There is no cure for EHV, but supportive care improves outcomes dramatically.

Typical treatment includes:

• Anti-inflammatory medications
• Fluids for hydration
• Antiviral medications in some cases
• Bladder support for neurologic horses

Most respiratory cases recover fully with rest. Neurologic cases require intensive care, sling support in some situations, and close monitoring.

Recovery timelines vary:

• Respiratory cases: 2–4 weeks
• Neurologic cases: Weeks to months
