Ardèche, France – Authorities have confirmed a second case of Equine Infectious Anemia (EIA), commonly known as swamp fever, in the Ardèche department. The National Reference Laboratory of the National Food, Environment and Labor safety Agency (ANSES) identified the disease in a two-year-old horse. This follows a previous confirmed case in the same region in May.
Silent Carrier and Control Measures
the affected horse exhibited no outward symptoms of the illness,but tested positive during routine monitoring of the equine facility where it resided. To prevent further spread of this highly contagious disease,the animal was humanely euthanized.Increased scrutiny of the affected establishment will continue for at least 90 days, with intensified monitoring protocols.
Understanding Equine Infectious Anemia
Equine Infectious anemia is a viral disease that solely impacts equines – horses, donkeys, and mules. Currently, there is no vaccine available to prevent infection.the primary modes of transmission include biting flies, contaminated needles or medical equipment, and through breeding via infected semen. Importantly,direct equine-to-equine transmission,outside of these vectors,is rare.
Once an equine is infected with EIA, it becomes a lifelong carrier of the virus. While an animal might experience intermittent symptoms like fever and weight loss,it can also remain clinically normal while continuously shedding the virus,posing a risk to other horses. There is no known cure to eliminate the virus from an infected animal.
Key Facts About Equine Infectious Anemia
| Characteristic | Details |
|---|---|
| Affected Animals | Horses, donkeys, and mules exclusively |
| Transmission | Biting flies, contaminated needles, infected semen |
| Prevention | No vaccine; relies on management and testing |
| Lifelong Status | Infected animals remain carriers for life |
Did You Know? Equine Infectious Anemia was first recognized in the United States in the early 1970s and has since become a global concern for horse owners and breeders.
Pro Tip: Regular veterinary checkups and strict biosecurity measures,like using dedicated equipment for each horse,are crucial for preventing the spread of EIA.
Authorities are urging horse owners in the Ardèche region to remain vigilant and report any signs of illness in their animals immediately. Continuous monitoring and prompt action are essential in controlling this potentially devastating disease.

Long-Term Management of Equine Infectious Anemia
managing EIA requires a multifaceted approach. Routine testing, notably for horses that travel or interact with new animals, is vital. The American Association of Equine Practitioners (AAEP) provides extensive guidelines on EIA prevention and control, emphasizing the importance of biosecurity protocols on equine facilities.

Recent advancements in diagnostic testing have improved the accuracy and speed of EIA detection. However, ongoing research is needed to develop effective treatments or a vaccine to combat this persistent viral disease.
Frequently Asked Questions About Equine Infectious Anemia
- what is equine infectious anemia? It’s a viral disease affecting equines (horses,donkeys,mules) that can cause lifelong infection.
- How is EIA transmitted? Primarily through biting flies, contaminated needles, and infected semen.
- Are there any symptoms of EIA? Symptoms can vary,including fever,weight loss,and anemia,but some horses show no signs.
- Is there a cure for equine infectious anemia? Regrettably, there is currently no cure for EIA.
- Can EIA be prevented? While there’s no vaccine, strict biosecurity measures and regular testing can help prevent spread.
- what should I do if I suspect my horse has EIA? Contact your veterinarian immediately for testing and guidance.
- How long does a horse stay infectious after contracting EIA? Infected horses remain carriers for life, intermittently shedding the virus.

What are the primary ways Equine Infectious Anemia (EIA) spreads between horses?
Ardèche Reports First Case of Equine Infectious Anemia in Horse in 2025
Understanding Equine Infectious Anemia (EIA)
Equine Infectious Anemia (EIA), often called swamp fever, is a viral disease affecting horses, donkeys, and mules. The recent confirmation of the first case in Ardèche, France, in 2025, is a critical alert for horse owners and veterinary professionals across the region and beyond.Understanding the disease, its transmission, and preventative measures is paramount. The term “equine” itself, as defined in resources like dict.cc, directly relates to horses and their characteristics, making understanding equine health vital.
How EIA Spreads: Transmission Routes
EIA is primarily spread through blood-to-blood contact. This can occur in several ways:
Insect Bites: The most common route of transmission is via biting insects, particularly horseflies and deerflies, which can mechanically transmit the virus.
Contaminated Equipment: Sharing needles, syringes, dental floats, or other equipment used on infected horses can spread the virus.
Transplacental Transmission: A mare infected with EIA can transmit the virus to her foal during pregnancy.
Artificial Insemination: Using semen from an infected stallion poses a risk.
Rarely, through wounds that directly connect the circulatory systems of two horses.
The ardèche Case: Details and Response
On September 9th, 2025, the Ardèche regional veterinary services confirmed the first case of EIA in a horse within the department. The affected horse,a 7-year-old Selle Français gelding used for recreational riding,presented with symptoms including:
Fever: A persistent,elevated body temperature.
Anemia: A reduction in red blood cells, leading to weakness and fatigue.
Weight Loss: unexplained and progressive loss of body mass.
Swelling: Edema, particularly in the legs and abdomen.
Following a routine health check, suspicion arose, prompting diagnostic testing. The Coggins test, a widely used screening method for EIA, returned a positive result, which was subsequently confirmed by PCR testing at the national reference laboratory.
Immediate action was taken:
- Quarantine: The infected horse was promptly placed under strict quarantine.
- Tracing: A thorough investigation is underway to trace all horses that may have had contact with the infected animal.
- Testing: All potentially exposed horses are being tested for EIA.
- movement Restrictions: Temporary movement restrictions have been implemented in the immediate vicinity of the affected property.
Diagnosing Equine Infectious Anemia
Early and accurate diagnosis is crucial for controlling EIA. Several diagnostic tests are available:
Coggins Test (Agar Gel Immunodiffusion – AGID): The traditional screening test, known for its reliability but can sometimes produce false positives.
ELISA (Enzyme-Linked Immunosorbent Assay): A more sensitive and specific test than the Coggins test.
PCR (Polymerase Chain Reaction): The most accurate test, detecting the viral genetic material directly. PCR is frequently enough used to confirm positive results from other tests.
Immunoblot: A confirmatory test used to resolve discrepancies.
Regular testing, particularly for horses that travel or commingle with other horses, is strongly recommended.
Managing and Preventing EIA: A Proactive Approach
Currently, there is no cure for EIA.Management focuses on preventing the spread of the disease and providing supportive care to affected animals.
Prevention Strategies:
Strict Insect Control: Implement robust fly control measures,including stable cleaning,fly sprays,and fans.
Biosecurity Protocols: Practice strict biosecurity on farms and stables. This includes disinfecting equipment between horses, isolating new arrivals, and controlling access.
Regular Testing: Annual or bi-annual EIA testing is vital,especially for horses that travel,compete,or are boarded.
Safe Needle Practices: Never reuse needles or syringes.
Quarantine New Horses: Isolate new horses for at least 30 days and test them for EIA before introducing them to the existing herd.
Responsible Breeding Practices: Ensure stallions used for breeding are regularly tested and free of EIA.
Managing Infected Horses:
Euthanasia: Due to the lack of a cure and the risk of transmission, euthanasia is often recommended for horses diagnosed with EIA.
Lifetime Quarantine: In some cases, horses can be kept in strict, lifelong quarantine to prevent further spread. This requires a secure, isolated environment and meticulous biosecurity measures.
