We used Google search data from January 1, 2014 to January 1, 2019 to explore public awareness of pre-exposure prophylaxis (PrEP) and HIV testing in the United States. Using two search strings, one for PrEP and one for HIV testing, we compared search volume to state HIV prevalence and new HIV diagnoses. We also used Google News to identify news events related to short-term spikes in search volume. Controlling for poverty, education, and internet access, a one-unit increase in a state's HIV prevalence rate was associated with a 3% increase in PrEP search volume (aPR = 1.03 [1.034, 1.037], P < 0.0001) and HIV testing search volume (aPR = 1.03 [1.030, 1.032], P < 0.0001). Short-term search volume spikes also coincided with celebrity news and pharmaceutical company advertising. We demonstrate that search engine data can be a powerful tool for understanding HIV knowledge-seeking and can provide key insight to the events that drive public interest about HIV online.
我们使用了 2014 年 1 月 1 日至 2019 年 1 月 1 日期间的谷歌搜索数据，以探讨美国公众对暴露前预防（PrEP）和 HIV 检测的认知。我们使用了两个搜索字符串，一个用于 PrEP，一个用于 HIV 检测，将搜索量与各州的 HIV 流行率和新的 HIV 诊断进行了比较。我们还使用谷歌新闻来识别与搜索量短期激增相关的新闻事件。在控制贫困、教育和互联网接入的情况下，一个州的 HIV 流行率每增加一个单位，PrEP 搜索量就会增加 3%（aPR=1.03[1.034,1.037]，P<0.0001），HIV 检测搜索量也会增加 3%（aPR=1.03[1.030,1.032]，P<0.0001）。短期搜索量的激增也与名人新闻和制药公司的广告有关。我们证明，搜索引擎数据可以成为了解 HIV 知识需求的有力工具，并为了解驱动公众对 HIV 在线兴趣的事件提供关键见解。
