a personal note I have prepared and worked so hard for the 2019 Cheltenham Festival and it could now amount to nothing! I was desperate to share the work with my members and believed it was my most valuable. I have shares in four horses at some cost and I had already finalised plans for Newbury on Saturday and Hereford on Monday. Damn!
