Can horses recover from EHV?
In most cases, horses will make a good recovery from respiratory disease, but the prognosis for those with the neurological disease can be very variable. If EHV is suspected, your vet will take a nasopharyngeal swab and potentially a blood sample from your horse.
How do horses get EHV?
Equine herpes virus (EHV-1 and EHV-4) is spread via nose to nose contact, contaminated equipment (water and feed buckets, tack and grooming supplies, and shoes) and respiratory secretions within stalls/stables.
Is equine herpesvirus notifiable?
A Defra spokesman confirmed it has “no plans” to change the status of EHV. “It presents no danger to human health, has no impact on international trade and there is no international obligation to control it,” she said.
How long does it take for a horse to get over a virus?
Generally horses require at least 30 days complete rest after infection, or longer if they suffer a fever for more than 4 days. Like people with influenza, individual horses recover at different rates.
What does EHV look like in horses?
The signs of neurologic EHV-1 infection range from mild hind limb ataxia (lack of coordination) to urine dribbling and inability to void the bladder properly, loss of sensation around the tailhead and thighs, weakness in the hind limbs severe enough to cause difficulty in rising, and weakness severe enough that the …
What causes equine herpesvirus?
Herpesvirus is primarily spread by direct horse-to-horse contact via transfer of respiratory secretions (e.g., nasal discharge). It is not known how far aerosolized virus can spread, although 30 yards is typically considered the maximal distance EHV-infected droplets can travel after a cough or sneeze.
Is equine herpesvirus 5 contagious?
How does EHV spread? EHV-1 is contagious and spread by direct horse-to-horse contact via the respiratory tract through nasal secretions.

What kind of herpesvirus does a horse have?
What is Equine Herpesvirus (EHV)? Equine Herpesvirus (EHV), also known as Equine Rhinopneumonitis, is a highly infectious Alphaherpesviridae found virtually worldwide. There are currently 9 known EHVs. EHV-1, EHV-3 and EHV-4 pose the highest disease risk in the U.S. horse population.
Can a horse be infected with the EHV virus?
Almost all horses have been infected with the viruses and have most of the times no serious side effects. It is currently unknown what causes some infected horses to develop the serious neurological forms associated with EHV1 that may be fatal. 2. EHV stands for equine herpes virus.
How long is the incubation period for EHV-1?
In recent years there has been an increase in the number of EHV-1 neurologic cases, also referred to as Equine Herpes Myeloencephalopathy (EHM). The virus incubation period is highly variable and can be as long as 14 days. Prognosis is good for horses not affected with the neurologic form and varies for those with neurologic signs.
How often should you test a horse for EHV?
Check temperatures of all horses on the farm twice daily (fever spikes can be missed if you check once daily) and keep a log of these recordings. If fevers are detected, then test for EHV-1. The value of starting healthy horses on an anti-viral treatment when there is no evidence of disease on the farm is questionable.
