摘要
What is already known about this topic?COVID-19 has a high transmissibility calculated by mathematical model.The dynamics of the disease and the effectiveness of intervention to control the transmission remain unclear in Jilin Province,China.What is added by this report?This is the first study to report the dynamic characteristics and to quantify the effectiveness of interventions implemented in the second outbreak of COVID-19 in Jilin Province,China.The effective reproduction number of the disease before and after May 10 was 4.00 and p<0.01,respectively.The combined interventions reduced the transmissibility of COVID-19 by 99% and the number of cases by 98.36%.What are the implications for public health practice?The findings of this study would add data on the transmission of COVID-19 and provide evidence to prepare the second outbreak transmission of the disease in other areas of China even in many other countries.
