As concern continues to rise surrounding the recent equine herpesvirus (EHV-1) outbreak, veterinarians at Brazos Valley Equine Hospital (Navasota) offered important guidance during a live Q&A session. Their recommendations aim to help horse owners, trainers and event producers make informed decisions to protect equine health and reduce further spread.
Below is a breakdown of the key points addressed by BVH veterinarians:
Should producers cancel events this weekend?
Yes. BVH strongly recommends canceling to limit horse movement and reduce transmission risk.
How should neighboring states approach horse events?
Limiting travel is critical. Less horse movement equals faster outbreak control.
Are cases confirmed outside of the Waco horses?
At this time, BVH is only aware of the Waco-associated cases, though spread is possible.
Is EHV contagious to humans?
No. EHV does not infect people.
Can race attendees get horses tested at the clinic?
Yes. BVH is offering screening and trailer-side examinations.
How should other disciplines respond?
Responses should be tailored to each discipline, but all should focus on:
- Vaccination
- Temperature monitoring
- Strong biosecurity practices
Can farriers spread EHV barn to barn?
BVH says unlikely, as most farriers follow careful infectious-disease protocols.
How can owners get vaccines without hauling to the clinic?
A veterinary exam is required for vaccination. BVH can perform these exams in-clinic or on-farm.
When should boosters be given?
If it has been more than 90 days since your horse’s last EHV vaccination, BVH recommends boosting as soon as possible to increase antibody levels.
What disinfectants should be used?
BVH advises against using bleach. Instead, use:
- Accelerated hydrogen peroxide
- Phenols
- Quaternary ammonium products
(Products like Rescue or Companion fall into these categories.)
How long does the virus survive on surfaces?
- Dry surfaces: up to 2 days
- Wet surfaces: up to 2 weeks
Can horses carry the virus without showing symptoms?
Yes. Horses can be contagious even without fever or nasal discharge.
Do supplements like lysine or zinc help immunity?
No. BVH reports no evidence that lysine or zinc reduce risk or severity. Vaccination remains the best tool.
What is a normal horse temperature?
99–101.5°F, depending on conditions.
Is it safe to ride at home if a horse was exposed but is asymptomatic?
Yes, but owners should:
- Keep exposed horses separated from others
- Avoid sharing tack or equipment
Should unvaccinated horses with recent exposure get vaccinated now?
Yes. Vaccination may help reduce virus shedding and slow spread.
