Clinical reports have shown that chronic hepatitis B virus (HBV) patients co-infected with
SARS-CoV-2 have a higher risk of complications with liver disease than patients without …

In this work, a fractional-order vaccination model for the novel Coronavirus 2019 (COVID-19)
incorporating environmental transmission is considered and analyzed using tools of …

In this paper, we construct the SV1V2EIR model to reveal the impact of two-dose vaccination
on COVID-19 by using Caputo fractional derivative. The feasibility region of the proposed …

This paper investigates a fractional derivative model of Chlamydia-Gonorrhea co-infection
using Caputo derivative definition. The positivity boundedness of the model is established …

Listeriosis is a life-threatening illness that can be spread through contaminated food. The
bacteria responsible for this disease is Listeria monocytogenes. The annual incidence rate …

In this paper, we introduce a Caputo-sense fractional derivative to an existing model for the
Chikungunya transmission dynamics, replacing integer derivative. After reviewing previous …

For diabetes mellitus therapies, Bergman's minimal model is proposed. The present study is
devoted to mathematical modeling and analysis of the diabetes mellitus model without …

Since November 2021, there have been cases of COVID-19's Omicron strain spreading in
competition with Delta strains in many parts of the world. To explore how these two strains …

The co-infection of HIV and Zika virus (ZIKV) poses a complex and understudied health
challenge, requiring a comprehensive investigation into the synergistic effects, potential …

This study explores the biological behaviour of the Monkeypox disease using a fractal–
fractional operator. We discuss the existence and uniqueness of the solution of the model …
