Tick-borne flaviviruses and spp. are globally spread pathogens of zoonotic potential that are maintained by a transmission cycle at the interface between ticks and vertebrate hosts, mainly wild animals. Aside data on pathogen burden in ticks, information on the status of various hosts relative to infection is important to acquire. We reviewed how those infections have been studied in wildlife host species in the field to discuss how collected data provided relevant epidemiological information and to identify needs for further studies. The literature was screened for observational studies on pathogen or antibody detection for tick-borne spp. and flaviviruses in wildlife host animals. Overall, spp. were more studied (73% of case studies, representing 297 host species) than flaviviruses (27% of case studies, representing 114 host species). Studies on both spp. and flaviviruses focused mainly on the same species, namely bank vole and yellow-necked mouse. Most studies were order-specific and cross-sectional, reporting prevalence at various locations, but with little insight into the underlying epidemiological dynamics. Host species with potential to act as reservoir hosts of these pathogens were neglected, notably birds. We highlight the necessity of collecting both demographics and infection data in wildlife studies, and to consider communities of species, to better estimate zoonotic risk potential in the One Health context.
蜱传黄病毒和[未提及的病原体名称]是具有全球传播潜力的人畜共患病原体，通过蜱与脊椎动物宿主（主要是野生动物）之间的传播循环得以维持。除了蜱中病原体负荷的数据外，获取有关各种宿主感染状况的信息也很重要。我们回顾了如何在野外对野生动物宿主物种中的这些感染进行研究，以讨论所收集的数据如何提供相关的流行病学信息，并确定进一步研究的需求。对文献进行筛选，以查找关于野生动物宿主动物中蜱传[未提及的病原体名称]和黄病毒的病原体或抗体检测的观察性研究。总体而言，对[未提及的病原体名称]的研究（占案例研究的73%，涉及297种宿主物种）比对黄病毒的研究（占案例研究的27%，涉及114种宿主物种）更多。对[未提及的病原体名称]和黄病毒的研究主要集中在相同的物种上，即棕背田鼠和黄颈姬鼠。大多数研究是特定目且横断面的，报告了不同地点的患病率，但对潜在的流行病学动态了解甚少。有潜力作为这些病原体储存宿主的宿主物种被忽视了，特别是鸟类。我们强调在野生动物研究中收集人口统计学和感染数据以及考虑物种群落的必要性，以便在“同一个健康”背景下更好地估计人畜共患病风险潜力。
