The study primarily aims at modelling the current COVID-19 pandemic to understand its spread in India and to simulate different strategies that affect its future spread and long-term impact. A modified compartmental model will be developed and trained using real-time data of spread of the pandemic in India. Effects of temperature, age distribution, temporal testing strategies and heterogeneous lock-downs on the spread will be studied. A particle-based model will also be developed to account for heterogeneity in population density, transmission rates and containment strategies, to develop fundamental insights into kinetics and management of infectious diseases.
