We propose a compartmental mathematical model for the spread of the COVID-19 disease
with special focus on the transmissibility of super-spreaders individuals. We compute the …

In this article, the mathematical model with different compartments for the transmission
dynamics of coronavirus-19 disease (COVID-19) is presented under the fractional-order …

We establish a stochastic HIV/AIDS model involving the susceptible with protection
awareness within a total population. The mechanism of dynamic behaviors of the stochastic …

We discuss a fractional-order SIRD mathematical model of the COVID-19 disease in the
sense of Caputo in this article. We compute the basic reproduction number through the next …

The progression of the still ongoing COVID-19 epidemic must be studied in the world of
differential operators other than those specified with integer-order temporal derivatives …

Nigeria, like most other countries in the world, imposes lockdown as a measure to curtail the
spread of COVID-19. But, it is known fact that in some countries the lockdown strategy could …

In recent years, many new definitions of fractional derivatives have been proposed and used
to develop mathematical models for a wide variety of real-world systems containing memory …

We investigate an epidemic model based on Bailey's continuous differential system. In the
continuous time domain, we extend the classical model to time-dependent coefficients and …

To achieve the aim of immediately halting spread of COVID-19 it is essential to know the
dynamic behavior of the virus of intensive level of replication. Simply analyzing experimental …

The current work analyzes the HIV/AIDS model under stochastic fractional differential
equations in the Caputo sense. The articulation of the model both in integer and arbitrary …
