During an outbreak, fever is often the first red flag. Many barns catch EHV early simply by taking temperatures twice a day.
Common early signs
- Fever above 101.5°F
- Nasal discharge
- Lethargy or unusual quietness
- Coughing or reduced appetite
Neurologic (EHM) symptoms
- Hind-limb weakness
- Stumbling or wobbly gait
- Difficulty urinating
- Inability to stand
These neurologic cases require immediate veterinary intervention.
