Q fever was diagnosed in a previously healthy man who had recently traveled to the East Coast of Australia. The patient experienced fever and headache accompanied by lymphopenia and elevated liver enzymes but not pneumonia. He had no known direct exposures to animals, exhibited IgM and IgG seroconversion to phase II antigen of Coxiella burnetii and IgM only to phase I antigen, and responded to doxycycline treatment. This case serves as a reminder to clinicians to consider Q fever in the differential diagnosis of acute febrile illness in travelers returning from endemic areas.
一名近期前往澳大利亚东海岸的既往健康男子被诊断为Q热。该患者出现发热和头痛，伴有淋巴细胞减少和肝酶升高，但无肺炎症状。他没有已知的直接动物接触史，针对伯氏考克斯体II期抗原出现IgM和IgG血清学转换，仅针对I期抗原出现IgM，并且对多西环素治疗有反应。该病例提醒临床医生，对于从流行地区返回的旅行者出现的急性发热性疾病进行鉴别诊断时应考虑Q热。
