自2009年4月下旬以来，一种通常被称为“猪流感”的新型流感病毒a （H1N1）在全球蔓延，感染了数十万人。在墨西哥首次暴发后的最初几天，媒体的广泛报道以及与该病毒有关的传播性和死亡率的高度不确定性引起了人们的广泛关注。在流行病的早期阶段，行为变化（例如保持社会距离）可能对传染病的传播产生强烈影响，但关于风险认知和对新型病毒的行为反应的数据通常是在相当长的时间内或在流行病结束后收集的。在此，我们报告了一项在线调查的结果，该调查收集了在媒体广泛报道的最初几天（2009年4月28日至5月5日）对甲型H1N1流感爆发的风险认知的数据（n = 6249）。我们发现，在最初的高度关注之后，随着人们将病毒视为迫在眉睫的威胁，焦虑程度逐渐减弱。总的来说，我们的数据提供了情绪状态调节行为反应的证据。有趣的是，主成分分析显示，人们对猪流感、禽流感和恐怖主义的焦虑有很强的聚集性。这三种威胁都受到了媒体的大量关注，它们根本的不确定性可能会导致人们对它们的实际威胁产生过度的恐惧。我们的研究结果表明，受访者的行为以可预测的方式变化。特别有趣的是，我们发现情感变量，如自我报告的对疫情的焦虑，调节了受访者采取保护行为的可能性。了解诸如社交距离之类的保护行为是如何变化的，以及调节这种变化的具体因素，可能有助于设计流行病控制策略。
Since late April, 2009, a novel influenza virus A (H1N1), generally referred to as the “swine flu,” has spread around the globe and infected hundreds of thousands of people. During the first few days after the initial outbreak in Mexico, extensive media coverage together with a high degree of uncertainty about the transmissibility and mortality rate associated with the virus caused widespread concern in the population. The spread of an infectious disease can be strongly influenced by behavioral changes (e.g., social distancing) during the early phase of an epidemic, but data on risk perception and behavioral response to a novel virus is usually collected with a substantial delay or after an epidemic has run its course. Here, we report the results from an online survey that gathered data (n = 6,249) about risk perception of the Influenza A(H1N1) outbreak during the first few days of widespread media coverage (April 28 - May 5, 2009). We find that after an initially high level of concern, levels of anxiety waned along with the perception of the virus as an immediate threat. Overall, our data provide evidence that emotional status mediates behavioral response. Intriguingly, principal component analysis revealed strong clustering of anxiety about swine flu, bird flu and terrorism. All three of these threats receive a great deal of media attention and their fundamental uncertainty is likely to generate an inordinate amount of fear vis-a-vis their actual threat. Our results suggest that respondents' behavior varies in predictable ways. Of particular interest, we find that affective variables, such as self-reported anxiety over the epidemic, mediate the likelihood that respondents will engage in protective behavior. Understanding how protective behavior such as social distancing varies and the specific factors that mediate it may help with the design of epidemic control strategies.
