Coggins Test Requirements in Virginia: What Every Horse Owner Must Know
July 31, 2026
If you own, ride, or transport horses in Virginia, the Coggins test is one of the most important compliance requirements you will face. Equine Infectious Anemia — also called EIA or Swamp Fever — is a contagious and infectious disease of horses characterized by a variety of symptoms related to anemia. Because the disease has no known vaccine or treatment, the response to a positive case requires euthanasia or lifetime quarantine.
Virginia regulation protects the state’s horse population from this debilitating disease by ensuring that all horses participating in events or congregating in other places have been tested and found negative for EIA. Understanding exactly when a test is required, which animals must be tested, and what happens when a horse tests positive can help you stay compliant and protect your herd.
What Is Equine Infectious Anemia (EIA) and Why It Is Regulated in Virginia
Equine infectious anemia is a viral, and sometimes fatal, disease that only affects equids — horses, ponies, zebras, mules, and donkeys. The virus remains in the blood of infected animals throughout their lifetime and may be spread from horse to horse via biting flies, mosquitoes, hypodermic needles, or blood-letting procedures.
Human-facilitated transmission through unclean or re-used needles and syringes is now the most common way EIA spreads in the United States, particularly among current or former Quarter Horse racehorses with ties to unsanctioned racing. Unlike many diseases, direct contact with an infected horse is not required for transmission, making containment challenging — EIA can spread rapidly among equines since insects are naturally attracted to areas where horses congregate, such as barns.
Most infected horses are asymptomatic, showing no signs of disease, but acutely infected animals may develop a fever, go off feed, or die suddenly. A chronically infected equine may develop non-specific signs such as weight loss, weakness, anemia, and swelling of the legs, chest, and abdomen. It may take 60 days or more for the horse to test positive after infection.
Key Insight: EIA poses no risk to human health. According to the USDA Animal and Plant Health Inspection Service, the virus is not a zoonotic threat, meaning it cannot be transmitted to people.
EIA can have serious consequences for horses, their owners, and the vitality of Virginia’s horse industry. For this reason, the State Veterinarian recommends that all horses be tested for EIA annually. Virginia’s regulatory framework for EIA control is codified under 2VAC5-70 of the Virginia Administrative Code.
Which Animals Require a Coggins Test in Virginia
Under Virginia’s regulatory definitions, “horse” includes all horselike animals embracing all members of the equine species including horses, ponies, the asinine species, and burros. It also includes hybrid offspring of the equine and asinine species by whatever name they may be known, such as mules, hinnies, and donkeys.
The Coggins test is the laboratory test performed to detect EIA infections in the animals susceptible to the virus, which includes horses, ponies, mules, and donkeys. In short, if the animal is a member of the equine family, Virginia’s testing rules apply whenever that animal is assembled with equines owned by other people.
One important exemption applies to very young foals. Foals under 6 months of age with a negative-tested dam are exempt from the import testing requirement. However, once a foal reaches the age threshold or is separated from its dam, standard testing rules apply.
- Horses of all breeds and sizes
- Ponies
- Mules and hinnies
- Donkeys and burros
- Any other member of the genus Equus
If you board horses at a facility where animals from multiple owners are kept together, or if you participate in any organized riding activity on shared land, every equine you bring must have a current negative Coggins certificate on file.
When a Coggins Test Is Required in Virginia
All horses assembled at a show, fair, race meet, or other such function, or participating in any activity on properties where horses belonging to different owners may come into contact with each other in Virginia, must be accompanied by a report of an official negative test for equine infectious anemia. The test shall be conducted by an approved laboratory on a sample taken by an accredited veterinarian or a State-Federal Regulatory Veterinarian within 365 days prior to such event or activity.
Any organized equine show, sale, exhibition, contest, fair, trail ride, parade, wagon train, charity or social event, or any other occurrence at which any number of horses of more than one owner are gathered, is considered to be an equine event and proof of a valid negative Coggins is required.
The regulation also extends to informal recreational settings. The language in 2VAC5-70-20 was amended to clarify that the testing requirements apply to any activity on properties where horses owned by two or more owners may come into contact with each other, such as in state parks. This means trail rides on public land with friends who own their own horses trigger the same requirement as a formal show.
Pro Tip: You do not need to carry your Coggins certificate while riding. Horse owners do not need to carry the certificate with them while riding, as it may be kept in their vehicle or trailer. Keep a digital copy accessible on your phone as a backup.
