Result: Notably, all the mutations associated with the recovered group (
S2015R,
Y789Y,
T2016K,
S194*,
A4489V) showed a frequency flip, whereas two mutations associated with the mortality group showed a shift in their frequency from our cohort to global level.
Discussion: Moreover, a significant frequency flip (p-value = 0.0001) was seen for the five mutations,
S2015R,
Y789Y,
T2016K,
S194*, and
A4489V, in the recovered with a low global presence, indicating that the mutations associated with
COVID-19 recovery are deselected by the virus during its evolution.
