Abstract:
COVID-19 has caused more than 600 million cases， more than 6 million death and mortality of 1.24% worldwide. One out of every six people caught COVID-19 at the 5th wave of expansion， having a mortality of 15 per 10 thousand. China mainland with the dynamic zero-COVID-19 strategy have decreased 699 million cases and 6.26 million deaths from dynamic zero-COVID-19 strategy in 3 years in case of yearly outbreak of COVID-19， according to the situation of Omicron variant in Hongkong with incidence of one out of every six people and 0.76% of mortality. With the stronger contagious and variation of the virus， there is less long-term latency. The Chinese governments have more efficient control of epidemic of dynamic zero-COVID-19 strategy caused by imported cases with local diffusion by physical separation and isolation as measure of quarantines； have quick and effective results with zero new cases， which kept the health and safety for people in China. The paper analyzes the efficient measures and achievement of dynamic zero-COVID-19 strategy in Beihai and Chongzuo of Guangxi under the outbreaks of COVID-19 Omicron variant on July of 2022， after the calculation of expanding latency as ≤4 days， ≤7 days or ≥ 8 days’ different latency of primary strains， of expanding latency of Delta variant in part of cases in Yangzhou City of Jiangsu， and of expanding latency of Omicron coming out from chain-expanding cases from Xiaojinge clothing store of Beijing.
