Western Equine Encephalomyelitis
Western equine encephalomyelitis (WEE) is a viral disease that can attack your horse’s nervous system.

TRANSMISSION: Infected mosquitoes
CLINICAL SIGNS: Loss of appetite, fever, depression, head pressing, teeth grinding, circling, blindness and seizures. Surviving horses often have residual mental dullness.
FATALITY: Approximately 50% for WEE1
PREVENTION: CORE EQ INNOVATORTM followed by annual spring revaccination prior to mosquito season
