how to prevent and treat equine ehv  in horses


Equine Herpesvirus type 1 is a viral infection that can lead to serious neurological and respiratory problems in horses. Although the virus can easily be transmitted from horse to horse via direct contact, saliva and nasal secretions it is extremely contagious. There are many ways to prevent and treat EHV-1.

Understanding EHV-1

EHV-1, a highly contagious virus, can be spread from horse to horses through contact, saliva and nasal secretions. EHV-1 can also spread to other animals through contact with contaminated items, such as bedding, grooming supplies, and tack. Horses can contract the virus through respiratory or neurological diseases, and it can also cause abortion in pregnant mares. Horses with immunocompromised, stressed or other unhealthy conditions are more likely to develop serious symptoms.

EHV-1 Prevention

Good biosecurity is the best way to prevent EHV-1. This includes:

  • Every year, vaccinate your horse against EHV-1.
  • Before introducing new horses, it is important to isolate them from the herd for at most two weeks.
  • Avoid contact with other horses on trails and at shows.
  • Avoid sharing grooming supplies, tack, feed, water, or other items.
  • Cleaning and disinfecting barns, stalls, and trailers is a must.
  • Monitor horses for signs and symptoms of illness, and immediately isolate any horses showing signs.

Quarantine Horses

It is essential to quarantine a horse when you introduce a horse to your herd. You can observe your horse and test for EHV-1, as well as any signs of illness. The horse should be kept from other horses during this time and should avoid any contact with them.

Vaccinate Horses

EHV-1 vaccinations are one of the best ways to stop the spread of the disease. There are vaccines that protect against the neurological and respiratory forms of the virus. Your veterinarian will help you decide which vaccine is right for your horse.

EHV-1 is treated

It is crucial to notify your veterinarian immediately if a horse has been diagnosed with EHV-1. EHV-1 treatment is usually supportive. It may include antibiotics, anti-inflammatory drugs, fluids, vitamins, or electrolytes. Sometimes, antiviral medications may also be recommended.

Horses with Quarantine Injured

EHV-1-infected horses should be kept away from the rest until they are fully recovered. This prevents the virus from spreading to other horses.

Manage Stress

EHV-1 treatment for horses requires that you manage stress. Stressed horses are more likely than others to get ill, and to experience more severe symptoms. Horses need to be kept in a calm environment with lots of exercise and rest.
