莱姆病是由伯格多弗疏螺旋体(Borrelia burgdorferi)引起的,受感染的硬蜱(欧洲为蓖子硬蜱)通过叮咬把病原体传播给人体。中欧携带伯格多弗螺旋体的硬蜱比例较高(30%),而发病率相对较低约2%～4%。也就是说,不是每个接触硬蜱的人都感染,感染上也不一定发病。莱姆病的临床表现累及不同的器官。病程分 Lyme disease is caused by Borrelia burgdorferi, an infected tick, which in Europe transmits its pathogen to humans through bites. Central European countries have a higher proportion of hard-ticks with Bordetella burgdorferi (30%), while the incidence is relatively low at about 2% to 4%. In other words, not every person who is affected by ticks is infected, and the infection is not necessarily affected. The clinical manifestations of Lyme disease involve different organs.
