Relapsing fever is caused by the Borrelia species of spirochetes. Louse-born epidemics of the disease may occur but the endemic disease is usually transmitted to humans by the bite of an infected tick (Ornithodorus). Transplacental infection was suggested more than 75 years ago (1) but has been rarely documented (2). We describe a case of neonatal relapsing fever where maternal infection was the probable cause of the premature delivery and infection in the infant.
回归热由疏螺旋体属的疏螺旋体引起。该病可发生虱传流行，但地方性疾病通常通过受感染蜱（钝缘蜱属）叮咬传播给人类。75多年前就有人提出经胎盘感染（1），但鲜有文献记载（2）。我们描述了一例新生儿回归热病例，其中母亲感染可能是婴儿早产和感染的原因。
