Protect Your Horses
Disease activity shifts week to week. A few habits go a long way:
- Check destination states for disease activity before you travel or compete
- Isolate returning horses for 14–21 days when possible
- Monitor temperatures daily — fever is often the first sign of EHV-1
- Avoid nose-to-nose contact and don't share water buckets or equipment at events
- Inspect wounds daily and keep them clean and covered
