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.
