The most common symptoms found in horses infected with WNV include: Fever: Mild to moderate fever of 102-103°F (38.6-39.4°C) concurrent with loss of appetite and depression. Muscle fasciculations: Fine and course fasciculations of the muscles of the horse's face and neck are most common.
These signs include ataxia (stumbling, staggering, wobbly gait, or incoordination) combined with circling, hind limb weakness, inability to stand, multiple limb paralysis, muscle fasciculation, proprioceptive deficits, blindness, lip droop/paralysis, teeth grinding, fever, or acute death.
Horses may become abnormally sensitive to sights, sounds, or touch. Once complete paralysis has developed in one or more legs, the death rate increases greatly. A presumptive diagnosis is made by a blood test showing increases in IgM-type antibodies against West Nile virus. Treatment of signs and supportive care are indicated.
