Mathematical Modelling of Fractional-order Covid-19 Pandemic With Memory Effect: A Review

Abstract

Mathematical models with memory effect play an important role in the field of epidemiology. The fractional-order derivatives are powerful tools to characterize the memory effect in the dynamical systems of infectious diseases. Hence, we attempt to present a systematic survey on the fractional-order compartmental models of Covid-19 pandemic to explain how the fractional-order models have been employed to study and forecast the spread of Covid-19 pandemic. Such non-integer order models can help decision makers in control programs to put strategic plans to control Covid-19 outbreakMathematical models with memory effect play an important role in the field of epidemiology.
