The outbreak of a novel coronavirus
(SARS-CoV-2) since December 2019 in Wuhan,
the major transportation hub in central China,
became an emergency of major international
concern. While several etiological studies have
begun to reveal the specific biological features
of this virus, the epidemic characteristics need
to be elucidated. Notably, a long incubation
time was reported to be associated with
SARS-CoV-2 infection, leading to adjustments
in screening and control policies. To avoid the
risk of virus spread, all potentially exposed
subjects are required to be isolated for 14 days,
which is the longest predicted incubation time.
However, based on our analysis of a larger
dataset available so far, we find there is no
observable difference between the incubation
time for SARS-CoV-2,
severe acute respiratory syndrome coronavirus
middle east respiratory syndrome coronavirus
(MERS-CoV), highlighting the need for larger
and well-annotated datasets.
