Data from: The contemporary distribution of Trypanosoma cruzi infection in humans, alternative hosts and vectors

Chagas is a potentially fatal chronic disease affecting large numbers of people across the Americas and exported throughout the world through human population movement. It is caused by the Trypanosoma cruzi parasite, which is transmitted by triatomine vectors to humans and a wide range of alternative host species. The database described here was compiled to allow the risk of vectorial transmission to humans to be mapped using geospatial models. The database collates all available records, published since 2003, for prevalence and occurrence of infection in humans, vectors and alternative hosts, and links each record to a defined time and location. A total of 16,802 records of infection have been extracted from the published literature and unpublished sources. The resulting database can be used to improve our understanding of the geographic variation in vector infection prevalence and to estimate the risk of vectorial transmission of T. cruzi to humans.

查加斯病（Chagas disease）是一种潜在致命的慢性疾病，在美洲地区影响大量人群，并可通过人口流动向全球范围内扩散。该病由克氏锥虫（Trypanosoma cruzi）寄生虫引发，该寄生虫通过锥蝽（triatomine）媒介传播给人类以及多种潜在宿主物种。本文所述数据库的构建，旨在支持利用地理空间模型（geospatial models）绘制人类媒介传播（vectorial transmission）风险图谱。该数据库整合了2003年以来公开发表的所有可获取的人类、媒介及潜在宿主的感染患病率（prevalence）与感染发生记录，并将每条记录与明确的时间和空间位置关联。研究人员已从已发表文献与未公开资料中总计提取出16802条感染相关记录。所得数据库可用于深化我们对媒介感染患病率地理分布差异的认知，并估算克氏锥虫经媒介传播给人类的风险。
