蜱传回归热（TBRF）是一种潜在的严重螺旋体感染引起的某些物种的疏螺旋体和收购通过叮咬Ornithodoros蜱。2017年，德克萨斯州奥斯汀公共卫生部门在洞穴工作的员工中发现了5例发热性疾病。一个横截面serosurvey和访谈进行了44名员工在8个组织进行洞穴相关的工作。在五名参与者的血清中检测到针对引起TBRF的疏螺旋体的抗体，其中四人报告最近患病。血清阳性员工进入洞穴的次数显著多于血清阴性员工（中位数25 [SD：15] vs中位数4 [SD：16]，p = 0.04）。六个洞穴更频繁地被血清反应阳性的雇员进入，构成潜在的高风险。这些洞穴中有几个是在公共使用区，并开放给图尔斯参观。建议对地区医疗保健提供者进行有关TBRF的教育，并为洞穴探险者和公众提供预防建议。
Tick-borne relapsing fever (TBRF) is a potentially serious spirochetal infection caused by certain species of Borrelia and acquired through the bite of Ornithodoros ticks. In 2017, Austin Public Health, Austin, TX, identified five cases of febrile illness among employees who worked in caves. A cross-sectional serosurvey and interview were conducted for 44 employees at eight organizations that conduct cave-related work. Antibodies against TBRF-causing Borrelia were detected in the serum of five participants, four of whom reported recent illness. Seropositive employees entered significantly more caves (Median 25 [SD: 15] versus Median 4 [SD: 16], p = 0.04) than seronegative employees. Six caves were entered more frequently by seropositive employees posing a potentially high risk. Several of these caves were in public use areas and were opened for tours. Education of area healthcare providers about TBRF and prevention recommendations for cavers and the public are advised.
