封锁前武汉COVID-19爆发的发生率和影响评估

Evaluating Incidence and Impact Estimates of the COVID-19 Outbreak from Wuhan before Lockdown

Mai He, Li Li, Louis P. Dehner

摘要:

背景:中国武汉是COVID-19疫情的中心。本研究的目的是在采取干预措施之前了解感染传播动力学。方法:通过pubmed和互联网检索资料和关键事件。使用从各种数据源中提取的数据计算流行病学数据。结果如下:我们建立了一个时间轴,显示到2020年1月1日,中国当局已获得令人信服的人传人证据;然而,直到2020年1月20日,这些信息才与公众分享。我们的研究估计,如果在2020年1月2日采取干预措施,总共将有10989例感染病例,而在2020年1月23日实施封锁时则有239875例。结论:中国隐瞒有关2020年COVID-19疫情的关键信息及其延迟反应,最终导致本世纪最大的公共卫生危机,如果采取早期对策,本可以避免。

英文摘要:

Background: Wuhan, China was the epicenter of COVID-19 pandemic. The goal of current study is to understand the infection transmission dynamics before intervention measures were taken. Methods: Data and key events were searched through pubmed and internet. Epidemiological data were calculated using data extracted from a variety of data sources. Results: We established a timeline showing by January 1, 2020, Chinese authorities had been presented convincing evidence of human-to-human transmission; however, it was not until January 20, 2020 that this information was shared with the public. Our study estimated that there would have been 10989 total infected cases if interventions were taken on January 2, 2020, versus 239875 cases when lockdown was put in place on January 23, 2020. Conclusions: China's withholding of key information about the 2020 COVID-19 outbreak and its delayed response ultimately led to the largest public health crisis of this century and could have been avoided with earlier countermeasures.