Coggins test certificates are valid for 12 months from the date the blood sample was drawn from the horse. A legible paper or digital copy of an original Coggins test is acceptable under Virginia law, unless an event organizer specifically requires an original for that event.

How the Coggins Test Works and Approved Testing Methods in Virginia
“Official test” under Virginia regulation means the agar gel immunodiffusion test — the Coggins AGID. This blood-based diagnostic has been the standard for EIA detection in the United States since it was developed in 1970 and remains the test recognized under Virginia’s administrative code.
A licensed veterinarian must complete the collection of the blood, a physical examination of the horse, and take pictures of the horse as part of the testing process. Only Category II accredited veterinarians, who are authorized to perform accredited duties in the state in which samples are collected, may submit samples to an APHIS-approved laboratory.
Once the veterinarian has drawn blood from the horse, it is sent to an approved laboratory for testing. Most labs will have results returned to the veterinarian and/or horse owner within five business days. If travel is required before then, labs can rush the results for an additional fee.
Starting April 15, 2020, all veterinarians and laboratories must use USDA-approved EIA test forms for regulatory compliance. Accredited veterinarians must complete a VS 10-11 form either electronically or by paper using one of the USDA-approved systems or forms and submit samples to APHIS-approved labs. Digital submission platforms such as GlobalVetLink are USDA-approved and accepted for regulatory compliance in Virginia.
Important Note: The AGID (Coggins) test is the only “official test” named in 2VAC5-70. If a veterinarian or laboratory offers an alternative EIA detection method, confirm with the Virginia Department of Agriculture and Consumer Services (VDACS) that it meets the state’s regulatory definition before relying on it for event entry or interstate movement.
Interstate Movement and Import Requirements in Virginia
When bringing horses into Virginia from another state, the documentation requirements go beyond a Coggins certificate alone. Horses entering Virginia require a CVI or Extended Equine Certificate of Veterinary Inspection and must test negative for Equine Infectious Anemia within the past 12 months.
Before transporting animals into Virginia, you must obtain a Certificate of Veterinary Inspection (CVI) and, in some cases, a permit. Virginia accepts CVIs from several approved electronic platforms, and using these electronic platforms helps ensure compliance and smooth transport across state lines and may negate the need for a permit.
For horse owners who travel frequently across state lines, Virginia participates in the Extended Equine Certificate of Veterinary Inspection (EECVI) program. The EECVI allows horse owners traveling out of state with their animals for horse shows, trail riding, and festivals to obtain a CVI that is valid for six months from the CVI inspection date or the Coggins test expiration date, whichever comes first.
Virginia horses may travel to 28 states on an EECVI. The EECVI is only available online through GlobalVetLink, and prior to each movement, the owner must record movement information into the GlobalVetLink database and obtain a Health Declaration and Movement Permit (HDMP). In order for the EECVI to remain valid, the Coggins test form and the HDMP must be kept together, though official digital copies are acceptable.
| Document | Validity Period | Use Case |
|---|---|---|
| Coggins (AGID) Certificate | 12 months from blood draw | In-state events, interstate travel |
| Standard CVI | 30 days from issuance | Interstate movement into Virginia |
| EECVI | 6 months (or Coggins expiration, whichever is sooner) | Repeated out-of-state travel to 28 participating states |
An “interstate health certificate” under Virginia law means a legible record covering the health requirements for importing of horses into Virginia, executed on an approved form of the state of origin, and bearing the endorsement of the livestock health official of that state. Always confirm the destination state’s specific requirements before departure, as individual states may have additional rules beyond Virginia’s baseline.
What Happens When a Horse Tests Positive in Virginia
A positive EIA test result sets a mandatory regulatory process in motion. EIA is a regulated disease in the United States, and by law, laboratories must report positive EIA test results to state and federal animal health officials within two days. In Virginia, that notification goes to VDACS and the USDA-APHIS simultaneously.
A “reactor” under Virginia regulation means a horse over eight months of age that reacts positively to an official test performed by an approved laboratory. Once a horse is classified as a reactor, the State Veterinarian’s office takes direct oversight of the case.
The following steps occur after a confirmed positive result under 2VAC5-70:
- Permanent identification: Reactor animals must be permanently identified by a freeze brand, using the official Commonwealth of Virginia code identification (52A) placed under the mane. The branding is performed by or under the supervision of a representative of the State Veterinarian.
