A Mathematical Model for the Within-Host Dynamics of Malaria Parasite with Adaptive Immune Responses

International Journal of Mathematics and Mathematical Sciences
Mathematical analysis of epidemics is crucial for long-term disease prediction and helps to guide decision-makers in terms of public health policy. In this study, we develop a within-host mathematical model of the malaria parasite dynamics with the ...

A diffusion-based HIV model with inflammatory cytokines and adaptive immune impairment

Frontiers in Applied Mathematics and Statistics
HIV continues to pose a critical threat to global public health, contributing to a high number of deaths worldwide. The virus predominantly attacks CD4+T lymphocytes, which are essential for coordinating immune responses.

Global stability analysis of a fuzzy HIV–TB co-infection model with environmental TB transmission

Scientific African
Human Immunodeficiency Virus (HIV) and Tuberculosis (TB) co-infection remains a significant global health challenge, further complicated by environmental transmission and inherent biological uncertainties.

A Nonlinear Quantum-Deformation-Fractional Model for Memory-Dependent Glucose–Insulin–Glucagon Dynamics With Real-Data Validation

Journal of Applied Mathematics
This study develops a nonlinear (q,τ)-fractional biophysical model for memory-dependent glucose–insulin–glucagon regulation. The model is motivated by the fact that metabolic regulation is governed by delayed insulin action, counter-regulatory glucagon ...

Stochastic analysis of Mpox epidemiology with vaccination strategies and environmental persistence

Scientific Reports
In the context of global preparedness and response strategies for Mpox outbreaks, we develop a comprehensive mathematical model to investigate its transmission dynamics, integrating critical factors such as vaccination coverage and environmental ...

Stability and bifurcation analysis of a nested multi-scale model for COVID-19 viral infection

Computational and Mathematical Biophysics
In this study, a nested multi-scale mathematical model is proposed and studied for COVID-19 viral infection. The well-posedness of the multi-scale model is discussed, followed by the stability analysis of the equilibrium points. The proposed model admits

Co-dynamics of hepatitis B and C viruses under the influence of CTL immunity

Alexandria Engineering Journal
Understanding the cytotoxic T lymphocyte (CTL) immune response against hepatitis B virus (HBV) and hepatitis C virus (HCV) infections is crucial, as these infections can lead to liver cirrhosis and cancer. Mathematical models provide valuable support for

The role of asymptomatic cattle for leptospirosis dynamics in a herd with imperfect vaccination

Scientific Reports
Leptospirosis is an emerging zoonotic disease with high health and economic damage. In this study, we developed a deterministic mathematical model that describes the dynamics of leptospirosis transmission within a cattle herd, incorporating asymptomatic ...

Stability of generalized models for HIV-1 dynamics with impaired CTL immunity and three pathways of infection

Frontiers in Applied Mathematics and Statistics
Highly active antiretroviral therapy (HAART) stands out as the most effective treatment for human immunodeficiency virus type-1 (HIV-1). While total eradication is still difficult, HAART can dramatically lower the virus's plasma viral level below the ...

Optimal control efforts to reduce the transmission of HPV in a fractional-order mathematical model

Boundary Value Problems
Human papillomavirus (HPV) is a sexually transmitted virus that causes cervical cancer in women and leads to death. In this research paper, we prepare a fractional mathematical model that contains a system of four fractional differential equations (FDEs)
