What Does Eva Mean In Horses?
Equine viral arteritis (EVA) is an economically important, contagious, viral disease of equids caused by equine arteritis virus (EAV). Exposure to EAV may result in clinical or more frequently, asymptomatic infection, depending on the virus strain, host genetic factors, and various management and environmental factors.
How do you prevent EVA in horses?
Preventing and controlling equine viral arteritis
test all stallions, teasers and mares before breeding. consider vaccinating stallions against the disease – talk to your vet for advice. follow guidance on isolation and testing when importing horses.
What is a equine EVA test?
A blood test will tell whether a horse has been exposed to EVA virus. It looks for specific antibodies and a positive test result (positive titer) means that the horse has either been vaccinated for EVA or previously infected. A second test taken 10 to 14 days later will tell if the infection is active.
Is EVA contagious?
Equine viral arteritis (EVA) is a contagious disease caused by the equine arteritis virus. The virus occurs worldwide, including mainland Europe, in thoroughbred and non-thoroughbred populations.
What is Eva virus?
Equine Viral Arteritis (EVA) is a contagious disease of equids caused by equine arteritis virus (EAV), an RNA virus that is found in horse populations in many countries.
What causes EVA in horses?
Epidemiology and Transmission of Equine Viral Arteritis
Outbreaks of EVA are most often linked to the movement of infected animals or the shipment of virus-contaminated semen (chilled or frozen) and frozen embryos. Transmission of EAV can occur by respiratory, venereal, and congenital routes or by indirect means.
How do you treat EVA in horses?
If fever or swelling is severe, your veterinarian will likely prescribe non-steroidal and anti-inflammatory drugs to make the horse more comfortable. Horses should be able to return to work within 14 to 28 days. With the help of your veterinarian, EVA should never be a problem. It is a very manageable infection.
Can geldings get EVA?
The reason we in this country are keen to vaccinate stallions against EVA is that it is actually a respiratory virus primarily that can affect mares, geldings and stallions. The respiratory infection causes ‘flu-like symptoms in all horses.
What are the symptoms of equine metabolic syndrome?
Clinical signs associated with EMS include obesity, difficulty losing weight, easily gaining weight and the development of fatty deposits, particularly in the crest of the neck. EMS horses may also have increased inflammatory responses.
What happens if a horse tests positive for EIA?
As there is no known treatment for EIA and infected horses become lifelong carriers posing a risk to other horses, any horse confirmed positive for EIA must be quarantined and isolated 200 yards away from all other horses. If appropriate isolation is not available, the owner may opt for humane euthanasia.
What is Pyro horse?
Equine piroplasmosis is a tick-borne protozoal disease that affects horses and other equids. The consequences of infection may include asymptomatic carriage, an acute and potentially life-threatening illness, or chronic disease with vague clinical signs such as reduced exercise tolerance.
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.
How long are you contagious pre symptoms?
People are considered likely to be infectious from 48 hours before the onset of symptoms. To prevent the spread of the virus people who have tested positive are required to isolate for full 7 days.
How does a Coggins test work?
To perform a Coggins test, a licensed veterinarian must draw blood from the horse and send it to an accredited lab for analysis. The lab will conduct a test to detect the EIA antibody (a protein that allows the body to recognize the EIA virus; this will only be present if the horse has had the EIA virus).
Laboratory tests
Equine viral arteritis can be diagnosed by virus isolation, the detection of viral antigens or nucleic acids, and serology. In recently infected animals, equine arteritis virus may be recovered from nasal secretions, blood and semen as well as from a number of tissues and fluids at necropsy.
What causes leptospirosis in horses?
Horses become infected when mucus membranes (in their eyes, mouth, and nose) or cuts and scratches on the legs contact infected urine or blood. Horses can also become infected by ingesting hay or grain and water that has been contaminated by infected urine.
What causes a lethal white foal?
A genetic mutation found on the endothelin-B receptor gene (EDNRB) is responsible for overo lethal white foal syndrome. The mutation causes ineffective migration of neural crest cells in the developing embryo, which leads to a lack of melanocytes (pigment cells) and enteric nerve cells.
How do you treat ERU in horses?
We typically start with medical therapy to treat horses experiencing active episodes of ERU. Treatment consists of topical and systemic (oral) anti-inflammatory medications. If there is a suspicion of bacterial infection, some veterinarians will additionally prescribe an antibiotic.

Is EVA notifiable?
EVA is a notifiable viral disease that affects horses, mules and donkeys. It is notifiable in all stallions, and in mares that have been mated or inseminated within 14 days. The disease is common in warm blood horses on the continent.
Can a horse recover from EPM without treatment?
What is the prognosis for EPM? If left undiagnosed and untreated, EPM can cause devastating and lasting neurological deficits. The success rate for treated horses is high. Many will improve and a smaller percentage will recover completely, but 10-20% of cases may relapse within two years.
