Query: Analyzing COVID-19 pandemic with a new growth model for population
  ecology   We have proposed a new form of growth rate for population ecology. Generally,
the growth rate is dependent on the size of the population at that particular
epoch. We have introduced an alternative time-dependent form of growth rate.
This form satisfies essential conditions to represent population growth and can
be an alternative form for growth models to analyze population dynamics. We
have employed the generalized Richards model as a guideline to compare our
results. Further, we have applied our model in the case of epidemics. To check
the efficacy of our model, we have verified the 2003 SARS data. This model has
estimated the final epidemic size with good accuracy. Thereafter, we intend to
describe the present COVID-2019 pandemic. We have performed our analysis with
data for Italy, Spain, and Germany. Following, we have tried to predict the
number of COVID-19 cases and the turning point for the USA, UK, and India.
