The severe acute respiratory syndrome–coronavirus-2 pandemic has spread rapidly and has a growing impact on individuals, communities, and healthcare systems worldwide. At the core of any pandemic response is the ability of authorities and other stakeholders to react appropriately by promoting hygiene and social distancing behaviors. Successfully reaching this goal requires both individual and collective efforts to drastically modify daily routines and activities. There is a need to clarify how knowledge and awareness of disease influence risk perception, and subsequent behavior in the context of pandemics and global outbreaks. We conducted a scoping review of 149 studies spanning different regions and populations to examine the relationships between knowledge, risk perceptions, and behavior change. We analyzed studies on five major pandemics or outbreaks in the twenty-first century: severe acute respiratory syndrome, influenza A/H1N1, Middle East respiratory syndrome, Ebola virus disease, and coronavirus disease 2019.

严重的急性呼吸综合症–冠状病毒2大流行已迅速蔓延，并且对全世界的个人，社区和医疗系统产生越来越大的影响。大流行应对措施的核心是当局和其他利益相关者通过促进卫生和社会疏远行为做出适当反应的能力。成功实现这一目标需要个人和集体共同努力，以彻底改变日常工作和活动。有必要弄清楚疾病的知识和意识如何影响风险感知以及大流行和全球爆发情况下的后续行为。我们对涵盖不同地区和人群的149项研究进行了范围界定研究，以检查知识，风险感知和行为改变之间的关系。
