Is there a vaccine for EHV-1?

Herpesvirus Vaccines Vaccines available against EHV-1 and EHV-4 infection are available and are being progressively more widely used. They do not completely prevent individual horses from infection but they reduce the risk of infection to other horses and the severity of clinical signs if infection occurs.

What is the difference between EHV-1 and EHM?

EHV-1: Can cause four manifestations of disease in horses, including a neurologi- cal form, respiratory disease, abortion, and neonatal death. EHM is most often due to mutant or neuropathogenic strains of EHV-1, so called because of a particular mutation in the genome.

How long does EHV last on surfaces?

Because EHV-1 can spread through contact with surfaces harboring the virus, you must know how long the germ stays viable on surfaces. Surfaces can keep the virus alive up to seven days in normal conditions and up to a month in ideal settings.

What type of virus is EHV-1?

EHV-1 stands for equine herpesvirus-1, a common pathogenof the upper portion of the respiratory tract in horses. It is common enough that you almost certainly have immunized your horse against it each time you vaccinate against rhinopneumonitis.

What is the difference between EHV-1 and EHV-4?

Equine herpesviruses are very common DNA viruses in horse populations worldwide. The two most significant are EHV-1, which causes respiratory disease, abortion, and neurologic disease; and EHV-4, which primarily causes respiratory disease and only occasionally can cause abortion or neurologic disease.

When do you vaccinate for EHV?

Primary course: A single dose should be administered from 5 months of age followed by a second injection after an interval of 4 to 6 weeks.

Is EHV-1 the same as Strangles?

The most common causes in the horse include equine influenza virus (EIV), equine herpesvirus (EHV) – also known as rhino – and Streptococcus equi subspecies equi (S. equi) – better known as strangles.

Is EHV-1 contagious to humans?

EHV-1 is not transmissible to humans. How is the virus shed from an infected horse? Horses infected with EHV-1 shed the virus in their nasal secretions.

What is the incubation period for EHV-1?

The EHV-1 incubation period is defined as the period of time from exposure of the horse to the virus, to the time the horse displays clinical signs of disease. The incubation period for EHM is typically from 2-10 days, but may be as short as 24 hours or as long as 14 days.

Is there a vaccine for EHV-4?

Vaccine. Vaccinating your horse can help prevent both respiratory disease and abortion caused by EHV-1 and/or EHV-4. There is no vaccine registered to prevent EHV-1 neurological disease.
