The COVID-19 pandemic is still ongoing in the world, the risk of COVID-19 spread from other countries or in the country will exist for a long term in China. In the routine prevention and control phase, a number of local COVID-19 epidemics have occurred in China, most COVID-19 cases were sporadic ones, but a few case clusters or outbreaks were reported. Winter and spring were the seasons with high incidences of the epidemics; border and port cities had higher risk for outbreaks. Active surveillance in key populations was an effective way for the early detection of the epidemics. Through a series of comprehensive prevention and control measures, including mass nucleic acid screening, close contact tracing and isolation, classified management of areas and groups at risk, wider social distancing and strict travel management, the local COVID-19 epidemics have been quickly and effectively controlled. The experiences obtained in the control of the local epidemics would benefit the routine prevention and control of COVID-19 in China. The occurrence of a series of COVID-19 case clusters or outbreaks has revealed the weakness or deficiencies in the COVID-19 prevention and control in China, so this paper suggests some measures for the improvement of the future prevention and control of COVID-19.
新冠疫情在全球仍在持续，我国长期存在新冠疫情从其他国家传入或在国内传播的风险。在常态化防控阶段，我国多地发生了局部新冠疫情，多数新冠病例为散发病例，但也报告了一些聚集性疫情或暴发疫情。冬春季是疫情高发季节；边境口岸城市暴发疫情的风险较高。对重点人群开展主动监测是早期发现疫情的有效途径。通过一系列综合防控措施，包括大规模核酸筛查、密切接触者追踪与隔离、对风险区域和人群进行分类管理、扩大社交距离以及严格出行管理等，局部新冠疫情得到了快速有效控制。在局部疫情防控中取得的经验将有助于我国新冠疫情的常态化防控。一系列新冠聚集性疫情或暴发疫情的发生暴露出我国新冠疫情防控工作存在的薄弱环节或不足之处，因此本文提出了一些改进未来新冠疫情防控工作的措施。
