Symptoms Of Infection

 

 

 

Question: Are You Symptomatic?

Answer: Most people who are infected with the West Nile virus will not have any type of illness. It is estimated that 20% of the people who become infected will develop West Nile fever: mild symptoms, including fever, headache, and body aches, occasionally with a skin rash on the trunk of the body and swollen lymph glands. The symptoms of severe infection (West Nile encephalitis or meningitis) include headache, high fever, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, and paralysis. It is estimated that 1 in 150 persons infected with the West Nile virus will develop a more severe form of disease.

 

Question: What is the incubation period in humans (i.e., time from infection to onset of disease symptoms) for West Nile encephalitis?

Answer: Usually 3 to 14 days. Q. How long do symptoms last? A. Symptoms of mild disease will generally last a few days. Symptoms of severe disease may last several weeks, although neurological effects may be permanent.
