Ticks are the second most important vectors of infectious diseases after mosquitoes worldwide. The growth of international tourism including in rural and remote places increasingly exposes travelers to tick bite. Our aim was to review the main tick-borne infectious diseases reported in travelers in the past 5 years.
In recent years, tick-borne bacterial diseases have emerged in travelers including spotted fever group (SFG) rickettsioses, borrelioses, and diseases caused by bacteria of the Anaplasmataceae family. African tick-bite fever, due to Rickettsia africae, is the most frequent agent reported in travelers returned from Sub-Saharan areas. Other SFG agents are increasingly reported in travelers, and clinicians should be aware of them. Lyme disease can be misdiagnosed in Southern countries. Organisms causing tick-borne relapsing fever are neglected pathogens worldwide, and reports in travelers have allowed the description of new species. Infections due to Anaplasmataceae bacteria are more rarely described in travelers, but a new species of Neoehrlichia has recently been detected in a traveler. The treatment of these infections relies on doxycycline, and travelers should be informed before the trip about prevention measures against tick bites.
蜱是全球仅次于蚊子的第二重要传染病传播媒介。包括农村和偏远地区在内的国际旅游业的发展，使旅行者越来越容易受到蜱叮咬。我们的目的是回顾过去5年旅行者中报告的主要蜱传传染病。
近年来，旅行者中出现了蜱传细菌疾病，包括斑点热群立克次体病、莱姆病以及无形体科细菌引起的疾病。由非洲立克次体引起的非洲蜱咬热是从撒哈拉以南地区返回的旅行者中报告最多的病原体。其他斑点热群病原体在旅行者中的报告越来越多，临床医生应予以关注。在南方国家，莱姆病可能会被误诊。引起蜱传回归热的病原体是全球被忽视的病原体，旅行者中的报告有助于描述新物种。无形体科细菌感染在旅行者中的描述较少，但最近在一名旅行者中检测到一种新的新埃立克体物种。这些感染的治疗依赖于强力霉素，旅行者在旅行前应被告知预防蜱叮咬的措施。
