Wow, how are we in December already?

The current EHV-1 reported case total associated with the Waco, TX outbreak is 46, 33 of which are the EHM/neurologic form. Affected states at this time include Texas, Oklahoma, Louisiana, South Dakota, Colorado, New Mexico, Arizona and Washington state. There are not reported numbers of mortalities to present.

There have been additional reports of EHM in MD (11/18) and PA (11/27) that are not associated with the Waco, TX outbreak. This is 𝐧𝐨𝐭 an abnormal pattern for this disease, as spontaneous outbreaks are known to happen, especially if there is a gathering of younger horses for an event, sale, etc.

Though many western performance events have either been cancelled or rescheduled, it continues to be important to practice good biosecurity and monitoring while traveling and at home. Additionally, it is important to remember that any horse can contract and/or spread Equine Herpesvirus 1 - it is not limited to barrel horses. Horses that have been at events or are traveling should have their temperature monitored at least twice daily (morning and evening) and have their own sets of equipment, buckets, etc. - refer back to our recent post on biosecurity for more tips on how to avoid infectious disease spread.

At any rate, as the outbreak situation continues to develop, transport recommendations have been evolving state by state. Not all states with positive cases have travel restrictions.

If you are traveling, you and your veterinarian should contact the destination state department of agriculture/state veterinarian for the most current regulations. Additional states may require supplemental statements on CVIs/health certificates - it is recommended to contact the destination state when traveling to find out the most current regulations.

The current EHV-1 case total associated with the Waco, TX outbreak is 32, 26 of which are the EHM/neurologic form. Affected states at this time include Texas, Oklahoma, Louisiana, South Dakota, Colorado, New Mexico, Arizona and Washington state. There are not reported numbers of mortalities to present.

What do we predict will happen over the next few weeks? Dr. Buchanan at Brazos Valley Equine has put together a great explanation of what we can expect as far as timeline, waves of the virus and how exposure is defined. This is why we will still expect to see new fevers and new cases, and why continued monitoring and biosecurity practices remain crucial so we can mitigate disease spread. Rather than continue to panic and cause distress, this is an expected flow of EHV and we can continue to all slow spread and identify cases to the best of our ability.

The total cases reported at this time do appear to skew the numbers and make it seem like there is a significant amount of horses with EHM over the respiratory form of EHV-1, however we know that the majority of exposed horses will not develop neurologic disease. Additionally, cases are likely under-reported and all exposed horses may not be getting tested.

The current EHV-1 confirmed case count is 27, with 21 of those cases being the EHM (neurologic) form of the disease. The affected states are Texas, Oklahoma, Louisiana, Colorado, New Mexico, Arizona and Washington state.

There has been a significant amount of speculation on how high the case load actually is. It is important to remember that while there is a delay in positive test reporting, all owners may not necessarily choose to have their animals tested. Additionally, it was speculated that some animals passed prior to testing being performed, falsely decreasing positive numbers. It is quite important to realize that there is no way to verify these speculations without data present, which was the instigator for this series to be written - we’d like to keep you all up to date on the facts that have been presented. These outbreak situations are stressful enough as it is without guesswork and the proverbial social media firestorm that is happening as a result. The fact of the matter is, we all only what want is best for our horses & to keep them safe.

That being said, Arizona and Nevada continue to be the only states with updated travel regulations.

𝐀𝐫𝐢𝐳𝐨𝐧𝐚 (𝐫𝐞𝐥𝐞𝐚𝐬𝐞𝐝 𝟏𝟏/𝟏𝟗)

- Previous 30-day health certificates will only be valid for 5 days if the origin state has had an EHV-1/EHM detection in the previous 30 days
- Supplemental statements are required on the health certificates (found here: https://agriculture.az.gov/sites/default/files/Letterhead%20Color-NEW%20LOGO-MOVEMENT%20RESTRICTIONS-SIGNED.pdf)
- Extended (6-month passports) health certificates are cancelled and availability will be paused for the next 30 days
- Additional rules due to early November vesicular stomatitis outbreak listed on site

