Fear and uncertainty have spread across the equestrian world following an outbreak of Equine Herpes Virus (HVE) that began at a show in Valencia, Spain. There have been several cases of horses infected with this dangerous variant of the virus, resulting in some fatalities and the occurrence of new outbreaks in other countries.
How does this LVH behave?
The genetic variant of LVH that caused this outbreak is considered highly contagious and difficult to treat, as it affects the horse's neurological system. This outbreak is already considered as “probably the worst in Europe in many decades” by Sabrina Ibanez (FEI Secretary General).
How is this LVH transmitted?
It is transmitted by direct contact between horses through the respiratory tract, via nasal secretions. It can also be transmitted indirectly through contact with contaminated surfaces: human hands/clothing, equipment, cleaning material, means of transport, food, etc. Although it is known that the virus can be transmitted via the air, it is difficult to establish how far it can be transmitted.
How to prevent transmission of LVH?
This virus can survive for a few days in the environment, so it is advisable to:
- Cleaning and disinfection of equipment, surfaces and common areas;
- Frequent hygiene and disinfection of the hands of those who come into contact with the horses;
- Keep horses that are returning home in isolation and under surveillance;
- Minimize/avoid displacements and agglomerations of horses.
Vaccination against LVH can help reduce its spread, although it does not exclude the risk of a vaccinated horse contracting the neurological form of the disease, so it is imperative to contain its spread.
It is well known that a proper diet is the key to keeping any horse healthy. Learn how to feed your horse to Strengthen the Immune System in our article.
