The onset of symptoms starts between 2 and 14 days after infection with 3 to 6 days being the average depending on the cohort. [1] Outliers exist, such as one patient that did not show symptoms for 27 days. It is unknown when a person becomes infectious, but so far data suggests that its days before symptoms appear for most patients and as many as two thirds may be completely asymptomatic.
