Objective Several essential factors have played a crucial role in the spreading mechanism of
COVID-19 (Coronavirus disease 2019) in the human population. These factors include …

Without any vaccine or medical intervention to cure the infected individual from COVID-19,
the non-pharmaceutical intervention become the most reasonable intervention against the …

Our research focuses on studying a COVID-19 SIR model for discrete cases, incorporating bi-
linear phenomena and a constant rate of recovery. We have interested in analyzing the …

SARS-CoV-2 is the newly emerged infectious disease that started in Wuhan, China, in early
December 2019 and has spread the world over very quickly, causing severe infections and …

The pandemic of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) took
the world by surprise. Following the first outbreak of COVID-19 in December 2019, several …

This article aims to apply a mathematical model to investigate the spread of malaria by
considering vector bias, saturated treatment, and an optimal control approach. A …

Adherence to public health policies such as the non-pharmaceutical interventions
implemented against COVID-19 plays a major role in reducing infections and controlling the …

In this paper, we propose a modified fractional diffusive SEAIR epidemic model with a
nonlinear incidence rate. A constructed model of fractional partial differential equations …

In this paper, we establish an SIVR model with diffusion, spatially heterogeneous, latent
infection, and incomplete immunity in the Neumann boundary condition. Firstly, the …

In this article, we propose and analyze a mathematical model of COVID-19 transmission
among a closed population, with social awareness and rapid test intervention as the control …
