Synonym(s): California encephalitis
arthropod-borne encephalitis or encephalomeningitis, induced by an arbovirus. Infection usually is caused by a mosquito bite. Epidemics occur mainly in the Midwest, on the eastern seaboard, and in Texas and Louisiana. The virus was first isolated in California. The infection generally follows one of two clinical courses. The mild form is characterized by headache, malaise, GI symptoms, and a fever that may reach 104° F. The more severe form may be marked by a sudden onset of fever, vomiting, headaches, lethargy, and signs of neurological involvement such as loss of reflexes, disorientation, seizure, loss of consciousness, and flaccid paralysis. Recovery usually begins in 1 week. Mortality rate is very low, but a significant number of patients have neurological sequelae for 1 year or more. Treatment usually involves administration of anticonvulsant and sedative medications. See also arbovirus, encephalitis.
Epidemiology The infectious cycle is maintained in the mosquito vector, Aedes triseriatus
Prognosis Excellent; rare psychological residua
