Fear and uncertainty have spread across the equestrian world following an outbreak of Equine Herpes Virus (EHV) that began at a show in Valencia, Spain. Several horses have been infected with this dangerous variant of the virus, resulting in some fatalities and 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 being described as “probably the worst in Europe for 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 materials, means of transport, food, etc. Although it is known that the virus can be transmitted via the air, it is difficult to establish at what distance it can be transmitted.
How to prevent the 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 cleaning and disinfection of the hands of those who come into contact with horses;
- Keep horses that are returning home in isolation and under surveillance;
- Minimize/avoid movement and crowding of horses.
Vaccination against EVH 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 key to keeping any horse healthy. Learn how to feed your horse to strengthen its immune system in our article.
