Waterborne diseases are illnesses caused by pathogenic bacteria that spread through water
and have a negative influence on human health. Due to the involvement of most countries in …

Heartwater is a tick-borne illness that affects ruminants and is carried by the amblyomma
ticks. The condition may sometimes be deadly. This paper studies the Caputo fractional …

In this paper, we study the existence of numerical solution and stability of a chemostat model
under fractal fractional order derivative. First, we investigate the positivity and roundedness …

In recent decades, AIDS has been one of the main challenges facing the medical community
around the world. Due to the large human deaths of this disease, researchers have tried to …

In this article, we study a fractional order HIV/AIDS infection model with ABC-fractional
derivative. The model is based on four classes of a population. The study includes the …

In this work, we present and discuss the approaches, that are used for modeling and
surveillance of dynamics of infectious diseases by considering the early stage asymptomatic …

Background Tuberculosis (TB), caused by Mycobacterium tuberculosis, is a contagious
infectious disease that primarily targets the lungs but can also impact other critical systems …

In this study, we forecast the outbreaks of one of the most serious health issues in South
Africa, HIV/AIDS, using mathematical models. We consider an integer-and a fractional-order …

In this paper, two numerical methods based on the novel Bessel polynomials are developed
to solve the fractional-order HIV-1 infection model of CD 4+ T-cells considering the impact of …

A mathematical model of progressive disease of the nervous system also called multiple
sclerosis (MS) is studied in this manuscript. The proposed model is investigated under the …
