Infectious diseases have remained one of humanity's biggest problems for decades. Multiple
disease infections, in particular, have been shown to increase the difficulty of diagnosing …

This paper is concerned with the formulation and analysis of an epidemic model of COVID-
19 governed by an eight-dimensional system of ordinary differential equations, by taking into …

In this work, we develop and analyze a deterministic mathematical model to investigate the
dynamics of monkeypox. We examine the local and global stability of the basic model …

Tuberculosis is an infectious disease caused by bacteria that most commonly affects the
lungs. Due to its high mortality, it remains a global health issue, and it is one of the leading …

In this study, we formulated and analyzed a deterministic mathematical model for the co-
infection of COVID-19 and tuberculosis, to study the co-dynamics and impact of each …

One of society's major concerns that have continued for a long time is infectious diseases. It
has been demonstrated that certain disease infections, in particular multiple disease …

In this work, we analyze the effective control of Lassa fever in a given population by
formulating and analyzing a nonlinear optimal control problem. We extend an existing …

In this study, we extend an existing Lassa fever model by incorporating four time-dependent
control functions which are identified as a preventive strategy, treatment care, and rodent …

This research aims to understand the effect of human awareness and the use of bed nets on
malaria control programs. A deterministic host-vector mathematical model was utilized and …

Malaria, a lethal protozoan disease transmitted through the bites of female Anopheles
mosquitoes infected with Plasmodium parasites, remains a significant global health concern …
