What Virus Kills Horses?
Equine herpesvirus myeloencephalopathy (EHM) is another name for the neurologic disease associated with equine herpesvirus (EHV) infections. EHV-1: Can cause four manifestations of disease in horses, including neurological form, respiratory disease, abortion and neonatal death.
What virus diseases affect horses?
- Common Equine Diseases.
- Equine Influenza (“Flu”)
- Rhinopneumonitis/Equine Herpesvirus (EHV)
- Equine Encephalomyelitis (“Sleeping Sickness”)
- Equine Infectious Anemia Virus (EIA)
- West Nile Virus.
- Streptococcus equi (“Strangles”)

What is the deadliest disease in horses?
Equine Encephalomyelitis (Sleeping Sickness): Encephalomyelitis is caused by a virus, which is transmitted by mosquitos. The virus causes inflammation of the brain and spinal cord and is often fatal. Stricken horses may lose their appetite, display excitable or compulsive behavior and walk blindly into objects.
What is the most common virus in horses?
Equine influenza is one of the most common infectious diseases of the respiratory tract in horses. This is a highly contagious virus that can be contracted through direct contact with an infected horse or indirectly via a contaminated environment.
How do horses get EHV?
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.
What is the number one killer of horses?
The number one killer of horses is colic. Colic is not a disease, but rather a combination of signs that alert us to abdominal pain in the horse. Colic can range from mild to severe, but it should never be ignored.
Can a horse recover from EHV?
In most cases, horses exposed to EHV-1 will develop a fever and possibly nasal discharge and then go on to recover. However, the neurologic EHM strain has a high mortality rate of 30-50%. Recovery time can vary from several days to more than a year.
What causes sudden death in horses?
One of the major causes of sudden death in is cardiac arrest. But what are the reasons behind this cardiac arrest? Normally viral and bacterial infections, drugs, various diseases, tumors, electric shock etc. can lead to heart failure in horses.
What is the second leading cause of death in horses?
The second leading cause of death in horses in the United States is a condition called laminitis. (Colic is the leading cause.)
Which 3 parasites cause the most damage to the horse?
Probably the most important, in terms of health risk, are the first three: small strongyles, roundworms, and tapeworms. The lifecycle of most internal parasites involves eggs, larvae (immature worms), and adults (mature worms). Eggs or larvae are deposited onto the ground in the manure of an infected horse.
How long does equine herpesvirus last?
Horses infected with EHV-1 shed the virus in their nasal secretions. Respiratory shedding of the virus generally occurs for 7-10 days, but may persist longer in infected horses. Horses that have been exposed to the virus, but are not showing clinical signs of disease can shed virus.
Common causes of viral respiratory tract infections in horses include: equine influenza (EIV), equine herpes (EHV-1 and -4), and Equine Rhinitis (ERAV).
What does strangles do to a horse?
Strangles is a highly contagious infection that causes fever, nasal discharge and abscesses near swollen lymph nodes. Hot packs can help the abscesses mature before opening and flushing them out. Horses that struggle to breathe may need antibiotics or hospital care.
What disinfectant kills EHV-1?
Clean your equipment. You can readily kill EHV-1 with many common disinfectants including diluted bleach, quaternary ammonium compounds, accelerated peroxide and peroxygen compounds, and iodophors.
Is EHV contagious to humans?
Equine Herpes Virus-1 (EHV-1) is a virus that is ubiquitous in the environment and found in most horses all over the world. All equids are suscepti- ble to EHV-1. The virus is not transmissible to humans.
What are the signs of equine herpesvirus?
Clinical signs of EHV-1 and EHV-4 respiratory disease are very similar to equine flu and can include:
- High temperature, above 38.5°C.
- Nasal discharge.
- A dry cough.
- Loss of appetite.
- Reduced performance.
- Lethargy/depression.
What kills horses quickly?
Rapid and Unexpected Death in Horses Part A – Toxins
- Introduction.
- Botulism.
- Ionophore Toxicity.
- Yew Poisoning.
- Poison Hemlock.
- Red Maple Leaf Poisoning.
- Oleander Toxicosis.
- Cantharidiasis (Blister Beetle Poisoning)
How long does strangles last in a horse?
Most horses recover from strangles in 3-4 weeks. It’s extremely important not to remove horses from isolation just because their symptoms have gone. Strangles bacteria can spread for around six weeks after signs of infection have gone, sometimes longer.
What kills a horse in the wild?
Mountain lions are natural predators of wild horses and burros. These apex predators balance ecosystems and could help to regulate wild horse populations. But between hunting tags and government kill programs aimed at protecting livestock, thousands of mountain lions are killed on public lands each year.
Can you vaccinate against EHV?
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.
How do I protect my horse from EHV-1?
Don’t pet or interact with other horses, and don’t lend out your grooming implements or feed and water tubs. Wash and disinfect your trailer after shows and, if you transport horses commercially via land or air, ask whether the vehicles or boxes are disinfected with antiviral agents between shipments.
