After an incubation period of 3 to 15 days, symptoms of the West Nile Virus often replicate the flu, beginning with headache, fever and body aches. Most infections are mild. Skin rash and swollen lymph glands may accompany these symptoms.
Severe infection is marked by headache, high fever, neck stiffness, disorientation, tremors, muscle weakness, paralysis, and rarely, death. Persons over 50 carry the highest risk for getting the disease.
A physician should be consulted immediately for any health concerns.
