Key quote: "The fact that asymptomatic persons are potential sources of 2019-nCoV infection may warrant a reassessment of transmission dynamics of the current outbreak. In this context, the detection of 2019-nCoV and a high sputum viral load in a convalescent patient (Patient 1) arouse concern about prolonged shedding of 2019-nCoV after recovery." In plain language: * individuals can transmit 2019-nCoV before developing symptoms; * individuals may or may not be able to transmit it after recovery to some extent (this is not yet known); and * current predictions for the size outbreak may have to be revised to account for these transmission features.
