Data on the topic of novel avian influenza A (H7N9) were collected based on the web analysis tool 'Baidu Index', a major Chinese search engine. We found a positive correlation between the volume of H7N9-related 'cyber user awareness' and the epidemic situation during the H7N9 outbreak in China (r=0.98, p<0.01, cumulative; r=0.43, p=0.018, daily) except in the early stage; the ranks of H7N9-related topics changed at different epidemic stages. This study may improve our understanding of the role of web-based media in infectious disease surveillance in China.
基于中国主要搜索引擎“百度指数”这一网络分析工具，收集了有关新型甲型H7N9禽流感的相关数据。我们发现，在中国H7N9疫情爆发期间，除了早期阶段，H7N9相关的“网络用户关注度”与疫情之间存在正相关关系（累积相关性：r = 0.98，p < 0.01；每日相关性：r = 0.43，p = 0.018）；H7N9相关话题的排名在不同疫情阶段有所变化。本研究可能会增进我们对网络媒体在中国传染病监测中所起作用的理解。
