Pandemic management is likely to represent a global reality for years to come, but the roadmap for how to approach pandemic restrictions is as yet unclear. Of the restrictions enacted during COVID-19, among the more controversial surround alcohol. Like many infectious diseases, the principal mode of transmission for COVID-19 is direct respiration of droplets emitted during close social contact, and health officials warn that alcohol consumption may lead to decreased adherence to physical distancing guidelines. Governing bodies have acted to close bars before restaurants and have also specifically restricted alcohol sales, while at the same time those in the nightlife industry have labeled such actions unfounded and discriminatory. Complicating such debates is the lack of evidence on alcohol’s effects on physical distance. In the current study we employed a randomized alcohol-administration design paired with computer-vision measures, analyzing over 20,000 proximity readings derived from video to examine the effect of alcohol consumption on physical distance during social interaction. Results indicated that alcohol caused individuals to draw significantly closer to an unfamiliar interaction partner during social exchange, reducing physical proximity at a rate with potentially important implications for public health. In contrast, alcohol had no effect on physical distance with a familiar interaction partner. Findings suggest that alcohol might act to overcome a natural caution people feel towards strangers and thus promote virus transmission between previously unconnected social groups.

酒精缩小陌生人之间的身体距离[药理学]

大流行管理可能代表未来几年的全球现实,但如何处理大流行限制的路线图尚不清楚。在 COVID-19 期间制定的限制措施中,最有争议的围绕酒精。与许多传染病一样,COVID-19 的主要传播方式是直接呼吸在密切社会接触期间释放的飞沫,卫生官员警告说,饮酒可能会导致对身体距离准则的遵守程度降低。管理机构已采取行动,在餐馆之前关闭酒吧,并特别限制酒类销售,而与此同时,夜生活行业的人则将此类行为标记为没有根据和歧视性。使此类辩论复杂化的是缺乏关于酒精对身体距离影响的证据。在当前的研究中,我们采用了与计算机视觉测量相结合的随机饮酒设计,分析了来自视频的 20,000 多个邻近读数,以检查饮酒对社交互动过程中物理距离的影响。结果表明,酒精会导致个人在社交交流过程中与不熟悉的互动伙伴更加接近,从而以可能对公共健康产生重要影响的速度减少身体接触。相比之下,酒精对与熟悉的互动伙伴的物理距离没有影响。研究结果表明,酒精可能会起到克服人们对陌生人的自然警告的作用,从而促进病毒在以前没有联系的社会群体之间的传播。
