Abstract

Abstract: COVID-19 has been plaguing global health for nearly a year.During the past year，many governments took arious measures such as closing schools and office-buildings，imposing social distancing to cut off the virus' transmission route.However，in the gradual return to normality，asymptomatic patients will，and already have，pose grave challenges.This paper reviews the proportion of asymptomatic COVID-19 cases in the global population，the role these cases have played in the transmission，and measures to restrict COVID-19 transmission through asymptomatic cases.

Key words: Pneumonia, COVID-19, SARS-CoV-2, Asymptomatic carriers, Control

摘要： 新型冠状病毒肺炎（COVID-19）已在全球流行近一年，对世界人口健康造成巨大打击。许多国家为切断病毒传播途径，采取关闭学校和工作场所、强制公众保持社交距离等措施。在逐步恢复正常的工作和生活秩序过程中，无症状感染者对COVID-19流行的影响无疑是一个重要挑战。本文针对无症状感染者在人群中的比例、无症状感染者在传播中的作用以及限制无症状感染者造成的病毒传播等方面的研究进展进行综述。
