A virus that brings complications and isolation, an infection that causes the cancellation of events, does that remind you of anything? We are not talking about covid 19 which occupies a large part of national and international news but about another respiratory virus which can seriously affect horses. There are several cases identified in Belgium.
“The equestrian world is affected by a virus”, wrote, via Alert Us, Steve who works in a stable. The editorial staff received several messages reporting an epidemic of rhinopneumonia affecting horses. Valérie believes “that it is important to warn the population so that our dear fellow citizens do not touch our horses during their ride and do not transmit the virus to other equines”. The rider says she is worried “because it is a very contagious strain which can be transmitted by contact”.
Outbreaks of equine herpes virus type 1 (EHV1) have been identified in recent weeks in Belgium and abroad. The virus began to spread last month during a competition in Valencia, Spain, in which Belgian horses took part.
Four dead horses in Spain
According to Michel Devos of the veterinary commission of the Wallonia-Brussels Equestrian League, there are 8 to 10 positive cases identified in our country (cases confirmed by a test, so there could potentially be more). The specialist is not aware of any death linked to this disease in our country but four horses died in Spain.
Also known as rhinopneumonia, it is a respiratory tract virus that only infects equines. There is no danger for humans. Unfortunately, this infection is very contagious and it can have serious consequences for horses.
The disease is spread by inhalation or contact with infected secretions. It can therefore be transmitted by humans (by transporting the virus, for example by touching animals) or by equipment.
This virus, which presents itself every year, generally causes mild respiratory forms. The increase in severe cases is therefore judged “disturbing”, especially since “the arrangements that can be made are not subject to any legal obligation. We rely on the goodwill of horse owners “, indicates the veterinarian.
The first symptom to watch out for is fever: “Above 38.5 °, one is wary and from 39 °, it is better to consult”, specifies Michel Devos. Then, classic respiratory symptoms, such as coughing, may appear. Neurological problems can develop, ranging from slight incoordinations of the hindquarters to severe paralysis. In pregnant mares, rhinopneumonia can lead to late abortion of the foal.
To prevent the disease, a vaccine exists. Although it does not offer a total guarantee, it is recommended and not compulsory (unlike that of influenza) to help horses develop good resistance to the virus.
Cancellation of competitions in Belgium and abroad
Following the recent serious cases of infections, the FEI (the International Riding Federation) has decided to abolish all international competitions until March 28. This measure affects 10 European countries: Belgium, France, Spain, the Netherlands, Portugal, Italy, Austria, Poland, Germany and Slovakia.
In line with the decisions of the FEI, the Royal Belgian Federation of Equestrian Sports recommends canceling training, other gatherings and in general all non-essential transport. The goal is to avoid at all costs that different “bubbles” come into contact with each other.
The greatest source of contamination is direct horse-to-horse transmission. Michel Devos therefore advises to isolate the horses and not to welcome new arrivals in the stables. “If there is any doubt, take the temperature morning and evening. We must isolate the patients and consult a veterinarian”.
