  India is one of the worst affected countries by the Covid-19 pandemic at
present. We studied publicly available data of the Covid-19 patients in India
and analyzed possible impacts of quarantine and social distancing within the
stochastic framework of the SEQIR model to illustrate the controlling strategy
of the pandemic. Our simulation results clearly show that proper quarantine and
social distancing should be maintained from an early time just at the start of
the pandemic and should be continued till its end to effectively control the
pandemic. This calls for a more socially disciplined lifestyle in this
perspective in future. The demographic stochasticity, which is quite visible in
the system dynamics, has a critical role in regulating and controlling the
pandemic.
