Google Trends is an online tool that allows measurement of search term popularity on Google, spatially and temporally. While not an epidemiological tool for determining incidence, it can estimate the popularity of a certain disease by search volume over time. It has previously correlated well with infectious disease incidence and has demonstrated utility in disease forecasting, especially with influenza data. We utilized Google Trends to investigate whether search interest in common gastrointestinal (GI) symptoms would correlate with coronavirus disease 2019 (COVID-19) incidence data.
谷歌趋势(Google Trends)是一种在线工具,可在空间和时间上衡量谷歌搜索词的流行度。虽然它不是用于确定发病率的流行病学工具,但可以通过随时间推移的搜索量来估计某种疾病的流行程度。它以前与传染病发病率相关性较好,并已证明在疾病预测方面具有实用性,尤其是在流感数据方面。我们利用谷歌趋势(Google Trends)来研究胃肠道(GI)常见症状的搜索量是否与 2019 冠状病毒病(COVID-19)发病率数据相关。
