Abstract

Objective: In order to master the epidemic trend of corona virus disease 2019 (COVID-19) and evaluate the effect of prevention and control, we evaluate the epidemic dynamics of COVID-19 in mainland China, Hubei province, Wuhan city and other provinces outside Hubei from January 16 to February 14, 2020. Methods: We collected the daily number of new confirmed COVID-19 cases by nucleic acid detection reported by the National Health Commission from January 16, 2020 to February 14, 2020. The analysis includes the epidemic curve of the new confirmed cases, multiple of the new confirmed cases for period-over-period, multiple of the new confirmed cases for fixed-base, and the period-over-period growth rate of the new confirmed cases. Results: From January 16 to February 14, 2020, the cumulative number of new confirmed cases of COVID-19 in mainland China was 50 031, including 37 930 in Hubei province, 22 883 in Wuhan city and 12 101 in other provinces outside Hubei. The peak of the number of new confirmed cases in other provinces outside Hubei was from January 31 to February 4, 2020, and the peak of new confirmed cases in Wuhan city and Hubei province was from February 5 to February 9, 2020. The number of new confirmed cases in other provinces outside Hubei showed a significant decline (23% compared with the peak) from February 5 to February 9, 2020, while the number of new confirmed cases in Wuhan city (30% compared with the peak) and Hubei Province (37% compared with the peak) decreased significantly from February 10 to February 14, 2020. Conclusion: The epidemic prevention and control measures taken by the state and governments at all levels have shown very significant effects, effectively curbing the spread of the COVID-19 epidemic in China.

<b>目的:</b>
为了掌握新型冠状病毒肺炎疫情的流行趋势和评价防控效果,本研究评估了2020年1月16日至2月14日中国内地、湖北省、武汉市以及湖北以外其他省份新型冠状病毒肺炎的流行动态变化。
<b>方法:</b>
选取2020年1月16日至2020年2月14日国家卫生健康委员会通报的每日新增经核酸检测确诊的新型冠状病毒肺炎病例数。分析新增确诊病例的流行曲线、环比新增确诊病例倍数、定基新增确诊病例倍数、环比新增确诊病例数增长率。
<b>结果:</b>
从2020年1月16日至2月14日,中国内地新冠病毒肺炎累计新增确诊病例数为50 031例,其中湖北省37 930例,武汉市22 883例,湖北以外其他各省12 101例。湖北以外其他各省新增确诊病例数高峰在2020年1月31日至2月4日,武汉市和湖北省的新增确诊病例数高峰在2020年2月5日至2月9日。湖北以外其他各省新增确诊病例数在2020年2月5日至2月9日呈现明显下降(与高峰时段相比下降了23%),而武汉市和湖北省的新增确诊病例数在2020年2月10日至2月14日明显下降(武汉下降了30%;湖北下降了37%)。
<b>结论:</b>
国家及各级政府采取的疫情防控措施已经呈现出非常显著的效果,有效地遏制了疫情在全中国的蔓延。.</AbstractText>
