Flavivirus encephalitis (health)


Encephalitis (inflammation of the brain) due to a flavivirus, a virus transmitted by a mosquito or tick. Flavivirus encephalitis includes West Nile fever, Japanese encephalitis, St. Louis encephalitis, and Murray Valley encephalitis. These diseases typically develop after an incubation period of 5 to 15 days. The neurologic manifestations depend on which part of the nervous system is infected -- the meninges (to cause meningitis), the body of the brain (encephalitis), or the spinal cord (myelitis). The more important features include a reduced level of consciousness, which may be associated with seizures, a flaccid (floppy) paralysis resembling that of poliomyelitis, and parkinsonian movement disorders.
