新型冠状病毒肺炎的原发病例及其发生发展证据

Primary Case of COVID-19 and Its Occurrence and Development Evidence

原发病例,俗称"零号病人",指疫情扩散时被病毒或细菌性疾病感染的第一人,往往因他造成了大规模的传染病暴发。对"零号病人"的流行病学追溯,以及发生、发展过程的溯源,有助于对感染病原的深入了解和认识,对于传染源的控制,疾病的预防有着十分重要的意义。本研究从新冠肺炎的首诊病例的确认、最早的爆发时间点分析以及发生发展的时间线的梳理,初步还原了新冠肺炎(COVID-19)从发现到爆发的过程,对深度认识新冠病毒(SARS-CoV-2)和新冠肺炎(COVID-19)有着重要的参考价值。

Primary case,commonly known as"No.0 patient",refers to the first person who is infected by a virus or bacterial disease when the epidemic situation spreads."No.0 patient"often causes a large-scale outbreak of infectious diseases.Tracing the epidemiology of"No.0 patient"and the origin of the occurrence and development are helpful to make clear and understand the pathogen of infection.It is of great significance to control the source of infection and prevent the disease.In this study,from the confirmation of the first diagnosis case of COVID-19,the analysis of the earliest outbreak time point and the carding of the occurrence and development time line of COVID-19,the process from discovery to outbreak of COVID-19 is preliminarily restored,which has important reference value for further understanding of SARS-CoV-2 and COVID-19.
