Capture of surveillance data on mobile devices and rapid transfer of such data from these devices into an electronic database or data management and decision support systems promote timely data analyses and public health response during disease outbreaks. Mobile data capture is used increasingly for malaria surveillance and holds great promise for surveillance of other neglected tropical diseases. We focused on mosquito-borne dengue, with the primary aims of: 1) developing and field-testing a cell phone-based system (called Chaak) for capture of data relating to the surveillance of the mosquito immature stages, and 2) assessing, in the dengue endemic setting of Mérida, Mexico, the cost-effectiveness of this new technology versus paper-based data collection. Chaak includes a desktop component, where a manager selects premises to be surveyed for mosquito immatures, and a cell phone component, where the surveyor receives the assigned tasks and captures the data. Data collected on the cell phone can be transferred to a central database through different modes of transmission, including near-real time where data are transferred immediately (e.g., over the Internet) or by first storing data on the cell phone for future transmission. Spatial data are handled in a novel, semantically driven, geographic information system. Compared with a pen-and-paper-based method, use of Chaak improved the accuracy and increased the speed of data transcription into an electronic database. The cost-effectiveness of using the Chaak system will depend largely on the up-front cost of purchasing cell phones and the recurring cost of data transfer over a cellular network.
利用移动设备采集监测数据，并将这些数据迅速传入电子数据库或数据管理和决策支持系统，有助于在疾病暴发期间及时进行数据分析和公共卫生应对。移动数据采集越来越多地用于疟疾监测，对于监测其他被忽视的热带病也具有巨大潜力。我们专注于蚊媒登革热，主要目的是：1）开发并实地测试一种基于手机的系统（称为 Chaak），用于采集与监测蚊虫幼虫阶段相关的数据，2）在墨西哥梅里达的登革热流行地区，评估这种新技术与基于纸张的数据收集相比的成本效益。Chaak 包括一个桌面组件，其中管理员选择要进行蚊虫幼虫调查的场所，以及一个手机组件，调查员在该组件中接收指定任务并采集数据。手机上采集的数据可以通过不同的传输模式传输到中央数据库，包括实时传输（例如通过互联网）或首先在手机上存储数据以备将来传输。空间数据采用新颖的、语义驱动的地理信息系统进行处理。与纸笔方法相比，使用 Chaak 提高了数据转录为电子数据库的准确性和速度。使用 Chaak 系统的成本效益在很大程度上取决于购买手机的前期成本和通过蜂窝网络进行数据传输的经常性成本。
