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.展开更多
