With the COVID-19 epidemic quickly under control in China in the early stage of 2020, global cooperation/communications may pose great challenges to epidemic control and prevention in the country. Large-scale spread by asymptomatic carriers was a concern. We obtained data on new cluster outbreak regions with COVID-19 caused by asymptomatic carriers from June 2020 to May 2021 in China, and reported the epidemiological characteristics, the possible routes of viral transmission and infection, and different control strategies. These results show the importance of regular screening for high-risk populations and differential management strategies for epidemic control, which provide an objective basis for suppressing the spread of the SARS-CoV-2 virus. These experiences can be used as a reference to minimize the subsequent spread of virus mutants in various places.
2020年初，随着中国境内新冠疫情迅速得到控制，全球合作/交流可能给该国的疫情防控带来巨大挑战。无症状感染者引发的大规模传播令人担忧。我们获取了2020年6月至2021年5月中国境内由无症状感染者导致的新冠疫情新聚集性暴发地区的数据，并报告了其流行病学特征、病毒传播和感染的可能途径以及不同的防控策略。这些结果表明了对高危人群进行定期筛查以及采取差异化管理策略进行疫情防控的重要性，为抑制严重急性呼吸综合征冠状病毒2（SARS-CoV-2）病毒传播提供了客观依据。这些经验可作为参考，以尽量减少病毒变异株在各地的后续传播。
