摘要
新型冠状病毒肺炎(COVID-19)无症状和症状前感染者无可感知的临床症状及体征,不易被检测出,所携带病毒的传播具有隐匿性,给疫情的控制带来了巨大挑战。由于潜伏期的长短,部分研究未能区分无症状和症状前感染者,得出无症状感染者比例较高。本文就无症状和症状前感染者的特点及传播,检测与控制等方面的最新研究进展进行综述。
The asymptomatic and pre-symptomatic infections of coronavirus disease 2019(COVID-19)has no perceptible clinical symptoms and signs,and it is not easy to be detected. The transmission of the virus carried by asymptomatic and pre-symptomatic patients is insidious,which brings great challenges to the control of the epidemic. Due to the length of the incubation period,some studies have failed to distinguish between asymptomatic and pre-symptomatic infections,resulting in a higher proportion of asymptomatic infections. This article reviews the latest research progress of characteristics,transmission,detection and control of asymptomatic and pre-symptomatic infection.
