Fear and uncertainty have spread through the equestrian world following an outbreak of Equine Herpesvirus (EHV) that started at a competition in Valencia, Spain. Several horses were infected with this dangerous strain of the virus, resulting in fatalities and new outbreaks in other countries.
How does this EHV behave?
The genetic variant of EHV responsible for this outbreak is considered highly contagious and difficult to treat, as it affects the horse's neurological system. This outbreak has already been described as “probably the worst in Europe in many decades” by Sabrina Ibanez (Secretary General of the FEI).
How is this EHV transmitted?
It is transmitted through direct contact between horses via the respiratory tract, through nasal secretions. It can also spread indirectly by contact with contaminated surfaces: people’s hands/clothing, equipment, cleaning materials, transport vehicles, food, etc. Although it is known that the virus can be transmitted through the air, it is difficult to determine how far it can spread.
How to prevent the spread of EHV?
This virus can survive for several days in the environment, so it is advisable to:
-
Clean and disinfect equipment, surfaces and shared areas;
-
Frequently wash and disinfect the hands of anyone who comes into contact with horses;
-
Keep returning horses isolated and under observation;
-
Minimise/avoid travel and gatherings of horses.
Vaccination against EHV can help reduce its spread, although it does not eliminate the risk of a vaccinated horse contracting the neurological form of the disease, so it is essential to contain its spread.
It is well known that a proper diet is key to keeping any horse healthy. Learn how to feed your horse to boost its immune system in our article.
