Abstract：
OBJECTIVE: This study aims to understand a major result of ComCor, an online epidemiological study conducted to identify the circumstances of COVID-19 infection in France from 2020 to 2022: One third of respondents reported ignoring the circumstances of their infection.
METHODS: We conducted a qualitative study through semi-structured interviews, diagnosed in spring or summer 2021. Interviews were audio recorded, transcribed, and thematically analyzed.
RESULTS: Fifty interviews were conducted. Half of the participants in Qualicor were able to identify several at-risk situations, most often involving their entourage (family, friends, colleagues), but were uncertain as to which specific situation was the source of infection. Less than one quarter strongly suspected a specific situation without certainty, a similar proportion were unable to identify any circumstances, and only two people were certain about the origin of the infection. Several factors contributed to this lack of knowledge: a desire to conceal these circumstances (in a few rare cases), limitations of the questionnaire, lack of knowledge about how the virus is transmitted, selective perception of at-risk situations, co-existence of several possible sources of infection, and the difficulty of taking an objective view of certain circumstances of transmission.
CONCLUSIONS: Our study shows the benefits of a mixed approach designed to better understand the perception of Covid 19 contamination circumstances in the French population. It also highlights the need to strengthen or improve communication on modes of virus transmission, especially airborne transmission, and the importance of maintaining certain preventive behaviors after vaccination.

摘要：
目的：本研究旨在了解ComCor的主要结果，一项旨在确定2020年至2022年法国COVID-19感染情况的在线流行病学研究:三分之一的受访者报告称忽略了其感染情况.
方法：我们通过半结构化访谈进行了定性研究，在2021年春季或夏季诊断。采访是录音，转录，并进行了主题分析。
结果：进行了50次访谈。Qualicor的一半参与者能够识别出几种有风险的情况，最经常涉及他们的随行人员(家庭，朋友,同事)，但不确定哪种具体情况是感染源。不到四分之一的人强烈怀疑具体情况没有确定，类似比例的人无法识别任何情况，只有两个人确定感染的起源。有几个因素导致了这种知识的缺乏：隐藏这些情况的愿望（在少数罕见的情况下），问卷的局限性，缺乏关于病毒是如何传播的知识，对危险情况的选择性感知，几种可能的感染源共存，以及难以客观地看待某些传播情况。
结论：我们的研究表明，采用混合方法旨在更好地了解法国人群对新冠肺炎污染情况的看法。它还强调需要加强或改善有关病毒传播模式的沟通，尤其是机载传输，以及疫苗接种后保持某些预防行为的重要性。
