Outdoors, sunlight and airflow help break down viral particles.
Indoors, the story changes dramatically.
EHV can persist on:
- Stall walls and latches
- Water buckets
- Halters and lead ropes
- Brooms, rakes, pitchforks
- Shared tack and grooming kits
- Trailer dividers and tie rings
The virus survives longer in:
- Cold, moist environments
- Poorly ventilated barns
- High-traffic stalls and shared spaces
This is why winter show seasons and high-density stabling environments are often associated with larger outbreaks.
Disinfecting with proven virucidal agents—like accelerated hydrogen peroxide or freshly mixed bleach—is essential, but contact time matters. A quick wipe is not enough.
