Molecular epidemiology of trypanosomes for evidence-based tsetse-vector control

The data file are findings from a study to understand trypanosome epidemiology and evaluate the tsetse-vector control in a Kenya sylvatic ecology. The file is comprised of six sub-sets. The first sub-set reports observations made in laboratory analysis of trypanosome infection in tsetse flies, and the vertebrate hosts of tsetse flies and likely sources of infection. In the same sub-set, data are presented on the wing length (a proxy for body size), chronological age (assessed by the wing fray scoring technique), species type, sex, and collection date and site of each of 696 tsetse flies. The second sub-set is a detailed result of reports from bimonthly entomological field surveillance of tsetse flies carried out in Shimba Hills (Kenya). Parasitological surveys of trypanosome in cattle populations were implemented at some points during the entomological survey in Shimba Hills with findings from the survey of cattle shown in the third data sub-set. Data sub-sets four through six describe the observations made in a cluster randomised controlled trial (RCT) in an intervention to control trypanosome tsetse-vectors in Shimba Hills respectively using As-treated analysis, Intention-To-Treat and Per-Protocol analysis techniques. In the cluster RCT, dispensers of a blend of tsetse-repellent waterbuck-mimicking synthetic volatiles (denoted as WBR in the dataset) were deployed alongside tsetse-attractive insecticide-treated fabrics (ITF) in the intervention arm and without these fabrics in the control arm. The columns bTcTv, bTc and bTv are used to denote cattle infection at baseline before intervention.

本数据集源自一项旨在探究锥虫（Trypanosoma）流行病学、评估肯尼亚林栖生态系统中采采蝇（tsetse fly）媒介防控效果的研究成果，共包含6个子数据集。
第一个子数据集收录了针对采采蝇、采采蝇脊椎动物宿主的锥虫感染情况，以及潜在感染源开展实验室分析所得的观测数据；同时收录了696只采采蝇的翅长（作为体型的替代指标）、经翅磨损评分法评估的实际年龄、物种类型、性别、采集日期与采集地点等信息。
第二个子数据集为肯尼亚希姆巴丘陵（Shimba Hills）地区采采蝇双月昆虫学野外监测的详细报告结果。
在希姆巴丘陵的昆虫学监测期间，研究团队于多个节点开展了牛群锥虫寄生虫学调查，相关调查结果收录于第三个子数据集中。
第四至第六个子数据集分别对应在希姆巴丘陵开展的采采蝇媒介防控整群随机对照试验（cluster randomised controlled trial, RCT）的观测数据，其分析方法依次为实际治疗分析（As-treated analysis）、意向性治疗分析（Intention-To-Treat）与符合方案分析（Per-Protocol）。
在本整群随机对照试验中，干预组部署了搭载采采蝇驱避型仿水羚合成挥发性混合物（本数据集中记为WBR）的散发装置，并搭配采采蝇引诱型杀虫剂处理织物（insecticide-treated fabrics, ITF）；对照组则仅部署该散发装置，未搭配杀虫剂处理织物。
数据列bTcTv、bTc与bTv分别用于表示干预前基线状态下的牛群感染情况。