𝐍𝐞𝐯𝐚𝐝𝐚 (𝐫𝐞𝐥𝐞𝐚𝐬𝐞𝐝 𝟏𝟏/𝟏𝟗)

- Implementation of an Entry Permit System - All health certificates (CVIs), test results and supporting documents must be faxed/emailed to the permit office for review, then details submitted to the online permit system to obtain an entry permit number
- Entry permits will be required until January 1, 2026
- Health certificates must have supplemental statements (Found here https://agri.nv.gov/Animals/Animal_Disease/Import_Requirements/)
- Animals will be denied entry if they have been on a premise or at an event with a confirmed case of EHV-1/EHM in the last 21 days ( Extraco Events Center, 377 Arena, Lazy E Arena, Jackson County)
- Additional rules due to early November vesicular stomatitis outbreak listed on site

The National Finals Rodeo & Junior National Finals Rodeo is planning on continuing as scheduled with additional rules & regulations in place with the safety of their equine athletes at the forefront.

Major events that are being postponed or rescheduled include the Kimes Ranch Million Dollar Breakaway and the 2025 National Finals Breakaway Roping. A significant number of large barrel races, professional rodeos, horse sales and other western performance events have also been cancelled in multiple states in an effort to reduce spread during this time.

Update:

MT Dept of Ag has released the following regulations:

“- All equines entering Montana must be traveling on a certificate of veterinary inspection (CVI) issued no earlier than 72 hours prior to travel into Montana. This 72-hour restriction also applies to equines who are issued a CVI in Montana to travel out-of-state and are returning to Montana on the same CVI.
- Equines that may have been exposed to EHV-1 within 14 days prior to CVI inspection are not eligible for importation into Montana until this order is lifted.
- Equines exhibiting any clinical signs consistent with EHV-1 or EHM, including a fever, are not eligible for importation into Montana until this Order is lifted.
- All other importation requirements for equines eligible for entry into Montana pursuant to this Order remain in place

🚨 𝐄𝐇𝐕 𝐔𝐩𝐝𝐚𝐭𝐞 – 𝐒𝐭𝐚𝐲 𝐈𝐧𝐟𝐨𝐫𝐦𝐞𝐝 🚨

Horses in Oklahoma have tested positive for Equine Herpesvirus (EHV), a highly contagious viral disease. It spreads easily through nasal discharge, shared equipment, trailers, stalls, and even human contact. Horses can carry the virus before showing symptoms, so strict quarantine is essential.

𝐖𝐚𝐭𝐜𝐡 𝐟𝐨𝐫 𝐬𝐢𝐠𝐧𝐬:
🐴 Respiratory: cough, clear nasal discharge, fever
🐴 Neurologic (EHM): hind-limb weakness, incoordination, urine dribbling, tail weakness, sudden inability to stand
🐴 Reproductive: late-term abortion in mares

𝐈𝐟 𝐲𝐨𝐮𝐫 𝐡𝐨𝐫𝐬𝐞 𝐬𝐡𝐨𝐰𝐬 𝐬𝐢𝐠𝐧𝐬:
✅ Call your vet immediately
✅ Quarantine symptomatic or exposed horses
✅ Monitor all horses’ temps twice daily (Normal = 99–101.5°F)
✅ Follow strict biosecurity measures

𝐅𝐨𝐫 𝐂𝐥𝐢𝐧𝐢𝐜𝐬 – 𝐏𝐫𝐨𝐭𝐞𝐜𝐭 𝐲𝐨𝐮𝐫 𝐩𝐚𝐭𝐢𝐞𝐧𝐭𝐬:
🏥 Place signage on the door asking horse owners to inform your team if they have attended any of the affected events. If they have, please instruct them to wait outside so appropriate precautions can be taken.
🏥Take a detailed history of potential exposure and travel
🏥 Examine and take the patient’s temperature 𝗕𝗲𝗳𝗼𝗿𝗲 entering the clinic
🏥 Antiviral medications can be given prophylactically to exposed horses to reduce the risk of developing EHM. For more information regarding this treatment, please reach out to our equine internal medicine team.

🩺 Stay vigilant, protect your herd, and work closely with your veterinarian.
