St. Louis encephalitis (SLE) virus was isolated from a 21-year-old female hospitalized on 4 October 1978 in Belem, Brazil. Symptomatology on admission included fever, chills, severe headache, abdominal pain, myalgia, arthralgia and jaundice. SLE virus was isolated from her blood drawn on the 8th day of illness and subsequent seroconversion was documented. Serological tests showed the isolate to be closely related to the Belem prototype of SLE virus but distinct from other flaviviruses tested. The patient was discharged without sequelae after 16 days of hospitalization. Epidemiological investigations where the patient worked and lived revealed no evidence of extensive transmission of SLE virus.
