Clinical Signs: The mare became acutely recumbent on Feb. 10, 2026. She was assisted to stand and moved to an isolation area, treated supportively, remained stable overnight, became recumbent the following morning but has improved since then. Her ataxia is markedly improved but she still appears to have some urinary incontinence. Nasal swab and blood samples were positive for EHV-1 by PCR.
