Abstract

The common bed bug (Cimex lectularius L.) is once again prevalent in the United States. We investigated temporal patterns in Google search queries for bed bugs and co-occurring terms, and conducted in-person surveys to explore the intentions behind searches that included those terms. Searches for "bed bugs" rose steadily through 2011 and then plateaued, suggesting that the epidemic has reached an equilibrium in the United States. However, queries including terms that survey respondents associated strongly with having bed bugs (e.g., "exterminator," "remedies") continued to climb, while terms more closely associated with informational searches (e.g., "hotels," "about") fell. Respondents' rankings of terms and nonseasonal trends in Google search volume as assessed by a cosinor model were significantly correlated (Kendall's Tau-b P = 0.015). We find no evidence from Google Trends that the bed bug epidemic in the United States has reached equilibrium.

摘要

普通臭虫（温带臭虫）在美国再度盛行。我们调查了谷歌上臭虫及相关词汇搜索查询的时间模式，并进行了实地调查，以探究包含这些词汇的搜索背后的意图。“臭虫”的搜索量在2011年之前稳步上升，之后趋于平稳，这表明在美国臭虫疫情已达到平衡状态。然而，包含调查对象强烈关联有臭虫的词汇（如“灭虫员”“补救措施”）的查询持续攀升，而与信息搜索关联更紧密的词汇（如“酒店”“关于”）则下降。通过余弦模型评估，调查对象对词汇的排名与谷歌搜索量的非季节性趋势显著相关（肯德尔tau-b检验，P = 0.015）。我们从谷歌趋势中没有发现美国臭虫疫情已达到平衡的证据。
