基于互联网的监测系统提供了一种监测传染病的新方法。基于互联网数据的监控系统在经济、后勤和流行病学方面都具有吸引力，并且已显示出巨大的前景。随着互联网可用性的增加和健康相关信息搜索行为的转变，这些系统的潜力也随之增加。然而，这种监测传染病的方法仅适用于单一或一小群选定的疾病。本研究旨在系统地研究利用互联网搜索数据开发针对多种传染病的监测和预警系统的潜力。下载了澳大利亚 64 种传染病的官方通知，并使用 Spearman 排名相关性将 2009-13 年期间 164 个互联网搜索词的频率关联起来。进行时间序列互相关来评估搜索词用于构建预警系统的潜力。 17 种传染病 (26.6%) 的通知被发现与选定的搜索词显着相关。此前尚未对其中 12 种 (70.6%) 疾病使用互联网指标作为监测手段进行描述。大多数已确定的疾病是可以通过疫苗预防、媒介传播或性传播的疾病；然而，相互关系表明，媒介传播疾病和疫苗可预防疾病最适合开发预警系统。这项研究的结果表明，基于互联网的监测系统在监测传染病方面具有比以前认识到的更广泛的适用性。此外，基于互联网的监测系统在预测新出现的传染病事件方面具有潜在作用，特别是对于疫苗可预防的疾病和媒介传播的疾病。本文的在线版本 (doi:10.1186/s12879-014-0690-1) 包含补充材料，可供授权用户使用。
Internet-based surveillance systems provide a novel approach to monitoring infectious diseases. Surveillance systems built on internet data are economically, logistically and epidemiologically appealing and have shown significant promise. The potential for these systems has increased with increased internet availability and shifts in health-related information seeking behaviour. This approach to monitoring infectious diseases has, however, only been applied to single or small groups of select diseases. This study aims to systematically investigate the potential for developing surveillance and early warning systems using internet search data, for a wide range of infectious diseases. Official notifications for 64 infectious diseases in Australia were downloaded and correlated with frequencies for 164 internet search terms for the period 2009–13 using Spearman’s rank correlations. Time series cross correlations were performed to assess the potential for search terms to be used in construction of early warning systems. Notifications for 17 infectious diseases (26.6%) were found to be significantly correlated with a selected search term. The use of internet metrics as a means of surveillance has not previously been described for 12 (70.6%) of these diseases. The majority of diseases identified were vaccine-preventable, vector-borne or sexually transmissible; cross correlations, however, indicated that vector-borne and vaccine preventable diseases are best suited for development of early warning systems. The findings of this study suggest that internet-based surveillance systems have broader applicability to monitoring infectious diseases than has previously been recognised. Furthermore, internet-based surveillance systems have a potential role in forecasting emerging infectious disease events, especially for vaccine-preventable and vector-borne diseases.
