项目摘要

DESCRIPTION (provided by applicant): In this work we will develop and field validate "FeverPhone" technology for point-of-care differential diagnosis of six common causes of acute febrile illness (namely: Dengue, Malaria, Chikungunya, Leptospirosis, Typhoid fever, and Chagas). The "FeverPhone" system builds on our team's extensive background on the development of smartphone based diagnostics, infectious disease, and global health. The technical effort of this program comprises of the development of: a specialized 6-plexed colorimetric IgM/IgG assay cartridge that exploits our previous work on color discrimination assays on mobile devices, associated iPad based hardware that allows rapid interpretation of the cartridge results on a platform already used by our field technicians, and software that will combine differential molecular diagnosis with a confirmatory symptomatic interface used by the operator. The final system will enable actionable diagnosis in around 15 minutes. In parallel with technical development, we will perform a staged field validation study at our existing infectious diseases monitoring site in Machala, Ecuador. In addition to clinical and engineering expertise, we have incorporated a translation partner into the program that will ensure that our system is fully validated and ready for FDA approval by the end of the effort.

描述（由申请人提供）：在这项工作中，我们将开发和现场验证“FeverPhone”技术，用于急性发热性疾病的六种常见原因（即：登革热、疟疾、基孔肯雅热、钩端螺旋体病、伤寒和恰加斯病）的即时鉴别诊断。“FeverPhone”系统建立在我们团队在智能手机诊断、传染病和全球健康开发方面的广泛背景之上。该计划的技术工作包括开发：一种专门的6路比色IgM/IgG检测盒，其利用了我们先前在移动的设备上的颜色辨别检测方面的工作，相关的基于iPad的硬件允许在我们的现场技术人员已经使用的平台上快速解释检测盒结果，以及将联合收割机鉴别分子诊断与操作者使用的确认症状界面相结合的软件。最终系统将在大约15分钟内实现可操作的诊断。在技术开发的同时，我们将在厄瓜多尔Machala现有的传染病监测点进行阶段性现场验证研究。除了临床和工程专业知识外，我们还将翻译合作伙伴纳入该计划，以确保我们的系统经过充分验证，并在工作结束时准备好获得FDA批准。
