登革热是一种蚊子传播的疾病,威胁着世界上一半以上的人口。尽管在100多个国家流行,但在许多受影响地区仍然缺乏政府主导的及时识别和跟踪新感染的努力和工具。已经提出了利用基于互联网的数据源的多种方法,作为补充登革热监测工作的一种方式。其中,与登革热相关的谷歌搜索趋势已被证明与登革热活动相关。我们扩展了一个方法框架,最初提出并验证了流感监测,产生近实时估计登革热病例在五个国家/地区:墨西哥,巴西,泰国,新加坡和台湾。我们的研究结果表明,我们的建模框架可以用于改善世界各地登革热活动的跟踪。随着传染病在我们的社会中蔓延,人们经常转向互联网搜索医疗信息。近年来,多个研究团队研究了如何利用互联网用户的搜索活动来跟踪我们星球上的传染病。在这篇文章中,我们展示了一种最初用于跟踪美国流感的方法,可以扩展到过去几年中观察到登革热的多个国家/州,以改善登革热监测。我们的研究结果表明,我们的方法在登革热流行地区表现最好,每年有大量的病例和持续的季节性发病率。
Dengue is a mosquito-borne disease that threatens over half of the world’s population. Despite being endemic to more than 100 countries, government-led efforts and tools for timely identification and tracking of new infections are still lacking in many affected areas. Multiple methodologies that leverage the use of Internet-based data sources have been proposed as a way to complement dengue surveillance efforts. Among these, dengue-related Google search trends have been shown to correlate with dengue activity. We extend a methodological framework, initially proposed and validated for flu surveillance, to produce near real-time estimates of dengue cases in five countries/states: Mexico, Brazil, Thailand, Singapore and Taiwan. Our result shows that our modeling framework can be used to improve the tracking of dengue activity in multiple locations around the world. As communicable diseases spread in our societies, people frequently turn to the Internet to search for medical information. In recent years, multiple research teams have investigated how to utilize Internet users’ search activity to track infectious diseases around our planet. In this article, we show that a methodology, originally developed to track flu in the US, can be extended to improve dengue surveillance in multiple countries/states where dengue has been observed in the last several years. Our result suggests that our methodology performs best in dengue-endemic areas with high number of yearly cases and with sustained seasonal incidence.
