Epidemiological Models for Infectious Diseases and Applications in COVID-19

Infectious diseases at all times are a threat to human beings, including the ongoing COVID-19 pandemic. Disease modelling is one of the tools to study infectious diseases in the field of epidemiology. Mathematic models as well as computer simulation models, are used to predict the spread of the infection, and ways of controlling the infection. From simple to multiple compartment models are formulated to analyse various infectious diseases. In the current scenario of the COVID-19 pandemic across globe, several models were devised to analyse the impact of the COVID-19. Based on the proposed models, countries have taken different measures to control the spread of the COVID-19 including restrictions like lockdown. This chapter details the various compartmental models in disease modelling and applications of the models in the current scenario of COVID-19.
