Abstract
The continuing coronavirus pandemic has come up with considerable questions in front of the world. Presently, India is
among concerned countries in Asia. Even though the recovery rate is more than the death rate, it is affecting human lives
and experiencing losses to the market. Several methods were employed to study the spread of novel coronavirus. Mathematical
modeling is one of the prominent techniques to evaluate the dynamics of novel coronavirus. In this work, we
extend the mathematical model SEIAQRDT by incorporating environmental transmission to analyze the transmission of
coronavirus in India. The notable aspect of the model incorporates asymptomatic population, quarantine individuals, and
environmental transmission factors. These factors have enormous significance in the ongoing COVID-19 outbreak. The
basic reproduction number R0 is calculated theoretically. Bifurcation analysis of R0 is also done analytically. The existence
and stability analysis of disease-free equilibrium (DFE) and endemic equilibrium (EE) points are established. The impact
of environmental factors in spreading COVID-19 pandemic is deliberated. The case study for India and Italy is presented
and compared with real data, and the results are in accordance with the real situation.
