St. Louis encephalitis (SLE) virus was isolated from a 21-year-old female hospitalized on 4 October 1978 in Belém, 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 Belém 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.
1978年10月4日，在巴西贝伦，从一名住院的21岁女性身上分离出圣路易斯脑炎（SLE）病毒。入院时的症状包括发热、寒战、严重头痛、腹痛、肌痛、关节痛和黄疸。在患病第8天采集的血液中分离出SLE病毒，并记录到随后的血清转化。血清学检测表明，该分离株与SLE病毒的贝伦原型密切相关，但与所检测的其他黄病毒不同。患者住院16天后出院，无后遗症。对患者工作和生活地点的流行病学调查未发现SLE病毒广泛传播的证据。