- Quarantine of the premises: Negative horses on the premises where a reactor animal is disclosed may not be removed from such premises without the approval of the State Veterinarian.
- Additional herd testing: Required testing will be performed to detect additional infection and to confirm the identity of the reactors, under the supervision of a representative of the State Veterinarian. Additional testing may be required by the State Veterinarian to clarify the EIA status of horses on the premises.
- Foal retesting: Virginia horses under eight months of age that have reacted to the official test shall be placed under written quarantine and retested when they become eight months of age.
Infected animals that survive the disease become virus carriers and can infect other equids for life. They must either be euthanized or permanently isolated from other equids to prevent transmission. Carriers may also experience clinical flare-ups, often following stress or strenuous work.
Quarantine, Euthanasia, and Isolation Rules in Virginia
Virginia’s regulations give the owner two options once a horse is confirmed as a reactor: euthanasia or lifetime quarantine. At the owner’s option, reactor horses may be retained under quarantine and held in isolation from all other horses on the premises. Provisions may be made under terms specified by the State Veterinarian for the use of such reactor animals by the owner or his agent in such a manner that there is no risk of spreading equine infectious anemia. The terms and conditions shall be made part of the quarantine document.
The restrictions placed on the movement and maintenance of reactor animals shall be permanent or until such animals die, are destroyed, or are cleansed of the carrier state. In practice, this means a positive horse cannot be sold, moved, or used in any setting involving other horses without explicit State Veterinarian approval.
The physical isolation standard is strict. Options for an EIA positive horse are euthanasia or lifetime quarantine with permanent isolation at least 200 yards away from non-infected horses. These measures include confinement in a screened stall and a 200-yard buffer from all other horses. Often, owners elect to euthanize their horses rather than subjecting them to such strict isolation.
When reactor animals are quarantined, all other horses on the premises may be required to be tested every six months if deemed necessary by the State Veterinarian. All testing shall be at the owner’s expense unless otherwise authorized by the State Veterinarian.
Important Note: Federal and state health agencies, as well as the American Association of Equine Practitioners, support euthanasia as the most prudent option when a horse tests positive. If you face this situation, contact VDACS and your accredited veterinarian immediately for guidance specific to your circumstances.
Virginia’s approach to positive-case management aligns with federal USDA-APHIS standards. You can review the national framework in the AAEP Infectious Disease Guidelines for Equine Infectious Anemia, which outlines the minimum standards followed by state programs across the country.
Penalties for Non-Compliance in Virginia
Failing to comply with Virginia’s EIA testing requirements is not a minor oversight — it carries legal consequences at both the event level and the state enforcement level. Under 2VAC5-70, the regulatory framework gives event organizers and state officials authority to act immediately when a horse lacks proper documentation.
The person in charge of an event must ensure that a copy of the official negative test results accompanies each horse in the event or activity, and shall make such reports available for inspection by a representative of the State Veterinarian upon request. The person in charge shall exclude any horse that is not accompanied by a negative test report.
This means event managers bear direct legal responsibility for enforcing Coggins compliance at the gate. The event manager is subject to notification prior to the event from the State Veterinarian’s Office to provide documentation in the form of a report confirming that each horse at the event has a valid negative Coggins test. Reports may be submitted as legible copies of each Coggins, a legibly completed Equine Event Report Form, or a similar legible report containing the same information, mailed in hard copy or electronically.
At the owner level, transporting a horse across state lines without proper documentation exposes you to significant financial risk. Depending on the state, owners can face fines of up to $25,000 or more per horse for non-compliant interstate movement. Virginia’s own enforcement authority under the Virginia Department of Agriculture and Consumer Services allows VDACS to pursue civil penalties against owners who violate the state’s animal health regulations.
- Horses without a valid Coggins certificate must be turned away from any equine event
- Event managers who fail to enforce the requirement may face regulatory action from VDACS
- Moving a horse interstate without a current Coggins and CVI can result in fines, quarantine orders, and forced return of the animal
- Knowingly transporting a reactor horse without State Veterinarian approval violates both state and federal animal health law
The most straightforward way to avoid penalties is to schedule annual Coggins testing as part of your horse’s routine veterinary care. VDACS recommends having a Coggins test performed on equines annually. Keeping digital copies of current certificates accessible at all times — in your trailer, on your phone, or through a platform like GlobalVetLink — ensures you are never caught without documentation at a gate or checkpoint.
