As you may be aware, there has been an outbreak of Equine Herpesvirus at a competition centre in Hampshire. So far all reported cases have been on the premises, but unfortunately four horses have had to be euthanised due to the severity of their disease.
How is EHV spread?
EHV is spread via the respiratory tract: through the air and by direct contact.
What is EHV?
There are three types of Equine Herpesvirus:
– EHV 1: This causes respiratory disease and occasionally neurological disease and abortion
– EHV 3: Less frequently seen but can cause venereal disease in stallions and mares
– EHV 4: This causes respiratory disease that is generally mild
What are the symptoms?
– Respiratory disease: snotty nose, cough, fever, reduced appetite, poor performance
– Neurological disease: from mild muscle weakness and incontinence (bladder paralysis) to collapse and paralysis
– Abortion: still-birth, abortion, weak or sick foals
Can I still compete?
Competition centres are publishing their own advice as to whether they are open or not, but most centres outside of the Hampshire area appear to be running as normal UNLESS your horse is suspected to have travelled to a high-risk area or has any suspect symptoms, in which case you are encouraged not to go. It is best practice to carry out good hygiene at showgrounds i.e. bring your supply of water, do not share equipment, avoid nose-to-nose contact with other horses e.t.c.
What should I do if my horse has travelled to a high-risk area?
If your horse has recently travelled to the Hampshire area (including up to two weeks before the outbreak was announced) or you suspect your horse has come in contact with the disease, please contact your vet, who will be able to give you specific advice. Your horse should be isolated from the others on the yard and you should avoid contact with other horses, awaiting further veterinary advice.
Should I be vaccinating for herpes now?
Vaccination can help reduce the likelihood of infection and the severity/duration of disease, although it is not licensed for the neurological form. Vaccination for horses other than broodmares consists of a primary course of two vaccinations, 4 weeks apart, followed by 6 monthly booster vaccinations. Pregnant broodmares should receive vaccinations in their 5th, 7th and 9th month of pregnancy, and that horses who come in contact with broodmares are also vaccinated.
However, if your horse is suspected to have come in contact with horses affected by this recent outbreak then we do not recommend immediate vaccination. In this instance please contact us for further advice.
If you are concerned that your horse has been exposed, have any questions, or if you’d like to book in a vaccination, please give the surgery a ring on 01608730085.
