Abstract

Ticks are an increasingly important threat to public health in Southeast Asia, due to the role of many tick species as parasites of humans and as vectors of zoonotic pathogens. Singapore is a densely populated Southeast Asian nation with a rich tick fauna and a significant mosaic of city and greenspace. However, apart from occasional case reports, the human-biting ticks in Singapore have received little attention from researchers. Based on an ongoing nationwide tick surveillance program beginning in 2018 and literature records (since 2002), we present data from 51 cases of tick infestation in humans in Singapore involving 128 individual ticks of 11 species. The genera Dermacentor, Haemaphysalis, Ixodes, and Amblyomma were all found to bite humans in Singapore. The most common species infesting humans in Singapore was Dermacentor auratus which was responsible for more than half of all infestations. The first records of Haemaphysalis papuana in Singapore are also presented, with 3 cases of human infestation by this tick species. Finally, we highlight the Singapore National Tick Reference Collection (SNTRC) as an invaluable resource for the identification and study of ticks in Singapore.

新加坡全国范围内蜱类（蜱螨：伊蚊科）感染人类的监测。

由于许多蜱类作为人类寄生虫和人畜共患病原体的媒介，蜱对东南亚的公共卫生构成了日益重要的威胁。新加坡是一个人口稠密的东南亚国家，拥有丰富的蜱类动物，城市和绿地的马赛克效果显著。然而，除了偶尔的病例报告外，新加坡的咬人蜱很少受到研究人员的关注。根据2018年开始的全国性蜱虫监测计划和文献记录（自2002年以来），我们提供了新加坡51例人类蜱虫感染病例的数据，涉及11种128只蜱虫。在新加坡，发现有皮肤螨属、血蜱属、硬蜱属和弱视虫属咬人。在新加坡，最常见的人类害虫是auratus，占所有害虫的一半以上。本文还介绍了新加坡巴布亚血蜱的首次记录，其中有3例人类感染该蜱虫。最后，我们强调了新加坡国家蜱参考馆藏（SNTRC）作为鉴定和研究新加坡蜱的宝贵资源。

期刊介绍： Ticks and Tick-borne Diseases is an international, peer-reviewed scientific journal. It publishes original research papers, short communications, state-of-the-art mini-reviews, letters to the editor, clinical-case studies, announcements of pertinent international meetings, and editorials. The journal covers a broad spectrum and brings together various disciplines, for example, zoology, microbiology, molecular biology, genetics, mathematical modelling, veterinary and human medicine. Multidisciplinary approaches and the use of conventional and novel methods/methodologies (in the field and in the laboratory) are crucial for deeper understanding of the natural processes and human behaviour/activities that result in human or animal diseases and in economic effects of ticks and tick-borne pathogens. Such understanding is essential for management of tick populations and tick-borne diseases in an effective and environmentally acceptable manner.
