West Nile Virus

This annual vaccination for all horses is strongly recommended.

The West Nile virus causes inflammation of the central nervous system. Because the virus has been identified in the entire continental United States, as well as Mexico and Canada and complete mosquito control is not possible, all horses are considered at risk.

TRANSMISSION: Mosquitoes and, rarely, other bloodsucking insects spread this disease after feeding on birds infected with West Nile virus

CLINICAL SIGNS: Fever, lethargy, weakness, blindness, muscle fasciculations, difficulty walking and seizures. Those that survive often retain behavioral and gait abnormalities.

FATALITY: Approximately 33%1

PREVENTION: Initial vaccination series with CORE EQ INNOVATORTM followed by annual spring revaccination prior to mosquito season
