In February 2006, a diagnosis of sylvatic epidemic typhus in a counselor at a wilderness camp in Pennsylvania prompted a retrospective investigation. From January 2004 through January 2006, 3 more cases were identified. All had been counselors at the camp and had experienced febrile illness with myalgia, chills, and sweats; 2 had been hospitalized. All patients had slept in the same cabin and reported having seen and heard flying squirrels inside the wall adjacent to their bed. Serum from each patient had evidence of infection with Rickettsia prowazekii. Analysis of blood and tissue from 14 southern flying squirrels trapped in the woodlands around the cabin indicated that 71% were infected with R. prowazekii. Education and control measures to exclude flying squirrels from housing are essential to reduce the likelihood of sylvatic epidemic typhus.
2006年2月，宾夕法尼亚州一个野外营地的一名辅导员被诊断为丛林型流行性斑疹伤寒，从而引发了一项回顾性调查。从2004年1月到2006年1月，又确诊了3例。所有患者均为该营地的辅导员，都经历过伴有肌痛、寒战和出汗的发热性疾病；其中2人曾住院治疗。所有患者都睡在同一间小屋里，并报告说在床边墙壁内看到并听到有松鼠。每位患者的血清都有感染普氏立克次体的证据。对在小屋周围林地捕获的14只南方松鼠的血液和组织进行分析表明，71%的松鼠感染了普氏立克次体。采取教育和控制措施，防止松鼠进入房屋，对于降低丛林型流行性斑疹伤寒的发病几率至关重要。
