Since the starting of the year 2020, the whole world is facing a
challenge due to an outbreak of an unprecedented COVID-19
pandemic owing to a novel coronavirus. Here, a modified
susceptible–infected–recovered–dead model
has been used to analyze the time series data of the pandemic
for five countries. It is established that the present model is
capable of simultaneously explaining the temporal evolution of
active-infected, recovered, and dead population of all these
five countries. The key parameters governing the temporal
evolution of the spread of this pandemic are estimated and
compared.
